Decoding the designation

GN — Fafnir ball bearing insert with a spherical outer ring and a narrow inner ring, the short-hub form of the G insert range.

104 — the size code in the GN range; the shaft size is 1-1/4 in.

K — the eccentric locking collar seat on the extended inner ring.

LL — a seal on each face.

COL — the locking collar itself, supplied with the insert.

What these specs mean in practice

The spherical outside diameter seats in a matching housing socket and lets the insert swivel, so the bearing takes up shaft misalignment on a bolted-in-place pillow block or flange without edge-loading the raceways. The eccentric locking collar grips the shaft by cam action when it is turned against the inner ring and set with its grub screw, which holds the insert on a plain drawn shaft with no shoulder, threaded nut or keyway. Seals on both faces hold grease in and keep washdown and airborne dust out, which is what suits this execution to conveyor, fan and agricultural drive positions.

Unit Quantity: 1 Pc. One insert with its locking collar.
