Single row – crossed roller

This bearing is comprised of an Inner Ring, Outer Ring, cylindrical rollers and seals.  Hardened V-groove raceways provide two roller paths for the cross rollers (alternating rollers at right angles). Each set of alternating rollers take the load in one direction. This design provides increased capacity, greater stiffness and a lower spring rate per unit size than the single row four-point contact design. With its rectangular design, this bearing is available in Internal, External, or no-gear designs.
