Item # T4-3.5, T-Series Spacer Couplings On U.S. Tsubaki Inc.

The T-Series uniquely transmits torque while accommodating misalignment without generating reactionary loads, increasing bearing life. Torque transmission capabilities up to 2,041,000 in.-lbs and shaft diameters to 20.00”. Coupling types range from close coupled to long span floating shaft couplings. The bolt on ring makes the T-Series a great fit for bidirectional and reversing applications. The T- Series has no metal-to-metal contact and in the event of a lock up, the insert will shear without damaging the connected equipment. Lubrication free and access to the insert without moving the connected equipment means replacing inserts with ease in minutes vs hours compared to lubricated coupling maintenance.

T-Series absorbs extreme torsional shock and vibration while accommodating angular, parallel, and axial misalignment without generating reactionary loads, which significantly increases bearing life.
No lubrication is required.
Standard inserts have a temperature range from -60° to 250° Fahrenheit with high temperature inserts available up to 350°.
The inserts are available in a range of hardness to meet most torsional stiffness and torque requirements, and offers very high resistance to chemicals.
T-Series couplings are suitable for blind assembly, horizontal or vertical, reversing, and stop/start applications.
The compact size to torque ratio with generous bore capacity allows proper sizing.
Hubs are available for use with tapered bushings, Iock assemblies, shrink discs, finished bored and keyed, taper bored, and spline bored.
OnyxShield™ couplings are available for enhanced corrosion and wear resistance.
