SF-1 Oil free lubricated bearingsDetailed product description：

SF-1 oil-free lubricated bearings are suitable for working parts that cannot be lubricated or are difficult to work on, with good wear resistance, low friction coefficient, and long service life; Good running in performance, low noise, no pollution, and good corrosion resistance; The transfer film formed during operation plays a role in protecting the grinding shaft without biting the shaft; The low machining requirements for grinding shafts have reduced the processing costs for users.

Available forms: straight sleeve, flanged shaft sleeve, WC thrust washer, sliding plate, and other non-standard components.
Tolerance: It is generally recommended to have a seat hole tolerance of H7 and a shaft diameter tolerance of f7 or h8.
