V-Belt, Poly-V & Timing Pulleys with Taper Lock Bushes
A belt drive only performs as well as its pulleys. Groove geometry, concentricity and balance decide whether the belt seats correctly, runs cool and reaches its rated life, or slips, wears and vibrates.
Probe supplies wedge and classical V-belt pulleys, Poly-V pulleys and timing pulleys, matched to the belts we supply. Most are bored for Taper Lock bushes, so one pulley fits a range of shaft sizes and can be removed without pullers.
- V-belt grooves to ISO 4183 and DIN 2211
- Poly-V grooves to ISO 9982 / DIN 7867
- Timing profiles from HTD 3M to 14M, T and AT
- Taper Lock bushes from 1008 to 5050
Typical across the range; confirmed per grade or size with the quotation.
Key Benefits
Correct Belt Seating
Grooves machined to the published standard let the belt wedge and grip as designed, which reduces slip, heat and premature belt wear.
Balanced for Speed
Pulleys are balanced to limit vibration at running speed, protecting motor and shaft bearings on high-speed drives.
Fast Fitting
Taper Lock bushes clamp the pulley to the shaft without machining and release it just as easily, cutting change-over time.
Matched to the Belt
Pulleys and belts are specified together as one drive, so profile, pitch and number of grooves are correct from the start.
Pulley Types
Four families covering friction and synchronous belt drives.
Poly-V Pulleys
Multi-rib pulleys for compact, high-speed drives where small diameters and high speed ratios are needed.
