Unrivalled Performance and Longevity with SBS Sleeve Bearings/Plain Bearings
Sleeve bearings, also known as plain bearings, play a crucial role in reducing friction and wear in rotating machinery, thus functioning as a suitable friction bearing. Although not the most common type of bearing, they are a very close second. SBS Bearings ensures that our sleeve bearings are engineered to offer unmatched reliability and longevity, ensuring smooth operation even under high loads and challenging conditions. Sleeve bearings are well-suited for high-load applications because their design distributes forces over a large contact area between the shaft and the bearing surface.
Sleeve bearings offer several advantages, including lower cost, less maintenance, reduced noise at low speeds and easier installation. Additionally, sleeve bearing performance is marked by a higher load capacity, especially shock load resistance due to their greater contact zone, which is important in relation to inner diameter specifications .

SBS sleeve bearings are designed to excel in high-performance applications, providing stability and support where it is most needed through various material options . Whether used in heavy machinery, automotive industries, or precision equipment, our bearings demonstrate superior load-bearing capabilities and consistent performance.
Sleeve bearings consist of metal, plastic, sintered metal bushings, or fiber-reinforced composite sleeves. These reduce vibrations and noise by absorbing friction between two components, utilising a sliding motion.
These bearings also perform well at high speeds when designed with appropriate materials,, and tolerances. The large contact area of sleeve bearings helps distribute loads evenly, reducing localised heating and deformation. Properly engineered, sleeve bearings provide quiet, efficient, and reliable performance even under high-speed conditions.

Some of application examples you can find here.
Custom sleeve bearings are well-suited for linear movements because they can be precisely designed to match the load, speed, and environmental conditions of the application. By optimising materials, dimensions, and lubrication methods, these bearings provide smooth, low-friction sliding along shafts or guide rails. This tailored approach ensures consistent performance, minimises vibration or stick-slip motion, and allows the bearing to handle high loads or harsh conditions effectively in linear motion applications.
For example, sleeve bearings are well-suited for hard steel shafts. Their sliding-contact design allows them to handle the high hardness and smooth surfaces of steel shafts without damage, especially when combined with proper lubrication or self-lubricating materials. Sleeve bearings are reliable for heavy-duty or high-speed applications where durability and low maintenance are essential, even when paired with hard, precision-machined shafts.
Prolonging Plain Bearing/Bushing Service Life through Optimal Lubrication Practices
Lubrication is a vital aspect of bearing maintenance, and at SBS Bearings, we ensure that its importance is never underestimated in maintaining low friction. SBS Bearings emphasises the importance of lubrication, providing expert advice to ensure that your sleeve bearings (plain bearings) operate at their full potential, maximising performance through proper oil usage and extending their service life.
Proper lubrication practices, including the use of an external lubricant, can significantly minimise wear, and protect against corrosion, ensuring that your sleeve bearings continue to operate efficiently over time. Self-lubricating bearings/bushings are also another great option depending on your needs as they do not need extra oil or grease.
Self-Lubricating Sleeve Bearings
Self-lubricating sleeve bearings/bushings are crucial as they help in reducing maintenance and labour costs. They are also durable and perform well in harsh environments, no requiring any types of oil or grease. Maintenance-free sleeve bearings are advantageous because they provide reliable, long-term operation without the need for regular lubrication or upkeep. This eliminates downtime, labor, and the risk of lubricant contamination, making them ideal for hard-to-access or continuously operating machinery. These maintenance-free free bearings offer long service lives, consistent good performance without attracting contaminants and have the ability to be customised material/surface-wise for varied applications. They are a great example of a cost-effective bearing choice.
Axial and Radial Loads
Sleeve bearings are designed to support both radial and axial loads, though their capacity for each depends on the bearing’s design and material. Properly engineered, these bearings provide smooth, reliable motion under combined load conditions, making them suitable for applications ranging from rotating shafts to thrust-heavy machinery components.
Sleeve bearings are also versatile components that support linear or rotational movement by providing a smooth interface between a shaft and the bearing surface. In rotational applications, the bearing allows the shaft to turn steadily, reducing wear and heat generation. In linear applications, sleeve bearings enable shafts or rods to slide smoothly along their axis with minimal resistance. Their simple design ensures reliable performance in these linear or rotational movements.
