FAQ

Common questions about this series

Taper-bore HTD timing pulleys (5M/8M/14M): what size range does the table cover?

The table lists 148 standard pulleys across the 5M / 8M / 14M pitches, 28–216 teeth, in steel / cast iron. Bores, keyways, flanges and belt widths are machined to your drawing; other tooth counts and profiles are made to order.

Taper-bore HTD timing pulleys (5M/8M/14M): what is it and when should I use it?

Taper-bore (Taper-Lock bushed) HTD curvilinear timing pulleys, profiles 5M / 8M / 14M; high capacity, keyless quick mounting, accurate centering — for high-power synchronous drives. Pick the profile by the belt you run: HTD curvilinear (3M/5M/8M/14M) for high torque with low noise, imperial trapezoidal (MXL/XL/L/H) for legacy drives, metric T/AT for European machines, and precision GT/BAR profiles when positioning accuracy and low backlash matter. Plain-bore pulleys are machined to your bore and keyway; taper-bore versions mount keyless on a Taper-Lock bush for quick service.

Taper-bore HTD timing pulleys (5M/8M/14M): can I order a size that is not in the table, or just one piece?

Yes. Everything on this page is made to drawing, and the table is only the standard-size subset of the catalogue. Minimum order quantity is one piece — we routinely make single replacement parts for OEMs whose original supplier has discontinued the item. Send a DWG, STEP or PDF drawing (or a sample part): you get a formal quotation within 24 hours after the information is complete, and the first article ships within 30 days of drawing approval, with inspection records.

Taper-bore HTD timing pulleys (5M/8M/14M): what do I need to send to get a quote?

Send the drawing or: tooth profile and pitch (e.g. HTD 5M, AT10, XL), number of teeth, belt width, flange (one side, both or none), bore with tolerance and keyway or Taper-Lock bush size, hub style and material (aluminium, steel, cast iron), surface treatment and quantity. To copy an obsolete pulley, send the worn part — we scan it and identify the profile.
