3VX670 Raw-Edge Cogged V-Belt
Executive Product Summary
Engineered to resolve performance challenges in extended center-distance drives, the 3VX670 raw-edge cogged belt prevents sagging, slip, and flex fatigue. Its advanced polychloroprene rubber formulation combined with high-modulus cord reinforcements guarantees long-term dimensional integrity, low thermal buildup, and steady horsepower delivery throughout heavy-duty manufacturing and processing operations.
Key Product Features
- ■Anti-Whipping & Span Stability: Engineered with lateral stiffness to eliminate destructive belt slap, fluttering, and turnover when operating across large pulley center-distances.
- ■Low-Maintenance Tension Retention: High-modulus polyester tensile cords prevent operational elongation, dramatically lowering the frequency of manual drive re-tensioning and machine downtime.
- ■High-Torque Sheave Engagement: Precision-machined raw edge sidewalls maximize frictional contact against pulley grooves, eliminating dynamic slip during sudden load surges.
- ■Thermal & Environmental Resistance: Elastomeric rubber compound withstands continuous ambient heat exposure, oil contact, and ozone degradation without cracking or hardening.
