Wheel & Caster Housing Bearings "1/2 or 5/8"
PER4MAX

Product Overview
Wheelchair bearings are critical, low-profile mechanical components that ensure a smooth, quiet, and effortless ride. Over time, friction, hair, dust, dirt, and moisture degrade the lubrication inside old bearings. This wear leads to tracking alignment problems, loud squeaking, caster flutter, wheel wobble, and increased physical strain on your upper body. Servicing or replacing your bearings at least once a year preserves your wheelchair's handling and enables you to roll farther with every push.
These high-quality replacement bearings utilize specialized double-lipped rubber seals (2RS) or shielded enclosures rather than standard metal seals. The tight rubber contact completely blocks water, grit, and road grime while trapping internal synthetic grease to prevent internal rust and premature failure.
