JIAERDA Oilless bushing from CHINA are commonly used in applications requiring a completely self lubricating, copper base alloy bearing material. Choose from our many standard bushing and bearings, in both metric sizes, or let us produce a custom part to your exact specifications.
Design and calcuation of working pressure:(Oilless Bushing).
The working presurre of the Oilless Bushing is calculated as the follow formula: P=Fmax/d.L≤Po
Fmax-the max radial(N)sustained by bearing
d-Diameter of bearing(mm)
L-Length of bearing(mm)
Po-Allowed load of bearing(Mpa) is calcualted according to the sliding speed as the PV factor abtains the dynamic capacity, and the result is divided by a safety coefficient 1.4 and get the allowed load.
The JIAERDA MACHINER Oilless bushing requires no oil or grease, instead a graphite film is formed between the surfaces to provide a reliable, mechanical barrier of lubrication. Additional capabilities include graphite filled grooves and wear plates. Oilless bushing can be manufactured from a number of bronze alloys to meet the specific requirements of your application.
