RTU — Fafnir take-up mounted bearing, cast iron side-mount frame carrying an eccentric locking collar insert.
1 — shaft size, 1 in.
G1100KRRB — the wide inner ring insert bearing fitted in the frame, with its extended inner ring and eccentric collar seat.
Dynamic Load Rating: 15,500 N (3,490 lbf). Static Load Rating: 7,800 N (1,750 lbf). Item Weight: 3.3 lb (1.50 kg).
A take-up unit carries the bearing in a frame that slides along a machined slot, so the shaft centre can be moved to tension a belt or a chain and then locked. The eccentric collar grips the shaft by rotating against the extended inner ring in the direction of shaft rotation, which needs no shaft machining and no setscrew flat. The shroud seal shields the ball track from conveyor dust and washdown carryover.
Unit Quantity: 1 Pc. One complete take-up unit, cast iron frame, insert bearing, eccentric collar and seals assembled.
