Cylindrical bore type for 2.188 in. / 55.563 mm. shaft diametr, outer ring surface is spherical, inner ring extented on both sides with set screw locking.
Made of hardened carbon chromium bearing steel, most widely used material for bearing rings and rolling elements.
Principal dimensions is 2.188х4.331х2.563 in. equal to 55.563х110х65.1 mm.
The inner ring is located on the shaft by two grub screws offset by 120°, suitable for bearing arrangements with a constant direction of rotation or, under low speed and load, for an alternating direction of rotation.
Without coating.
Two lubrication holes in the outer ring, one on each side, positioned 120° apart for re-lubrication feature.
Capped by contact seal and an additional plain sheet steel flinger on both sides. Interference fit for the flinger on the inner ring shoulder to improve considerably the effectiveness of the seal without increasing friction. Greased with the appropriate amount of high quality grease under clean conditions. Recommended for the more contaminated environments.
Relubrication can extend bearing service life if the bearing have lubrication holes.
Polymer cage.
Inch series product.

Radial insert ball bearings are based on sealed deep groove ball bearings, this is ready-to-fit machine elements. They are highly suitable where predominantly radial loads must be supported. These bearings also give quieter running and lower vibration levels than standard radial insert ball bearings.
