Description
This deep groove ball bearing carries radial load on a single row of balls, running with a steel sheet metal cage marked JN that keeps the ball set guided through the rotation cycle. Bore diameter is 105.0 mm, outside diameter 225.0 mm, width 49.0 mm, giving the housing and shaft seat dimensions for fitting. Net mass is 8.7 kg. Limiting speed is rated at 4050.0 1/min, with a reference speed of 4450.0 1/min. The C4 internal clearance (Group 4) provides a wider radial play than standard, which compensates for thermal expansion and interference fit on the shaft during operation. Bore type Z indicates the bore tolerance applied at manufacture. As an open design, lubrication must be supplied externally and the mounting environment kept clean. Dimensionally and constructionally equivalent references are SKF 6321/C4, NSK 6321C4, and NTN 6321C4.
