Pilot Bore Metric Timing Bars For 2.5mm Pitch Belts - T2.5-24

Pilot Bore Metric Synchronous Timing Bars

Challenge manufacture a range of metric synchronous timing bars from aluminium. Standard lengths are available from 75mm up to 160mm covering the belt ranges T2.5, T5, T10, AT5 and AT10.

Timing bars that are not included within our standard range can be manufactured to customers requirements. Options include overall timing bar dimensions, bore details (i.e. fitting bearings), number of teeth or materials (such as Steel).

Standard and custom - V and Timing Belt Pulleys
To complement our wide range of belts, we also manufacture and supply a range of standard and bespoke pulleys for our V belts and Timing belts. Manufactured from cast iron or steel, our pulley grooves are machine cut for accuracy and also statically or dynamically balanced (depending upon their size) to grade Q6.3 or better giving peripheral (rim) speeds of up to 40m/s.

Standard Features
The complete range of pulleys available from Challenge are manufactured from high grade close grain GG25 grey cast iron or steel before being phosphated for protection. Metric timing pulleys are also available from lightweight aluminium with a natural finish.

Shaft fixing option vary due to the large range of sizes and materials available, but as standard the range of pulleys come with either a taper bore, pilot bore or both types of bores.

V Belt Pulleys
With high quality machined groves and availability from nearly 20 official locations around world, these cost effective and readily available range of pulleys have proven themselves countless times over the last 40 years. Coupled with our wide range of Shaft Mounted Speed Reducers, they offer a reliable method of reducing motor speeds, which has become an industry standard.

Available to suit both wedge and classical belts to ISO 4184. Groove dimensions conform to ISO 4183 for both eccentricity of outside diameter to bore and groove side wobble tolerance.

All pulleys are available with a taper bore to suit the Challenge range of stock taper bushes although pilot and QD bush bore pulleys can also be manufactured.

A wide range of non-standard styles and sizes up to a diameter of 2400mm can be produced.

PV pulleys are also available for sections J, K and L

Timing Belt Pulleys
Working in precision applications globally, our range of timing belts and corresponding pulleys have been developed around the industries that we supply daily. With our ability to manufacture special pulleys or offer light weight solutions from aluminium we can offer a solution for a vast array of precision drive systems.

Timing belt pulleys are available for the standard Classical, HTD Profile and Metric belts. Classical L and H pulleys are available with a taper bore as are 5M, 8M and 14M HTD Profile pulleys. All other sizes are available in pilot bore including the complete range of Metric timing pulleys. If you require a taper bore for a Metric or large Classical pulley, then these can often be manufactured to order.
