HTD 2600-5M Elevator Timing Belt 2600mm Length 5-Pitch Synchronous Toothed Belt with Neoprene Rubber Body

HTD 2600‑5M Elevator Door Machine Timing Belt, 2600mm Length 5‑Pitch Synchronous Toothed Belt

HTD 2600‑5M is closed‑loop synchronous timing belt specially used for elevator door operator systems. Pitch 5mm, total pitch length 2600mm, constructed with neoprene rubber body and high‑strength fiberglass tensile cords inside, tooth surface covered with wear‑resistant nylon fabric. The curved‑tooth HTD structure realizes zero‑slip power transmission, featuring low stretch, high wear resistance, low noise and excellent flex fatigue performance. It can withstand frequent reciprocating motion of elevator door opening and closing. Precise tooth dimension matches standard 5M door machine pulleys perfectly. This belt is a direct‑fit replacement for aged, cracked, elongated or broken original belts, widely adopted in elevator maintenance and door‑system renovation projects.

Functions

1. Transmit torque from door motor to door hanger, drive elevator car door for stable opening and closing movement.
2. Synchronize door‑motor rotation with door‑panel travel; zero‑slip tooth design guarantees accurate door position without displacement.
3. Absorb partial vibration during frequent door cycling, reduce running noise for quieter door operation.
4. Solve common door‑fault phenomena: door jitter, abnormal noise, incomplete opening/closing, belt skipping caused by old belt aging or elongation.

Rich Content (Working Environment, Parameters & Installation Notes)

Key specs: Pitch:5 mm; Pitch length:2600 mm; HTD curvilinear tooth profile; Tensile member: fiberglass cord; Body material: neoprene rubberSIT Elatec.... Working temperature:‑20℃ ~ +80℃; Suitable for indoor elevator car‑top environment. Avoid long‑term exposure to oil, corrosive solvent and direct sunlight. Proper belt tension must be adjusted during installation. Too loose causes tooth skipping; excessive tension accelerates belt and bearing wear. Do not bend belt sharply. Regular inspection is required during elevator routine maintenance. Replace the belt in time once crack, hardening, surface peeling or obvious elongation appears. Fit for multiple brands of passenger elevator door‑operator systems.
