Custom Timing Pulleys
Timing pulleys configured around belt profile, tooth count, shaft interface, load, and positioning needs.
Engineering review
From a controlled drawing or belt-system specification, SINOF reviews pulley geometry and secondary machining requirements.
- Common metric and imperial belt profiles reviewed
- Pilot bore, finished bore, keyway, and clamp concepts
- Flange and hub configurations
- Weight-reduction and balancing requirements evaluated
Materials and precision
Tooth profile, runout, bore, and concentricity requirements are confirmed from the drawing.
- Aluminum alloys, subject to strength review
- Carbon and stainless steels
- Engineering plastics for suitable loads and environments
Customization inputs
- Belt profile, pitch, tooth count, and pulley width
- Hub, flange, bore, keyway, and locking features
- Surface protection and appearance requirements
- Pulley-shaft assembly requirements
Inspection
- Tooth-form and pitch-related checks as specified
- Bore, runout, and concentricity inspection
- Surface-finish and coating verification when required
Frequently asked questions
Which belt information should be provided?
Please provide the belt profile, pitch, width, tooth count, and any preferred belt manufacturer reference, together with shaft and load information.
Can custom bores and hubs be included?
Yes. Bore, keyway, clamp, hub, and flange details can be evaluated as part of the complete pulley drawing.
