10pcs 6900 2RS 10 mm x 22 6 Ball Bearings Rubber Seal Deep Groove double shielded Bearing For Skateboarding Inline Skates Roller

Durable Material: The bearing is made of bearing steel, which is durable, anti-rust, anti-corrosion, smooth-rolling, noise reduction, durability, and prolonged service life. Rubber Cover: The bearing is sealed with rubber to effectively prevent the intrusion of sand, dust, water, and other foreign objects, and increase the service life of the bearing. Low noise & high speed:Low noise, the friction coefficient of deep groove ball bearings is very small, and the limit speed is also very high. Bearing Load: The built-in steel ball is not easy to deform. Rolling bearings use rolling elements to maintain separation between moving parts to reduce rotational friction and support radial and axial loads. Wide Applications: Deep groove ball bearings can be used in trolleys, gearboxes, meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, roller skates, tools, etc.
