SPA Pulleys · Industrial V-Belt Drive Components
SPA Pulleys for Industrial V-Belt Drives
Select SPA pulleys by groove count, pulley diameter and shaft interface. For replacement or new-drive enquiries, send the marking, drawing or measurable installation data so the pulley and mounting interface can be reviewed together.
Core Range
SPA Pulley Families
Use the series cards as a fast route into the product range. The same family image is used consistently so groove count and mounting information remain the main selection cues.
01
SPA 1-Groove Pulley
Single-groove configurations for compact narrow V-belt drives.
02
SPA 2-Groove Pulley
Two-groove configurations for paired belt transmission layouts.
03
SPA 3-Groove Pulley
Three-groove bodies for wider belt packages and industrial drives.
04
SPA 4-Groove Pulley
Four-groove pulley configurations with taper-bush mounting options.
05
SPA 5-Groove Pulley
Five-groove arrangements for applications requiring a broader belt set.
06
SPA 6-Groove Pulley
Six-groove pulley bodies for higher belt counts and wider drive faces.
B
Pilot & Finished Bore
Direct-bore and pilot-bore options for shaft-specific machining requirements.
T
Taper-Bush Mounting
Pulley and removable bushing interfaces selected around shaft bore and keyway.

Product Showcase
Pulleys, Bushings and Related Drive Components
The site is organized around practical RFQ information rather than visual appearance alone. Pulley profile, groove count, bore or bushing interface, diameter and machine duty should be checked together.
For replacement work, send clear product photos and any readable markings. For new or custom drives, include a drawing or the dimensional and operating inputs available from the machine design.
Selection Inputs
Four Inputs Before You Match a Pulley
A reliable replacement starts with the belt section and mechanical interface, not with a similar-looking casting.
Applications
Industrial Drive Applications
Application context helps define operating duty, available space and maintenance access. Final pulley selection still depends on measurable drive data.
