Timing Pulleys & Belts

Put the pulley at the center of your belt-drive request. Coordinate bore, profile and machining details with the matching belt.

Drawing-based Pulley
  • Drawing number and revision
  • Tooth and bore geometry
  • Material and finish
  • Quantity and inspection requirements

An updated drawing must identify the revision that governs the quotation. Mark superseded files clearly.

Keyless Timing Pulleys
  • Tooth profile and count
  • Belt width
  • Shaft diameter and connection model
  • Hub and axial envelope

Keyless does not identify one universal mounting interface. Specify the approved locking arrangement or provide a drawing.

Timing Drive Idlers
  • Specified idler model or drawing
  • Contact-surface requirement
  • Width and flange dimensions
  • Bearing and mounting interface

A smooth idler and a toothed idler are different requirements. Use the belt-layout drawing to identify the intended position.

Open-ended Timing Belts
  • Profile and pitch
  • Width and material reference
  • Open length or joined requirement
  • Length and quantity per item

Open-ended, cut-length and joined-belt requests must remain distinct. State the required supplied form explicitly.

Supply routes

Supply by specified model, China-made production or drawing.

For brand distribution, China-made components and drawing-based parts, origin, specifications and supply terms are confirmed by item.

PRODUCT FORMS

A clear view of the available forms.

For this product family, tooth form, shaft connection and machining details are coordinated with the matching belt. Standard supply and drawing-based pulley work can be handled in one package.

INTERFACE & SELECTION

The details that connect the assembly.

Tooth system compatibility

Identical pitch values do not establish interchangeable tooth profiles. Belt and pulley identities are evaluated as a pair.

Hub and shaft interface

Machining requirements connect the bore, keyway and axial retention to the actual shaft and its assembly sequence.

Belt path and loading

Centre distance, wrap, tensioning and operating duty influence the suitability of the complete pulley-and-belt combination.

INTEGRATED SUPPLY

Connected parts in one component list.

Shaft support

Bearing and housing arrangements are connected to the belt-driven shaft and its loading.

Bearings

Drive assembly

Motor shaft geometry, pulley mounting and transmission arrangement are handled in the same component list.

RFQ information

A complete model is enough to begin. Partial information is welcome too.

A model, photo, drawing or BOM can start the discussion; brand, quantity and critical interfaces can be clarified by item.
