Frequently Asked Questions

Is this listing for a pair?
No. This caster is sold individually. Select a quantity of two if your machine requires both front casters to be replaced.

Does this caster have a brake?
The OEM description identifies it as a standard 4-inch swivel caster. It is not described as a locking or braking caster.

Will it fit every Century 400 extractor?
No. Century 400 produced many models and configurations. Confirm that your original caster is identified as 040-03 or 8.619-943.0 before ordering.

Should I replace both casters at the same time?
Replacing both may provide more even rolling and machine height when the existing casters have substantial wear, but each caster is sold separately.
