Description
Listed here is our current standard stock range of pilot bore Pulleys and Bars to suit the Classical XL ( 1/5″) pitch of Timing Belts.
The standard stock range of pulleys are available in 48 tooth sizes in both Aluminium and Steel, and have been designed to drive the 037 (3/8″) wide belt as this is the most popular width of belt used for power transmission drive applications. (It is possible to use the 025 (1/4″) and 031 (5/16″) width belts on these pulleys). Although you can also generate a pulley for any alternative width or for a non-standard stock tooth size by selecting a bar length from the range of 37 tooth sizes we offer.
Alternatively, if you can not find the tooth size you are looking for here. The company does also provides a full manufacturing service to suit any customer’s individual requirement, see our timing pulley manufacturing page for full details.
