22-8M-20 HTD Timing Pulley c/w TL 1008 Taper Lock Bush Bore
The compact 22-8M-20 HTD Timing Pulley delivers high-torque, synchronous power transmission inside tight structural drive envelopes. Featuring a precision curvilinear 8M profile with an 8mm tooth pitch, it distributes radial loads evenly across 20mm wide timing belts to prevent slipping and tooth shear during sudden startups. The hub comes pre-machined to accept a standard TL 1008 Taper Lock bush, ensuring a balanced, keyless clamping connection directly onto your drive shaft.
Product Features & Specifications
- Tooth Configuration: 22 precision-machined HTD teeth.
- Pitch & Belt Width: High-Torque Drive 8mm pitch optimized for standard 20mm wide timing belts.
- Shaft Clamping System: Engineered to mount with standard TL 1008 Taper Lock interlocking bushes.
- Industrial Build Quality: Rigidly manufactured from high-grade Steel (St) or premium Cast Iron (GG) to ensure high durability and wear resistance.
- Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
