Reuland & Trilex Flexible Couplings available from Jealco
Jealco is proud to be a global distributor of Reuland Electric products, offering a wide range of high-performance components including motors, pump adapters, and flexible shaft couplings.
** Last year, Reuland Electric sold its entire inventory of flexible couplings to a select group of trusted distributors, including Jealco. Recently, they also transferred the drawings and manufacturing rights to a Canadian firm named Trilex Fluid Power, Inc. As Jealco is a distributor for Trilex products, you can rest assured that you will continue to have access to the reliable and high-quality flexible couplings, pump housings, and other hydraulic components you have depended on for years. We remain committed to providing these outstanding products to clients around the globe.
How to Select the Correct Coupling for your Application
1 - Determine the Service Factor (SF)
General Rule
LIGHT LOADS - Even or Steady Load – Non-Reversing (SF 1.0)
(Blowers • Centrifugal Pumps • Agitators • Conveyors • Fans)
MODERATE LOADS - Moderate Shock – Uneven Load – Infrequent Reversing (SF 1.5)
(Elevators • Mixers • Machine Tools • Reciprocating Pumps)
HEAVY LOADS - Heavy Shock – Uneven Load – Frequent Reversing (SF 2.0)
(Shaker Conveyors • Crushers • Winches • Presses)
2 - Determine Rated Torque
Rated Torque = (HP x 63000) / RPM x Service Factor
3 - Determine Shaft Size
Remember the shaft size must not exceed the coupling's maximum bore
4 - Select Coupling based on Rated Torque and Shaft Size Parameters
