Bearings, Rollers & Sliding Components

Bearings, rollers, bushes and slide plates take constant friction, load and often washdown or dust exposure that would chew through unprotected metal-on-metal contact. Engineering plastics solve this by running dry or near-dry, resisting corrosion, and shrugging off the grit that ruins conventional bronze or steel bushings in mining, food processing and general manufacturing plant.

At Perspex Online we cut nylon, acetal (POM), UHMWPE and Nylatron rod to length or machine it to finished bearing and roller blanks, so maintenance crews and OEMs get parts sized to the job rather than the nearest off-the-shelf metric size.

Correct sizing is what actually determines service life. As a rough guide, PV (pressure-velocity) limits vary from roughly 0.03 MPa·m/s for standard nylon bushes under continuous dry running up to several times that for oil-filled grades — we can talk through loading with you before you commit to a material.

All four materials handle intermittent shock loading well versus brittle plastics, and none will seize or gall the way unlubricated metal bearings do, which matters most in washdown or outdoor plant where grease attracts contamination.

We turn rod on our own CNC lathes to your print or sample part, holding tolerances suited to press-fit and running-clearance requirements. Send a drawing, a sketch with key dimensions, or the worn part itself and we'll quote a replacement.

Standard turnaround on machined bearing and roller blanks is typically 3-5 business days, with rush options available for breakdown situations — call us if a machine is down.