Reduce Friction
Sleeve bearings diminish friction by maintaining a thin film of lubricant between the shaft and the bearing surface. This lubricating layer prevents direct metal-to-metal contact, allowing the shaft to slide smoothly within the bearing. As the shaft rotates, the lubricant forms a hydrodynamic or boundary film that supports the load and minimizes shear resistance. In self-lubricating sleeve bearings, the lubricant is often impregnated within the bearing material itself and released gradually during operation, ensuring consistent performance without the need for frequent maintenance.
Cylindrical Bearing
Cylindrical bearings are a type of sleeve bearing characterized by their simple, hollow cylindrical shape that supports a shaft along its entire length. Like other sleeve bearings, they operate through sliding contact between the shaft and the bearing surface, often with a lubricating film or material to reduce friction.
A cylindrical sleeve is essentially the core component of a cylindrical bearing. It is a hollow, cylindrical tube, typically made of metal, bronze, or a composite material, that fits around a shaft to provide a smooth sliding or rotational interface. The cylindrical sleeve serves as the bearing surface that supports radial loads and allows motion, while often incorporating lubrication either externally applied or impregnated within the material.
A simple cylindrical bearing is a basic type of sleeve bearing consisting of a plain, hollow cylinder that supports a shaft along its length. It provides a smooth surface for the shaft to slide or rotate against, usually with a layer of lubricant—either applied externally or impregnated in the bearing material—to reduce friction and wear. Essentially, all cylindrical bearings are sleeve bearings, but the term emphasizes their geometry and typical use in applications requiring straightforward, low-maintenance support for rotating or sliding shafts.
Flanged Bushing
These bushings are a type of sliding bearing that includes an extended rim, or flange, on one end of the cylindrical sleeve. The flange provides an additional surface while the main cylindrical portion handles radial loads. A flanged sleeve is the actual cylindrical component of this bushing. It consists of a hollow cylinder with an integrated flange on one end. This flanged sleeve design prevents the shaft from moving lengthwise through the bearing, improving stability and reducing the risk of misalignment.
Journal Bearings
Journal bearings are designed to support rotating shafts by providing a smooth, low-friction interface over a large contact area. They are particularly effective at handling high radial loads because the load is distributed across the length of the shaft rather than concentrated at points, as in rolling-element bearings. Journal bearings also perform well at high speeds, reducing friction and wear. Their simple, robust construction makes them durable, low-maintenance, and ideal for applications where reliability under heavy loads and continuous operation is critical.
Thrust Washer Designs
Thrust washer designs are a type of bearing specifically intended to support axial loads. Typically, a thrust washer is a flat, disc-shaped component that slides against a rotating surface, often made from materials like bronze, steel, or self-lubricating composites. Thrust washers can be used together in machinery to provide complete support for shafts, ensuring smooth, low-friction operation and protecting components from wear.
Plastic Bearings
Plastic sleeve bearings are highly valued for their combination of corrosion resistance, and self-lubricating properties. Made from engineered polymers such as PTFE, nylon, or UHMW, they can operate without external lubrication, reducing maintenance requirements. The lightweight nature of plastic and chemical resistance make them ideal for harsh or wet environments. Additionally, they can absorb vibration and tolerate misalignment better than metal, while providing smooth, quiet operation. These characteristics make them especially useful in applications ranging from industrial machinery to automotive components and household appliances.
Ball Bearings
Sleeve bearings are often preferred over ball bearings in applications where simplicity, durability, and cost-effectiveness are key. Unlike ball bearings, which use rolling elements, sleeve bearings rely on a lubricating film to support motion, making them quieter and better suited for heavy loads at lower speeds. Rolling elements in ball bearings are not always in certain applications because they introduce complexity, higher cost, and sensitivity to operating conditions. They are also more tolerant of shock, vibration, and contamination, and require less maintenance, especially when self-lubricating materials are used. Additionally, sleeve bearings can operate reliably in environments, making them an excellent choice for rugged or continuous-duty applications.
