Key specifications

Available sizes

Model codes are the supplier's part numbers; the SKU is the AIMS part number. Dimensions are in inches with millimetres in brackets, as published in the supplier's catalogue.

Selecting the right option

Match the idler to the belt it runs on (V-belt section), then the outside diameter, the bore or bolt size, and the width the belt needs.

The model codes and dimensions for each size are in the sizes table. If you have the old idler, match its model code or measure the outside diameter, bore and width.

Pulley width (W) is the overall width of the pulley.

If the size you need is not listed, send AIMS the outside diameter, bore and belt type and we will check what is available.

The catalogue page for this product, with its dimension drawing, can be downloaded from the Catalogue section of this page. Dimensions are as published in the supplier's catalogue.

Fitting and use

Mount the idler on a bolt that matches the bore, or the reduction bush where one is fitted, and clamp through the bush or inner ring only so the pulley rim turns freely on the bearing.

Line the idler up with the belt path, keep the running face clean and free of burrs, and set belt tension to the drive manufacturer's figure.

The bearing is sealed and lubricated at the factory. Keep water, grit and solvents away from the seals, and replace the idler if the bearing runs rough or noisy.
