INA IR55X65X28 Inner Ring 55x65x28 mm

The inner ring, also known as bearing race or rolling bearing inner ring, with type number IR55X65X28 from INA is a precise mechanical component for needle bearings. It has the dimensions 6.5 x 2.8 x 5.5 cm and weighs 0.198 kg. Specific variants of this inner ring offer a grind-free surface, which is excellently suited for use with radial shaft seals. Inner rings are crucial for the precise guidance of the rolling elements in needle bearings and enable the efficient transmission of radial and, if applicable, axial forces under demanding conditions. They are typically used in mechanical engineering and automation technology applications, such as in gearboxes, pumps, agricultural machinery, or for crankshaft bearing arrangements.

Inner ring for needle bearings with an inner diameter of 55 mm, outer diameter of 65 mm, and width of 28 mm. Some variants feature a grind-free surface suitable for radial shaft seals.
