Product Description
Timken® Fafnir Housed Units
Two-Bolt Flanged Units
Timken Fafnir two-bolt flanged housed units mount to flat surfaces, structural members, and equipment frames using two mounting bolts. The diamond-shaped or oval flange provides a compact mounting footprint ideal for conveyor idlers, fan frames, pillow-block alternatives on vertical surfaces, and applications where a pillow block’s footprint is too large or the mounting orientation requires a flat surface.
Five housing series are available: RCJT (standard), RCJTC (compact), GRFTD (food-grade), VFMST (V-Lock Martin Sure-Tight), and YCJTM (metric). Each accepts a Fafnir insert bearing with spherical O.D. for self-alignment. Select your series and shaft size above.
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.
