The Timken Fafnir RCJC is a four-bolt square flanged housed unit with eccentric collar locking. The square flange with four mounting bolts provides maximum rigidity and load-carrying capacity for heavy-duty applications — conveyor head shafts, industrial fan bearings, and equipment frames where vibration and thrust loads demand a secure four-point mount.

Cast iron housing with precision-bored seat accepts a Fafnir insert bearing with spherical O.D. for self-alignment up to ±2°. The eccentric collar locks positively against the shaft with a single wrench. Available in shaft sizes from 1-1/4″ through 2-15/16″.

Timken (NYSE: TKR) acquired the Fafnir bearing brand in 2003. Every Fafnir housed unit is factory assembled with a precision insert bearing, ready to mount.
