The steel base self-lubricating plain bearing with sintered tin bronze layer offers a robust and durable solution for various industrial applications. The steel base provides excellent structural support and rigidity, while the sintered tin bronze layer ensures smooth and efficient operation through its self-lubricating properties.
The sintered bronze layer exhibits high wear resistance and load-bearing capacity, making it suitable for high-demand applications. The self-lubricating nature of the bearing reduces the need for regular lubrication, thereby minimizing maintenance requirements and operational downtime.
Wh used in heavy machinery, automotive components, or other industrial equipment, this steel base self-lubricating plain bearing with sintered tin bronze layer ensures reliable and long-lasting performance.

POM Composite Bearing, Replacement POM Bush Bearing | Self-lubricating Composite Bushings
POM composite bushings are referred to as prelubricated because their material is designed to operate with marginal lubrication. These bushing type effectively fills the gap between fully lubricated and dry sliding bushings.We offer a wide range of straight POM composite bushings. The advantages of these sleeves are:
• maintenance-free operation
• very good frictional properties
• high load capacity
• high sliding speed
• low working clearance

Pom Composite bushing Characteristics
Pom Composite lubricated bushing can be used for grease or oil lubrication applications, or in an oil-free environment
The standard parts contain grooves in the sliding layer of the contact parts, which can store grease or friction debris.
The smooth sliding layer can be designed and provided upon request
Composite bearing sleeve has the best performance under relatively high load and low speed, and the highest relative life
Composite bearings are used in environments of linear, oscillating and rotational motion
All kinds of bearing parts are available from stock
