552-4638: Sleeve Bearing

A Straight Sleeve Bearing is a sliding contact bearing in which the surface of the shaft slides over the surface of the bush. It consists of a cylindrical sleeve with a smooth inner surface that allows a shaft to rotate inside it with minimal friction. The oil grooves are cut into the plain bearing surfaces to assist in the distribution of the oil between the rubbing surfaces. Attributes: • Carburization depth is in the range of 1.2mm - 2.2mm and hardness lies between 59 - 64 HRC • Provided with elliptical groove (holds more lubricant than spiral groove) to distribute lubrication more evenly across the bearing surface • Provided with 4 oil holes of size 6mm • Possesses high shock load resistance, minimize vibration (and therefore noise) Applications: A Straight Sleeve Bearing is suitable for applications where press fitting into a housing bore is the most practical bearing retention method. These are used in crankshaft bearings in petrol and diesel engines, centrifugal pumps and large size electric motors.
