Announcing the NEW T-Flex Coupling

Application Range: Coupling sizes available to transmit torque loads from 5 ft/lbs to over 270,000 ft/lbs with shaft capacities ranging from .375" to over 16.00" running from low rpm to over 12,000 rpm.

Coupling Types: Close coupled, Spacer type, Floating shaft, Flywheel, Limited end float, Slide, Brakewheel, Brake disc, and made to order engineered couplings.

Features: Patent pending T-Flex absorbs extreme torsional shock and vibration while accommodating angular, parallel, and axial misalignment without generating thrust loads. T-Flex uniquely combines the stability of a compression type coupling with the safety of a shear coupling. In the event of a lockup, the insert will shear, minimizing the chance of damage to your rotational equipment. No lubrication is required. The rugged polyurethane insert is the only spare part and can be replaced in minutes without having to move the equipment or the shaft hubs. Standard inserts have a temperature range from -60∞ to 200∞ Fahrenheit with a high temperature insert available to over 350∞. The insert is available in a range of hardness to meet most torsional stiffness and torque requirements, and offers high resistance to chemicals and weather. T-Flex can be blind assembled horizontally or vertically from either direction and has a compact size to torque ratio with generous bore capacity. Hubs are available for use with tapered bushings, locking assemblies, shrink discs, finished bored and keyed, taper bored, and spline bored.

How it works: T-Flex close coupled couplings consist of four parts. The Ring Hub, Flex Hub, Insert, and Drive Ring. The Ring Hub and Flex Hub are installed on the shafts with the Drive Ring fitting over the Flex Hub. After coupling alignment, the Insert is wrapped around the Flex Hub engaging the bottom lobes of the Insert. The Drive Ring is then fitted over the Insert engaging the top lobes of the Insert. The Drive Ring is then fastened to the Ring Hub using six alloy steel socket head cap screws with high collar lock washers included with the coupling. The coupling will now transmit torque with silent, smooth reliable operation.

Manufacturing: T-Flex is manufactured in the USA. Standard hubs and rings are machined from solid carbon steel rounds and tubing maintaining tight tolerances which provides great coupling balance. Stainless steels in grades 303, 304 and 316 are also available for corrosive environments and food applications. We also offer a low cost, FDA approved alternative to stainless steel called Melonite Process which turns carbon steel shiny black and prevents wear and corrosion. T-Flex inserts are made from durable custom compounded polyurethane that offers resistance to almost every fluid found in industry today. Using T-Flex ensures dependable, maintenance free torque transmission for your rotational equipment, and comes with support from our knowledgeable staff with over 25 years of experience.
