How to select the pulley and bushing

Check the belt profile, required pulley diameter and number of grooves. Use a type 1108 bushing for this pulley and select its bore to match the shaft diameter. The designation 1108 identifies the bushing type, not the bore diameter. Also consider the shaft design and keyed connection when selecting.

Available from 1 piece. Fulfilment time: up to 48 hours. The bushing is not included in the pulley price; both products are ordered and charged separately.
