We stock bike bearings for road bikes or mountain bikes to cover different applications. Our thin-section radial ball bearings, often referred to as cartridge bearings, can be used as bottom bracket bearings or bike wheel bearings (hub bearings) and are available with metal shields, rubber contact seals or our “2RU” rubber low friction seals. For greater corrosion resistance, we can supply these in stainless steel and with waterproof lubricants.
