What is Synchronous Pulley?
A synchronous pulley, also known as timing belt pulley, is a precision-engineered wheel with teeth or grooves that mate with timing belts for slip-free power transmission. Unlike friction belts, synchronous drives maintain exact speed ratios without slippage, making them ideal for precision machinery.
- Slip-free operation — maintains exact speed ratio
- Low noise — precision machined teeth ensure smooth engagement
- Low maintenance — no lubrication required
- High torque capacity — efficient power transmission
- Compact design — smaller diameters possible
- Precise positioning — accurate shaft synchronization
- Multiple materials — aluminium, steel, stainless steel, cast iron

FAQs About Synchronous Pulley
- What materials are best recommended for high-speed transmission applications?Aluminium alloy is highly recommended for high-speed synchronous applications due to its lightweight properties. For rotational speeds exceeding 3,000 RPM, Sables recommends dynamic balancing.
- Can I order custom synchronous pulleys with specific bore sizes and configurations?Yes, Sables specializes in OEM/ODM custom timing pulleys with tailored bore diameters, keyways, and set screws. Standard orders require a 10-piece MOQ, while custom designs require 50 pieces.
- What surface treatment options are available for synchronous pulleys?Sables provides diverse surface treatments including ordinary oxidation, hard anodizing, blackening, zinc plating, and nickel plating to prevent corrosion and increase wear resistance.
- What is the difference between Type A, Type B, Type C, and Type D synchronous pulleys?Synchronous pulleys are classified into Type A (standard flange), Type B (back flange), Type C (solid hub), and Type D (deep groove) profiles to accommodate varying flange retention, structural torque, and load capacities.
