Start With the Belt Profile, Then Control the Shaft Interface

HTD pulley selection is most reliable when the drive is treated as a system. Confirm the mating HTD profile, tooth count or ratio, belt working width and shaft connection before comparing catalogue rows. The range is organised around 3M, 5M, 8M and 14M straight-bore families, taper-bush configurations, drawing-controlled custom pulleys and matching timing belts.

Browse the Main HTD Pulley Families

Open a family to compare its supported width series, construction references and model-level tables. Tooth counts remain specification rows inside the correct product page so the dimensional context, construction type and ordering code stay together.

Selection sequence

Pitch → Width → Teeth → Mounting → Final Drawing Check

The pitch family identifies the basic synchronous system, but it does not complete the selection. The working width must match the belt arrangement, tooth count must support the required speed relationship and drive geometry, and the shaft connection must match the machine. Replacement projects should also record hub projection, flange arrangement and the belt line before the old pulley is removed.

Keep 3M, 5M, 8M and 14M as Distinct Engineering Families

Nominal pitch is one of the first filters, not a universal capacity rating. Belt construction, width, tooth count, duty, speed and machine geometry still need to be reviewed for the specific drive.

3M

3 mm nominal pitch for compact HTD drive layouts.

5M

5 mm nominal pitch with 09, 15 and 25 width-series pages in this catalogue.

8M

8 mm nominal pitch with 20, 30, 50 and 85 width-series pages.

14M

14 mm nominal pitch with 40, 55, 85, 115 and 170 width-series pages.

Use the Machine Context to Define the RFQ

Application pages help capture duty cycle, environmental conditions, access, guarding and replacement constraints. They do not replace model-specific technical tables.

Custom Bore, Hub, Flange and Inspection Requirements

Use a custom route when the belt-side geometry is known but the shaft interface or installation envelope is not covered by a standard configuration. Send the mating belt/profile, teeth, width, shaft data, hub and flange details, quantity and the drawing revision that controls the part.

Keep the Belt and Pulley in the Same HTD Pitch Family

A matching pitch designation is an essential check, but replacement work should also preserve the complete belt identity, working width and tooth form. The belt page is a companion to the pulley catalogue rather than a substitute for drive sizing.

Manufacturing context

From Tooth Machining to Final Dimensional Review

Manufacturing and inspection requirements should follow the ordered configuration. Special material, tolerance, marking or report requirements belong on the RFQ or drawing before production is released.

Tooth Machining

Keep the tooth family and selected product reference tied to the order.

Bore and hub features follow the released configuration rather than a generic assumption.

Measure, Compare and Specify Before Quotation

The engineering library covers pitch comparison, belt matching, shaft interfaces, replacement measurement, tooth count and material/flange decisions. Use these guides to prepare the input for a model-level quotation instead of copying an isolated dimension from another drive.

Buyer-first catalogue navigation

Choose the Pulley Family Before You Compare Individual Dimensions

An HTD timing pulley enquiry becomes much easier to control when the selection sequence stays consistent. First identify the mating HTD belt family, then working width and tooth count, and only then finish the shaft interface. The site follows that order so product pages, engineering guides and RFQ fields use the same language.

Replacement work

Record the belt marking, tooth count, working face, hub projection, bore or bush and available axial space before the old pulley is removed. A photo from both shaft ends is useful when the original drawing is missing.

New machine design

Start with the required speed relationship, duty, center distance and installation envelope. The catalogue then narrows the pulley geometry; the final shaft connection and controlled dimensions belong on the released drawing.

Mixed-model purchasing

Keep the complete profile, series, tooth count and shaft-interface requirement on every order line. That makes mixed-model orders easier to quote without losing the technical identity of any one pulley.

RFQ readiness

Send Enough Information to Quote the Correct Configuration

For a standard catalogue pulley, send the HTD pitch family, series width, tooth count, shaft or taper-bush information and quantity. For a nonstandard part, add a dimensioned drawing and identify which dimensions are functional. If the existing machine is being repaired, include the belt marking and clear photos of both sides of the old pulley.

Standard parts are normally planned around production quantities. Qualified new-client samples can be reviewed when the configuration and manufacturing route are suitable, while mixed models may be consolidated toward a practical order value. Special materials and special processes follow their own process minimums.
