the Brass Wrapped Bushing bushing is made of copper alloy CuZn31Si that is of higher density with its surface punched with oil sockets or grooves, which depends on the customer's requirements. This type of bushing has better load capacity, anti-erosion, and anti-abrasion capacity.

Material: CuZn31Si

Hardness: HB90~150

Temperature limit: -100℃~200℃

Load capacity: 90N/mm2

Speed limit: 2m/s



Material Structure


Material: CuZn31Si1.




High load capacity, good wear-resistance.

Good stability under load, particularly suitable for oscillating bearing.

Grease depots for long-term lubrication.




Standard cylindrical bushings are available.

Special designs are produced based on your design.




This type oilless bronze bushing is widely used in construction machinery, machine tooling etc.
