PB40L100 Imperial Timing Pulley Pilot Bore
The PB40L100 Imperial Timing Pulley provides smooth, reliable synchronous power transmission for classic machinery and standard industrial assemblies requiring explicit anti-slip mechanics. Utilizing a trapezoidal “L” pitch profile, it delivers consistent positioning capabilities across lightweight and medium-duty machinery networks. Prepped to manage 1.00″ wide imperial timing belts, it comes standard as a plain minimum pilot bore item to allow precise localized machining matched precisely to your shaft specs.
Product Features & Specifications
- Tooth Configuration: 40 precision-milled trapezoidal teeth.
- Pitch & Belt Width: Imperial L-Pitch (0.375″ / 9.525mm tooth spacing) matched with 1.00″ wide synchronous bands.
