Shaft Sleeve Bushing

Bearings require precise support to maintain alignment during high-speed and high-load operation. We have been manufacturing precision bearing-related components since 2011 and have supplied sleeve parts to Sany Heavy Industry, whose equipment operates under demanding speed and load conditions. This experience supports our capability in high-precision concentric components.

This Shaft Sleeve Bushing is used in industrial robot joints, automotive drive modules, servo systems, and precision rotary assemblies. It functions to securely position bearings and prevent axial or radial displacement, ensuring stable rotation.

Materials include 45# steel, 40Cr alloy steel, and GCr15 bearing steel, providing a balance of strength, wear resistance, and dimensional stability.

Our machining processes ensure strict control of geometric accuracy and surface quality.

This Shaft Sleeve Bushing features an inner diameter tolerance of IT6–IT7 grade and an outer diameter tolerance of IT7 grade.

End face squareness is controlled within ≤0.02 mm, and coaxiality is maintained within ≤0.015 mm to ensure precise alignment with the bearing system.

Surface roughness is controlled at Ra ≤ 0.8 μm for smooth fitting and reduced friction.

It supports operating speeds up to 6000 r/min and works within a temperature range of -30°C to 120°C.

Surface treatments include black oxide coating, phosphate coating, and anti-rust oil for improved corrosion resistance.

We provide more than components-we deliver reliable alignment solutions for precision machinery.

This Shaft Sleeve Bushing is suitable for industrial robot joints, servo motors, precision drive systems, and automated production line modules.

It is designed to maintain bearing alignment and improve rotational stability under continuous operation.

With over a decade of experience since 2011, we are committed to producing high-precision mechanical components that ensure long-term stability and performance in high-speed systems.
