Roller recovering is often a practical option when the metal core, shaft end and bearing position remain in good condition while only the rubber layer is worn, aged or cracked. In this case, removing the old covering and applying a new material can reduce replacement cost.
If the core is bent, severely corroded or dimensionally unstable, buying a new roller may be safer. The decision should consider downtime, machining cost, material selection, working load and expected service life.
Before recovering, the roller should be inspected for shaft accuracy, surface bonding condition and usable allowance. A suitable process can restore grip, hardness and surface finish while keeping the original installation interface.
