8 mm Chain Tensioner Roller Set

This pair of black chain tensioner rollers fits an 8 mm inner diameter and 36 mm outer diameter. They are designed for dirt pit bikes, street motorcycles, ATVs and similar off-road vehicles. The rubber and metal construction is waterproof and hard-wearing for regular riding conditions.

Installation Notes

Each roller arrives with duty bearings fitted, so no separate bearing press is needed. The supplier states installation is easy but recommends professional fitting to ensure correct chain alignment. A manual measurement tolerance of 0-1 inch is noted, so verify the 36 mm length and .31 inch bore before mounting.

Who Should Buy

Riders needing a direct replacement pair for worn chain guide pulleys on compatible motorcycles or ATVs will find these suitable. Buyers who require a different bore size, a single roller, or a coloured variant other than black should look at other options.

Questions about this item

How can I confirm the 8mm inner diameter rollers are rotating freely after installation?

Spin each roller by hand; both should turn smoothly without binding or side-to-side wobble on the 36mm shaft.

The box lists 2 pcs chain pulley roller slider — are mounting bolts or spacers included?

Only the two black rubber-and-metal rollers are supplied; any bolts, washers or spacers must be sourced separately.

Which roller size matches a 36mm outside diameter and 8mm bore for my dirt pit bike?

Choose the 36mm total length, 8mm inner diameter, 36mm outside diameter version — the only size in this pack.
