SKF GEH20ES2RS Sealed Spherical Plain Bearing 20x42x16x25mm

SKF GEH..ES Series Spherical Plain Bearings: This series is classed as radial spherical plain bearings requiring maintenance. Comprising of sliding contact surfaces of steel against steel these spherical plain bearings are unsealed and require maintenance from time to time in the form of re-lubrication via an annular lubrication groove around its outer and inner rings. They have a wider ball and larger outside diameter than the GE..ES series enabling a higher load capacity and greater tilt angles to be achieved. Dependent on installation design the lubricant may be passed through the housing or spindle directly into the bearing at any point around the groove which has small holes to direct the lubricant onto the mating surfaces. These are metric sized spherical plain bearings. The bearings are manganese phosphated and the sliding contact surface is then treated with a running-in lubricant. This reduces friction and wear during the running-in period. Application: Suitable for heavy static, shock or alternating loads. A characteristic of SKF steel / steel spherical plain bearings is the intentionally fractured outer ring enabling it to be sprung apart to insert the ball, thus care needs to be taken when mounting spherical plain bearings with a fractured or split outer ring, it is essential that the joint is positioned at 90 degrees to the direction of load. Benefits: Re-lubricate-able, heavy duty triple lip sealed.
