Deep groove ball bearing 6320-C4 carries radial and moderate axial loads in a single row of balls running on a bore of 100.0 mm, outside diameter of 215.0 mm and width of 47.0 mm, with net mass of 7.394 kg. The design uses a steel sheet metal cage (JN) and radial internal clearance C4 (Group 4), larger than standard, which compensates for thermal expansion and interference fits during operation. Limiting speed is rated at 4250.0 1/min, with reference speed of 4600.0 1/min. The C4 clearance suits applications where shaft and housing interference fits or elevated operating temperatures would otherwise reduce running clearance to unacceptable levels, keeping the bearing from binding under such conditions. The steel sheet metal cage supports the ball complement without adding a sealing or shielding function, so lubrication must be supplied and maintained externally to match the operating speed range. Dimensionally and constructionally equivalent to SKF 6320/C4, NSK 6320C4 and NTN 6320C4.
