1270-5M-15 Metric Curved Tooth Timing Belt

1270-5M-15 Metric Curved Tooth Timing Belt (1270-5M-15 Metric Curved Tooth Timing Belt)

The 1270-5M-15 Metric Curved Tooth Timing Belt is an industrial-grade synchronous power transmission belt engineered for high-torque, non-slip mechanical drives. Featuring an advanced curvilinear (HTD) tooth profile, the 1270-5M-15 ensures smooth tooth engagement, minimal backlash, and precise timing synchronization across high-speed and heavy-load applications without the stretch, slippage, or lubrication requirements of roller chains or traditional trapezoidal belts.

Key Features & Performance Benefits

• Curvilinear HTD Tooth Profile: Distributes tooth shear stresses uniformly across the tooth root to resist tooth ratcheting, reduce vibration, and deliver significantly quieter operation.
• High-Tensile Fiberglass Cords: Helically wound fiberglass reinforcement cords provide high tensile strength and dimensional stability with virtually zero elongation, eliminating retensioning maintenance.
• Wear-Resistant Nylon Fabric Facing: Low-friction, durable woven nylon fabric over the teeth shields against abrasive wear and extends service life in harsh operating environments.
• Oil & Heat Resistant Compound: High-grade chloroprene (neoprene) backing protects tensile cords against ambient dirt, grease, moderate oils, and frictional heat buildup.
• Standardized Interchangeability: Engineered in strict compliance with ISO 13050 and DIN 7721 synchronous drive standards.
