Racks / Sprockets / Couplings / Timing Pulleys

齿条/链轮/联轴器/同步带轮

Gyan Drive offers a full range of power transmission components including racks, sprockets, couplings, and timing pulleys. Racks provide linear motion transmission. Sprockets are compatible with ANSI/DIN/ISO standard chains. Couplings include jaw, diaphragm, universal, and rigid types. Timing pulleys support HTD (curvilinear), trapezoidal, STD, and RPP tooth profiles. Chains, belts, and accessories also available for one-stop procurement.
