TSC150 1/4″ Keyway coupling replacement for industrial coupling users. Replace any flexible shaft coupling, whether its a beam, bellows, Jaw or universal joint with a maintenance free flexible alternative.
Couplings in the industrial sector traditionally are broken into two sectors, the beam/bellows or elastomeric couplings that can only run at angles of 4° or less otherwise they wear out, as they cannot physically flex beyond that, normally they run at 2°.
The other are universal joints which can normally only run at 8° otherwise prematurely wearing the bearings within the propeller shaft of the universal joint, the bearing races will start to wear on the outside which means the ball bearings will become loose and that creates vibration and with continual wear the ball bearings will fail. The bearings need also to be constantly greased otherwise the ball bearings will not have any lubrication, and with them running at high speed the balls will seize in their tracks again leading to bearing failure.
Jaw couplings the spiders wear after use of 1-2° and yokes can crack.
Bellows are only good for 2° before they start to wear.
Beam couplings can only run at 2°
Twin Spring Coupling can run up to 20° without needing to be lubrication, and at low angles of misalignment and comparable high speeds to traditional industrial couplings.
Ball bearings being very precise instruments also need to be contained to ensure infiltration by any foreign contaminants, as things like water, mud, dust or dirt will again cause the ball bearings to seize in their tracks and this means bearing failure. Being used at high speed for long periods of time produces heat and that can cause the ball bearings to seize inside the bearings leading to premature failure.
The other downside to a universal joint are the yokes which the bearings are contained in, the coupling piece of the yokes are quite tough but the section that contains the bearings not so much as they have to hold the bearings, this is a weak point as the bearings are usually less than 2″ across so the machining to contain the bearings is alot smaller than the rest of the yoke, which means the likely of them cracking is that much higher.
Cracking leads to catastrophic failure and replacement of both the yoke and universal joint is assured. This makes it an expensive repair as with the price of the yoke and universal joint, it is usually cheaper just to replace everything, both yokes and the propeller joint.
Twin Spring Coupling is different it replaces the entire U joint, yokes, propeller/cross bearings everything, with a simple one piece design. It can also replace any U joint offroad model as well.
By being a one piece design also means Twin Spring Coupling wont break like the yokes do in traditional uni joints.
Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM.
