SKF 7020 CDGA/P4A Spindle Bearing

SKF 7020 CDGA/P4A - precision non-disassemblable single-row angular contact ball bearing with a contact angle of 15°, featuring a lightweight phenolic resin cage reinforced with textile fabric guided by the outer ring, universally pairable with light preload. The bearing can transmit axial loads in only one direction, which is why it is typically set against a second bearing. The internal clearance of single-row angular contact ball bearings is achieved only after installation and depends on the adjustment of the axial position relative to the second bearing, which provides axial guidance in the opposite direction. Bearings for universal pairing are mounted in pairs and are manufactured so that when assembled for axial load in one direction (i.e., in tandem) or for axial load in both directions (i.e., back-to-back in "O" or face-to-face in "X"), a predetermined internal clearance or preload or uniform load distribution is achieved without the use of shims.
