• Single direction, deep-groove thrust ball bearing for applications that support heavy axial loads in one direction.
• Open bearing for lubrication applied in place.
• Through-hardened chromium steel for durability and resistance to deformity under heavy loads.
• Pressed sheet steel retainer evenly spaces rollers for reduced friction, vibration, and noise.
• Grooved raceways for higher speeds and thrust-bearing capacity than flat washers.

This SKF single-direction, three-piece thrust ball bearing has an Annular Bearing Engineers’ Committee (ABEC)-1 precision rating, grooved races, a 90-degree contact angle, a pressed steel cage, and an open construction. It is suitable for moderate-speed applications that support heavy axial loads in one direction and no radial loads. This deep-groove thrust ball bearing has a three-piece construction with a housing locating washer (ring), a shaft locating washer, and a ball and cage assembly. The washers have grooved raceways that conform to the balls rotating between them, allowing higher speeds and thrust bearing capacity than bearings with flat raceways. The single-row design supports thrust loads in a single direction and tolerates axial deflection, and the open construction allows for the bearing to be lubricated in place. This bearing has a 90-degree contact angle in which the ball and inner and outer raceway contact points are on a plane parallel to the axial load, which enables the bearing to receive high axial force. The balls and washers are made of a low-alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads, and the pressed sheet steel cage prevents the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This bearing is separable so it s more easily than nonseparable bearings because its components can be installed independently. It can be used at operating temperatures from -34 degrees C to 125 C (-30 degrees F to 257 F), and it has an ABEC-1 rating for tight dimensional tolerance, making it useful in applications that require high accuracy and increased operating efficiency. This thrust ball bearing is suitable for applications including machine tool drive shafts, automotive steering gears and clutches, rotary tables, outboard motor propellers, and household appliances.

These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others. SKF Group manufactures bearings and units, seals, mechatronics, and lubrication systems that meet International Organization for Standardization (ISO) 14001 and 9001, and Occupational and Safety Assessment Series (OHSAS) 18001 standards for quality assurance. The company, founded in 1907, is headquartered in Göteborg, Sweden.
