Pulleys We Manufacture
We machine pulleys for industrial machinery, agricultural equipment, robotics, automotive, and mining applications. Every pulley is engineered for your belt type and speed.
V-Belt Pulleys
Standard A, B, and C profiles. Single and multi-groove designs for power transmission.
Timing Belt Pulleys
HTD, XL, and XXL pitch tooth geometry. Precision machining for synchronous drives.
Flat Belt Pulleys
Smooth or grooved surface for flat belt engagement. Low-cost, high-slip design.
Multi-Groove Pulleys
Multiple parallel V-grooves for increased power transmission capacity.
Idler Pulleys
Smooth bore idler designs for belt tensioning and redirection.
Tensioner Pulleys
Spring-loaded or adjustable tensioner mounts for automatic belt tension.
Cable Pulleys
Smooth bore pulleys for rope or cable guidance and transmission.
Custom Pulley Profiles
Non-standard groove geometry or bore sizes. Engineering support included.
Materials Available for Pulleys
Pulley materials are selected for speed capability, load capacity, and environment.

Pulley Machining FAQ
What pulley types can you manufacture?
We manufacture all major pulley types: V-belt (A, B, C, 3L, 5L profiles), timing belt (HTD, XL, XXL pitches), flat belt (smooth grooved design), multi-groove, idler, tensioner, and cable pulleys. Custom profiles are available for specialty applications. Pulley grooves are machined to industry standards.
What materials are best for high-speed pulleys?
Aluminium 6061-T6 is ideal for high-speed applications — lightweight to minimise inertia and dynamic loads. Steel is used for heavy-duty, low-speed applications where strength is critical. Stainless steel is preferred for corrosive environments. Material choice affects speed capability and load handling.
Can you balance pulleys for precision applications?
Yes. High-speed pulleys are dynamically balanced to ISO 1940 Grade 2.5 or better. Balancing reduces vibration and noise, essential for precision machinery and high-speed systems above 1,500 RPM. Balancing is typically 2–3 business days additional lead time.
What is the typical lead time for custom pulleys?
Simple flat-groove pulleys typically ship within 5–10 business days. Timing belt pulleys with precision tooth geometry may require 10–15 business days. Balanced pulleys add 2–3 days to lead time. Lead time is confirmed in your formal quote.
Can you manufacture pulleys with custom bore sizes?
Yes. Bores are machined to your shaft diameter with keyway, taper lock bushing, or QD bushing mounts. Standard metric and imperial bore sizes are available. Custom bore sizes are cut on-demand. Bore tolerance and keyway profiles are held to DIN standards.
Do you offer prototype pulley production?
Yes. Single-off and prototype pulleys are manufactured with the same precision as production runs. CNC machining makes prototypes and small quantities economical. We recommend prototype testing before full production orders.
