Manufacturing Capabilities
Belt Pulley Manufacturing Processes
Machining and surface treatment are selected according to the pulley type, material, belt specification and drawing requirements.
CNC Turning
Machines pulley diameters, faces, hubs and bores to drawing, establishing reference surfaces for subsequent tooth, groove and mounting feature machining.
Tooth & Groove
Machining
Machines timing pulley tooth spaces or V-belt grooves to match the specified belt profile, pitch or section, with geometry controlled to drawing requirements.
Bore & Keyway
Machining
Machines bore fits, keyways, threaded holes and specified bushing interfaces to suit the mating shaft and the mounting arrangement defined in your drawings.
Surface Treatment
Applies material-appropriate finishes or coatings to agreed requirements, accounting for treatment thickness on critical bore fits and belt-contact surfaces.
Customizable materials
Material selection depends on pulley speed, load, weight limits and operating conditions. Aluminum alloy, steel, stainless steel and cast iron can be considered according to your drawings and application requirements.
If you want to customize other special materials, pleasecontact us.

Material Options for Custom Belt Pulleys
Aluminum Alloy
A lightweight option for pulleys where rotating mass matters. Alloy grade and surface treatment are selected according to load, wear and corrosion requirements.
Steel
Suitable for pulleys requiring strength and resistance to mechanical loads. Steel grade, heat treatment and protective finish depend on the drawing and operating conditions.
Stainless Steel
An option for pulleys exposed to moisture or corrosive environments. Grade selection should account for the specific environment, strength requirements and machining needs.
Cast Iron
Commonly used for V-belt pulleys in industrial drives. Grade and pulley construction are selected according to size, operating speed and load requirements.
Customizable Heat treatment
Surface treatments are selected according to pulley material, operating conditions and drawing requirements. Treatment thickness and masking requirements are reviewed for critical bores, mounting features and belt-contact surfaces.
Aluminum Anodizing
Anodizing options for aluminum pulleys are reviewed according to corrosion, wear and appearance requirements. Coating type, thickness and masking requirements are specified to maintain critical bore fits and belt-contact dimensions.
Steel Surface Finishes
Black oxide or plating may be specified for steel pulleys according to the application. Finish selection considers the operating environment and corrosion protection requirements, with treatment thickness accounted for on critical fits and mounting features.
Stainless Steel Passivation
Passivation may be specified for stainless steel pulleys to remove free iron contamination from the surface. The process is reviewed according to the stainless steel grade, operating environment and agreed surface condition requirements.
