Dayton 1DHV1 Timing Belt 560-8M-20

This Dayton 1DHV1 is a Synchro-Link curvilinear timing belt built for general industrial power transmission. It uses a neoprene body with a nylon tooth coating and fiberglass reinforcing cords for strength. The closed-loop design has 70 teeth on an 8 mm pitch, giving a 560 mm pitch length and 20 mm top width. It suits machinery that requires precise synchronous drive.

Sustained load behaviour

The belt is rated for continuous operation between -22 °F and 194 °F, with heat-resistant and oil-resistant properties to maintain grip and dimensional stability under prolonged thermal and chemical exposure. Fiberglass cords resist stretch so tension remains consistent over long runs. The nylon coating reduces wear on tooth faces during extended duty cycles.

Installation and common issues

Installation requires matching the 8 mm pitch and 70 tooth count to the driven and driver pulleys, then tensioning to the equipment manufacturer's specification. Common problems include misaligned pulleys that cause edge wear, incorrect tension that leads to premature cord fatigue or tooth jump, and exposure to chemicals beyond the stated oil resistance that degrades the neoprene body.

Questions about this item

How much heat can the 194 Degrees F maximum operating temperature handle during continuous daily operation?

The neoprene belt with nylon coating is rated for continuous use up to 194 Degrees F, with a minimum operating temperature of -22 Degrees F.

What pulley pitch and tooth count must my drive system have to match this 560 mm pitch length and 70 teeth?

The belt uses an 8 mm pitch with 70 teeth, so the mating pulleys must be 8M profile with matching tooth engagement for proper meshing.

Will the fiberglass reinforcing cord and HTD trade size work with older HTD pulleys I already have?

Yes, the HTD trade size and curvilinear tooth profile are designed for standard HTD pulleys, and the fiberglass cord maintains dimensional stability under load.
