This pair of 5 x 10mm ball bearings features Teflon seals and is supplied as a general RC parts accessory. The Teflon sealing reduces ingress of dust and helps hold lubrication in place, which is useful for compact bearing locations within models.
These bearings fit components designed for 5 x 10mm units, for example wheel hubs, small gearbox shafts and other rotating elements. Use the original retention or press-fit method suited to your chassis and avoid applying excessive lateral force when pressing the bearing into place.
From a performance perspective, replacing bushings or worn bearings with sealed ball bearings can lower friction and deliver smoother drivetrain and steering response. Check seals periodically and swap bearings in matched pairs to preserve axle balance.
