Anti abrasion rubber protective sleeve bushing

A protective sleeve bushing covers a selected contact region so the routed component is separated from an abrasive edge. The protected length should include the point where contact actually occurs, which may sit beyond the visible opening once the assembly is in its final position.

ETOL customizes the dimensions, material, hardness and color. Inspect the route with the mating component installed and identify where it approaches nearby hardware. A sleeve that stops short of that point can leave the vulnerable region exposed despite an apparently tidy entrance.

Fit the bushing without bunching its wall and keep its ends clear of sharp shoulders. After the surrounding supports are secured, check that the protected region has not shifted. During maintenance, look for a localized groove or polished patch that indicates repeated contact. Adjust the route or sleeve length to address the cause instead of rotating the worn area away from view. Keep debris out of the bore during reassembly, and replace rubber with a split wall before the underlying part can touch the hard surface directly.

Material options

Custom rubber compound and color, selected for the contact conditions and required geometry.

Hardness range

30–90 Shore A for rubber. Balance insertion flexibility with support around the opening. Fit the bushing without bunching its wall and keep its ends clear of sharp shoulders.

Custom profile & fit

Keep debris out of the bore during reassembly, and replace rubber with a split wall before the underlying part can touch the hard surface directly.

Assembly considerations

Inspect the route with the mating component installed and identify where it approaches nearby hardware.

Design check

After the surrounding supports are secured, check that the protected region has not shifted.
