Bearing for running roller of skate, skateboard etc.

摘要

The running roller (4) is held so that it can turn on a carrier bolt by two ball bearings (6) spaced out from each other. These ball bearings are fitted with a seal (11) and can be dismantled. The inner (8) or outer (7) ring has a shoulder and a running track profile. This profile, on the side facing away from the shoulder, passes at one side on the groove base into a cylindrical running track. The running track seals are in the form of a rubber covering washer or a steel covering washer (11) which is held by a spring ring (12) in a groove in the outer ring.
