Total Height: 84.9 mm (3.343 in). Foot Height: 16.7 mm.

Dynamic Load Rating: 21,600 N (4,850 lbf). Static Load Rating: 11,300 N (2,530 lbf). The eccentric collar locks by wedging an offset collar bore against a matching offset step on the extended inner ring, then holds on its own set screw. That grips across the full collar bore, so it holds against vibration and leaves the shaft surface unmarked.
