Rolko Replacement Wheelchair Bearings Buyer’s Guide
The Rolko Replacement Wheelchair Bearings are precision-engineered replacement components designed to restore smooth, low-friction rolling to wheelchair casters and rear wheels. Constructed from high-durability steel and featuring dual-rubber seals (2RS), these bearings protect internal ball bearings from dirt, hair, and moisture—ensuring long-lasting mobility and effortless propulsion across all terrain types.
Double-Sealed 2RS Protective Shield
Each bearing in the Rolko series is equipped with rubber seals on both sides (2RS). This dual-seal design prevents dust, hair, grit, and water from entering the internal raceway, preserving factory lubrication and extending overall component service life.
Precision Smooth-Rolling Ball Bearings
Built with tight tolerances for exact inner and outer diameter matching, Rolko bearings reduce rotational friction and wobble. Upgrading worn bearings reduces push effort, minimizing fatigue on the user’s hands, wrists, and shoulders during daily navigation.
