Maintenance-free self-lubricating sliding bearings AISI 420 inner ring C86300 bronze spherical plain oilless sliding bearing bush
This type of spherical plain oilless bearing features a stainless steel AISI 420 inner ring and C86300 bronze with graphite or PTFE outer ring. The running film is sprayed with PTFE or MoS2 for optimal lubrication.
Material Structure
- Inner Ring: Stainless steel: SS316, SS304, AISI 420
- Outer Ring: Oilless bronze graphite bearing C86300 with Graphite/PTFE/SL4
Characteristics
- Maintenance-free operation with low friction and long service life
- Suitable for higher loads than other self-lubricating spherical bearings
- Applicable to large oscillating angles in circumferential oscillating motion
- Customized designs available to meet specific requirements
- Utilizes highly resilient brass alloy CuZn25Al5Mn4Fe3 (C86300) for extreme high-performance combined with self-lubricating properties
Application
Designed for applications with low sliding speeds and very high loads. Spherical plain oilless sliding bearings are widely used in gate valves, hydraulic turbines, crane equipment, and similar industrial applications.
