SKF 7020 ACDGA/P4A Spindle Bearing

SKF 7020 ACDGA/P4A - precision non-disassemblable single-row angular contact ball bearing with a contact angle of 25°, featuring a lightweight phenolic resin cage reinforced with textile fabric guided by the outer ring, universally pairable with light preload. The bearing can only transmit axial loads in 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 axial position adjustment relative to the second bearing, which provides axial guidance in the opposite direction. Bearings for universal pairing are mounted in pairs and are manufactured to achieve a predetermined internal clearance or preload, or uniform load distribution without the use of shims when assembled for axial load in one direction (i.e., in tandem) or for axial loads in both directions (i.e., back-to-back in "O" or face-to-face in "X").
