The raceways in the inner and the outer rings of the crossed cylindrical roller bearings are inclined at an angle of 45 °. The diameter of the rollers is larger than the length. They provide stiff bearing arrangements and can carry very heavy loads. They require minimum of space and require very less space. They can accommodate radial, axial and moment loads. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. Apart from the standard single row they are available in other: Single or double row bearings in full compliment or caged forms Bearings with clearance and preload Bearings with integral gears for bolt attachments in bearing rings Bearings with integral seals.
