Needle Rollers & Shafts

Needle rollers are long, cylindrical rolling elements with a small diameter relative to their length. They are commonly used in needle roller bearings to reduce friction while supporting high radial loads in compact spaces. Needle rollers are widely used in automotive, industrial machinery, gearboxes, transmissions, and precision engineering applications where space efficiency and durability are essential.

Needle rollers work by rolling between the shaft and the bearing race, significantly reducing friction compared to sliding contact. This rolling action allows equipment to operate more smoothly while supporting high radial loads with minimal wear. Their slim profile enables compact bearing designs without sacrificing load-carrying performance.

Choosing the correct needle roller and shaft depends on several factors, including load capacity, shaft diameter, operating speed, surface hardness, lubrication, environmental conditions, and application requirements. Bowman's engineering team can help you select the most suitable combination to ensure optimum performance, reliability, and service life.

Yes. Bowman Plain Bearings manufactures both standard and custom needle rollers and shafts to meet specific customer requirements. Custom solutions are available in a variety of sizes, materials, tolerances, and surface finishes, ensuring the components are precisely matched to your application and operating conditions.

Precision shafts are used to provide accurate rotational or linear movement in mechanical systems. They serve as the running surface for bearings and other moving components, ensuring smooth operation, reduced friction, and precise alignment. Precision shafts are commonly found in industrial machinery, automation equipment, conveyors, electric motors, gearboxes, medical devices, and automotive applications where high accuracy and reliability are required.
