What these specs mean in practice

Dynamic Load Rating: 9,700 lbf (43.1 kN). Static Load Rating: 6,610 lbf (29.4 kN). Operating Temperature Range: 0 to 212 °F (−18 to 100 °C). Limiting Speed: 4,300 rpm. The eccentric collar has an offset bore that engages a matching offset step on the extended inner ring; rotating the collar against the shaft direction wedges the two eccentrics together and the collar set screw holds the position. Locking is by friction across the full collar bore, so the shaft surface is left unmarked. The spherical outer ring seats in a matching spherical housing bore and takes up initial shaft misalignment.

Interchange guidance

Cross-Reference: SKF YAR 211-202. The SKF YAR family is the equivalent eccentric-collar insert and the -202 suffix is the same 2-1/8 in bore. The set-screw counterpart on this envelope is the UC211-34, which locks on two set screws rather than a collar.
