Measure the center-to-center distance between your two pulleys, then calculate: Perimeter ≈ 2 × C + π × (D1 + D2) / 2, where D1 and D2 are the pulley pitch diameters. For example, a 2520mm (≈99.2") belt typically suits a drive with roughly 390–420mm center distance using standard HTD3M pulleys. Always verify against your machine's spec sheet. If you're replacing an existing belt, measure the old belt's perimeter directly.

A 30mm wide HTD3M polyurethane belt with steel wire cores generally handles higher tangential loads than rubber equivalents of the same width — typically in the range of several hundred Newtons of working tension. Exact capacity depends on pulley tooth count, speed, and operating temperature. Contact us to confirm suitability for your specific application.

Polyurethane is generally more resistant to oils, mild chemicals, and moisture than standard neoprene rubber belts. However, prolonged UV exposure or immersion in water is not recommended. For outdoor or wash-down environments, verify operating conditions with us before ordering.

Yes. This belt follows the HTD3M tooth profile standard — 3mm pitch, rounded tooth form — and is compatible with any HTD3M pulley of the appropriate width (30mm or wider flanged pulleys). It is not interchangeable with GT2, MXL, T5, or other tooth profiles. Always confirm your pulley's tooth profile before ordering.

Polyurethane belts with steel wire tensile cords offer lower elongation under load, better dimensional stability over time, and improved resistance to oils and abrasion compared to standard rubber belts. This makes them a preferred choice for precision motion applications like CNC routers, laser cutters, and automated conveyor systems where maintaining exact pitch position matters.

Most single-axis drives require 1 belt. If your machine uses two parallel drive axes (e.g., a dual-motor gantry CNC or dual-belt conveyor), select the 2 pcs option to ensure both belts are from the same production batch for consistent performance and matched stretch characteristics.

This belt uses the HTD3M profile: 3mm pitch (tooth-to-tooth distance measured along the pitch line), with a rounded, curvilinear tooth form designed for high-torque, low-backlash power transmission. The "3M" designation means 3mm pitch in the HTD (High Torque Drive) family — distinct from the older trapezoidal tooth profiles like MXL or XL.
