Oil Impregnated Powder Metallurgy Stainless Steel Solid Sleeve Bushing
Self-lubricating sintered bearings have some advantages compared to other types of dry sliding bearings:
Reliability: The constant oil presence eliminates the risk of seizure, and allows the bearing to work during thousands of hours without wear.
Economy: Maintenance-free, no need for lubricants.
Performance: Able to work under loads of up to 10 MPa, and speeds up to 2.5 m/s. The maximum working PV is is the range of 2.45 N/mm2•m/s, but can be surpassed in special cases. The dimensional precision is very high (up to IT 5 in diameter), and produces extremely low noise.
