YL · YLD · GY · GYS · GYH

Flange Couplings

The most widely used rigid coupling for pump-motor, compressor and gearbox shaft connections. Bolted flanged hubs provide zero-backlash connection that disconnects without axial shaft movement. Available in YL/YLD (GB 5843-86) and GY/GYS/GYH (GB/T 5843-2003), with optional alignment tenon.

Torque: 10 – 100,000 N·m Bore: 10 – 250 mm GB 5843 / GB/T 5843-2003

GT Series

Sleeve Couplings

The GT type sleeve coupling (muff coupling) is a single precision-machined steel cylinder connecting two co-linear shaft ends via keyways. No bolted flanges, no flexible elements. Maintenance-free once installed on accurately aligned shafts.

Torque: 25 – 100,000 N·m Bore: 12 – 200 mm Up to 12,500 rpm

JQ Series

Clamping Couplings

The JQ type split-shell clamping coupling is designed for reactor stirring shaft connections where the shaft is in two sections. The split body wraps from the side — no axial shaft movement required. Standard and non-standard bore sizes available.

Bore: 25 – 160 mm Torque: 90 – 28,000 N·m No keyway required

TS7 · STS7 · TS7C · STS7C

Micro Rigid Couplings

Miniature precision rigid couplings for servo motor, encoder and automation drive shaft connections. Setscrew type (TS7/STS7) for highest speed; clamp type (TS7C/STS7C) for non-marring connection on precision-ground shafts. Aluminum alloy and 316 stainless steel.

OD: 16 – 40 mm Bore: 3 – 20 mm Up to 23,000 rpm Al alloy / 316SS

TS7Z Series

Locking Assembly

The TS7Z locking assembly is a keyless shaft-hub connection using tapered ring compression. No keyway required in shaft or hub. Torque and axial force transmitted entirely through friction. Eliminates keyway stress concentration. 31 bore sizes from 15 mm to 110 mm.

Bore: 15 – 110 mm Torque: 0.126 – 7.20 kN·m No keyway required
