Anchor standard FBC type trolley wheels are designed without a ball separator. Because of the ball-to-ball sliding contact and the demand for more chain pull, horsepower requirements are increased.

Anchor retainer type wheel construction is of the Conrad type (single row bearing with balls space apart by a coined, two-piece steel ball separator). This wheel design (with balls separated) causes low friction and requires the least amount of conveyor drive horsepower.

Anchor standard FBC wheels have an extremely deep-grove, fully contoured inner raceway and can operate continuously under heavy (two directional) radial and thrust loads. The construction advantages are:

1. High raceway shoulders for maximum thrust load capacity.
2. Split inner raceway allows for deeper ball path and more balls for maximum load-carrying capability.
3. The raceway rings have a double lock feature. This provides a positive, dual direction lock assuring that the split inner rings will not spread apart. The raceways are case hardened to Rc 58 min. for maximum shock and wear capability.

Precision carbon steel balls hardened and ground to AFBMA standards (chrome steels ball available as an option). No ball retainer or separator required.

Three Inch Wheel: 11 - 13/32" Dia. Balls

Four Inch Wheel: 13 - 1/2" Dia. Balls

Six Inch Wheel: 13 - 3/4" Dia. Balls

Anchor retainer type wheels have a one-piece inner raceway, fully contoured on both sides of the ball for light, continuous thrust and radial load carrying capability. The raceways are case hardened to Rc 58 min. for maximum wear capability.

Precision carbon steel balls hardened and groaned to AFBMA standards (chrome steel balls available on special request).

Six Inch Wheel: 8 - 21/32" Dia. Balls

Two-piece steel construction

Anchor Standard FBC wheels have greater internal raceway clearance for misalignment tolerance and to prevent bearing freeze-up due to dirt contamination, Anchor can provide on less ball, special materials or extra clearance upon request.

Anchor retainer type wheels have normal internal radial fit-up and a ball separator to ensure smooth rolling operation, yet ample clearance for misalignment tolerance.

Anchor standard FBC wheels are designed for temperatures up to 500° F (260° C). For temperature applications above 500° F, Anchor should be informed so that the extra internal clearances can be provided.

Anchor retainer type wheels can be safely used up to 325° F (162° F). This limitation is due to less internal clearance for heat expansion of bearing components.

Anchor Standard FBC wheels can withstand heavy contamination levels (dry or liquid) and operate best with splashproof. Added contamination tolerance can be obtained by using contact lip seals.

Anchor retainer type wheels can withstand moderate contamination levels. Medium level and liquid contaminate can be tolerated by using contact lip seals.

Anchor standard FBC wheels have greater load capacity than retainer type wheels due to the increased number of balls. Specifically designed for maximum load situation, standard FBC wheels can handle peak and continuous radial and thrust loads acting from any direction. They are the best choice for shock and impact loading. Note: In system design, I-beam is the limiting load factor.

Anchor retainer type wheels have the highest load capacity of any available retainer type wheels. Although this capacity is exceeded by full ball complement wheel, Anchor retainer type wheels have ample load capacity for most conveyor systems. Note: In system design, I-Beam is the limiting load factor.
