Industrial Synchro-Link HTD Timing Belt

The Dayton 1LWA9 Synchro-Link HTD timing belt is a closed-loop power-transmission component built for general industrial drives. It uses a neoprene body with nylon tooth coating and fiberglass reinforcing cord to deliver synchronous motion without slippage. The belt runs on 8 mm pitch and carries 300 teeth across a 2400 mm pitch length.

Replacement For Worn Or Stretched HTD Belts

This belt replaces an existing HTD profile belt of identical pitch, tooth count and 85 mm top width when tension loss, tooth shear or cord fatigue degrades timing accuracy. The jump is worth it when the original belt shows cracking, nylon coating wear or length growth beyond the drive’s take-up range.

Limits Of The 8 mm HTD Standard

The 8 mm HTD pitch caps the minimum pulley diameter and maximum belt speed for a given tooth engagement, so very high-speed or compact drives may exceed the profile’s torque capacity. Operating temperatures must stay between -22 °F and 194 °F; outside this range the neoprene compound hardens or softens, reducing tooth shear strength and cord adhesion.

Questions about this item

What pitch and width do I need for the 2400 mm Synchro-Link belt to fit my pulleys?

The belt uses an 8 mm pitch and is 85 mm wide, matching HTD profile pulleys with 300 teeth.

How do I install the closed-loop fiberglass timing belt without stretching it over flanges?

Slacken the tensioner fully, seat the 300 teeth into the pulley grooves, then tension to the manufacturer's specified deflection for 8 mm pitch.

When should I replace the neoprene belt given the -22 to 194 °F temperature rating?

Inspect regularly for nylon tooth coating wear, fiberglass cord exposure, or cracking; replace immediately if any damage appears.
