water lubricated bearing

JIAERDA Oilless bushing from CHINA is 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 calculation of working pressure:(Oilless Bushing).

The working pressure of the Oilless Bushing is calculated as the following 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 calculated according to the sliding speed as the PV factor obtains the dynamic capacity, and the result is divided by a safety coefficient of 1.4 and gets 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. The oilless bushing can be manufactured from a number of bronze alloys to meet the specific requirements of your application.
