Cylindrical bore type for 2.25 in. / 57.15 mm. shaft diametr, outer ring surface is spherical, inner ring extended on one side with set screw locking.
Made of hardened carbon chromium bearing steel, most widely used material for bearing rings and rolling elements.
Principal dimensions is 2.250х4.331х1.909 in. equal to 57.15х110х48.5 mm.
The inner ring is located on the shaft by two cup point hexagonal set 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 standard contact seal on both sides. Standard seals consist of a stamped sheet steel washer with a seal lip made of NBR, vulcanized to its inner surface. Non-contact sheet steel washer, a narrow gap with the inner ring shoulder protect the seal against coarse contaminants. Greased with the appropriate amount of high quality grease under clean conditions.
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.
