OILES Drymet ST is a self-lubricating bearing consisting of an OILES 80 overlayer, a sintered bronze interlayer, and a steel backing.
Features
ball Realized high load carrying capacity and excellent wear resistance with a low co-efficient of friction without lubrication
ball Shows excellent performance even in applications where an oil film is difficult to form due heavy load, oscillating motion and frequent intermittent operation
ball Thin-wall construction for compact design
ball Excellent dimensional stability, physical strength, thermal conductivity
ball Inside diameter could be machined if high dimensional accuracy is required
ball A variety of standard sizes available
