What is Oil Free

What is Oil Free Material?

Self-lubricating material for plain bearing parts were developed to provide advantages over traditional oil-grooved parts. The Oil FreeTM parts require no additional lubrication or a little lubrication to work. This provides lower maintenance needed specially for difficult to lubricate environments. Lower the impact of neglect to perform maintenance, lower the cost of overall maintenance.
Also provide additional advantage for the environment, and eliminate the problem of oil contamination.

Standard Products

Standard parts are sold under the Oil FreeTM trademark through our trading company branch.
