The Story
The Black Bearings B3 6902 Hub Bearing is a precision-built radial bearing designed for demanding, load-heavy frame pivot applications. With full complement construction, premium high-fill grease, and SAE52100 chrome steel races and balls, it helps manage loads efficiently while supporting smooth, durable movement. Its 2RS seals add water and dust resistance, making it a reliable choice for rough rides, as long as you use it in reciprocating frame pivot setups rather than continuously rotating parts.
