Product Description
TGL Drum Gear Coupling – Curved Tooth Nylon Sleeve Flexible Coupling
Factory Direct | 45# Steel Hubs | Nylon Elastic Sleeve | H7 Precision Bore | KTR Bowex Replacement | Custom Bores, Keyways, Cones & Inch Sizes
Product Overview
The TGL Drum Gear Coupling is a high‑performance flexible coupling featuring a double‑joint curved tooth (drum gear) design with a nylon elastic sleeve. It is engineered to replace KTR Bowex couplings and is widely used in various mechanical and hydraulic drive systems.
The combination of high‑strength 45# steel hubs and premium nylon sleeves provides maintenance‑free operation, excellent wear resistance, and reliable compensation for axial, radial, and angular misalignments. The curved tooth (drum gear) profile ensures high transmission efficiency and the ability to withstand large torque and load fluctuations. The coupling is assembled by axial insertion, making installation quick and easy.
With H7 precision bore tolerance and DIN6885/1 JS9 keyway tolerance, the TGL coupling delivers accurate, stable power transmission for demanding industrial applications. Custom bores, tapered bores, and inch‑size bores are available upon request.
