The 34-8M-85 HTD Timing Pulley delivers heavy-duty synchronous power transmission engineered for wide-format, high-torque systems. Its deep curvilinear 8mm pitch tooth profile ensures maximum engagement to eliminate belt slippage and tooth shear under abrupt mechanical loads.

Product Features & Specifications

Tooth Configuration: 34 precision-machined HTD teeth.
Pitch & Belt Width: High-Torque Drive 8mm pitch optimized for heavy-load 85mm wide timing belts.
Shaft Mounting System: Fully compatible with standard TL 1615 Taper Lock interlocking bushes for simplified keyless installation.
Industrial Build Quality: Rigidly manufactured from high-grade Steel (St) or Cast Iron (GG) to guarantee excellent wear resistance and longevity.
Boring & Keying Readiness: Provided in standard raw stock configuration. Tailor the internal bore sizes directly to your shafts via our In-House Machining Services.
