The SKF medium series angular contact ball bearing with optimized internal design is an open bearing with a 40-degree contact angle, polyamide/nylon cage, normal clearance rating, and Annular Bearing Engineering Committee (ABEC) 1 precision. It supports moderate to heavy one-directional thrust loads and combined radial and thrust loads where the thrust load is predominant. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads. The 40-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads than bearings with a lower contact angle. Due to its optimized internal design, an SKF bearing with an E suffix has a higher load rating than a standard SKF bearing of comparable size. Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has an injection-molded snap-type cage made of glass fiber reinforced polyamide to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). The bearing has a normal axial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. Additionally, the running accuracy and performance levels for this precision bearing meet Annular Bearing Engineers' Committee (ABEC) 1 (ISO P6) standards for a moderate level of precision. ABEC-rated ball bearings are manufactured to tight dimensional tolerances, making them useful in applications that require high accuracy, high rotational speeds, and increased operating efficiency. This angular contact ball bearing is for use in commercial and industrial applications, including pumps and compressors, automotive drives, gearboxes, and printing machines.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. 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 manufactures bearings, seals, and lubrication systems for automotive, OEM, energy, and other and industrial applications. The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
