Key features

• Double-row angular contact ball bearing for limited-space applications supporting radial loads, bidirectional thrust loads, and combined loads
• Ball contact angle of 30 degrees relative to the inner and outer raceways increases thrust load capacity
• Open configuration for lubrication applied in place
• Pressed steel cage evenly spaces balls for reduced friction, vibration, and noise
• Normal axial internal clearance for applications where thermal expansion is not a factor

This SKF 33 A series double-row angular contact ball bearing is an open bearing, and has a 30-degree contact angle, pressed steel cage, and normal clearance rating. It supports radial loads, thrust loads in both directions, and combined loads, and occupies less axial space than a pair of single-row angular contact ball bearings mounted together. Because the two rows of rolling elements are mounted back-to-back, the bearing arrangement is relatively rigid and can accommodate tilting moments. The 33 A series does not have filling slots and has a larger cross section than the 32 A series, making it suitable for heavier loads and slower speeds. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads. The 30-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a standard contact angle of zero degrees. Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibrat
