Twin Spring Coupling releases its TSC150 flexible coupling

Twin Spring Coupling releases its new TSC150, a hybrid flexible coupling unit that replaces all Universal, Jaw, Beam, Bellows and other flexible couplings.

Pearl River New York - Twin Spring Coupling announced today the release of its 3rd product line the TSC150.

Twin Spring Couplings patented design allows the coupling to do the job of two different coupling technologies in the one, as well as offering a truly maintenance free product as it contains no bearings.

The Twin Spring Coupling TSC150 can handle high speed/low misalignment, while being more flexible than the current flexible couplings due to its dual spring construction. Typically, couplings can only work at +/-6° out of alignment before they start to wear out,

It can also run at lower speeds and higher misalignment like the industry standard universal joint, which requires constant maintenance (greasing and worn bearing replacement).

Adding to that, Twin Spring Coupling’s one-piece design also means no broken yokes which is another area of product failure with universal joints.

The Twin Spring Coupling is torque rated to 150 ft lbs of torque and can run at speeds of up to 3500 RPM at low degrees of misalignment.


A coupling replacement for industrial distribution customers. Replace any flexible coupling, whether its a beam, bellows, Jaw or universal joint with a maintenance free flexible alternative.

Couplings in the industrial sector have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology,

Industrial distribution has evolved but the technology that makes up the couplings has not. Twin Spring Coupling offers something different.

Traditional couplings can only run at angles of 2 degrees or less otherwise you get wear out, universal joints 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 continal 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 4°

Twin Spring Coupling can run at 20° without needing to be lubrication, and at low angles of misalignment, 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. 

​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 usally cheaperr 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.

Designed with no internal components like bearings, means our coupling is truly maintenance free, making it impervious to water, mud, dust, dirt and other contaminants. This saves time and on annual maintenance bills.

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.

Coupling replacement for Spicer, Lovejoy, Beam, Bellows and Jaw couplingsTwin Spring Coupling is the latest in multi directional flexible coupling design, forget your old Uni joints or fragile CV joints. Beam coupling run at high speed but can handle no torque, we can handle both.

Improving on existing coupling technology we provide a number of different versions which allows a 0 to 25° angle of usage

No internal components - No bearings to be constantly lubricated, this saves you time and money.High speed- Runs at up to 6000 RPMTorsionally rigid at low angles of misalignmentScalable - the Twin spring unit can be scaled up or down to suit individual customer requirements.​Customizable - Have a specific form/function the spring/ball settings can be changed to fit most applications. Different shaft types or sizes, no problem, we do all standard sizing.Being made from two counter wound springs means it absorbs shock force without damageSpring design allows greater angle of usage without damaging components​
The patented twin spring design allows for larger angle of usage without deformation with the torque transfer seen with Universal Joints, giving the performance of a Universal joint with the flexibility of a Constant Velocity joint and more.

So how does it work? The design is quite simple, the sets of springs are counterwound so one tightens while the other loosens and visa versa. This allows the coupling to work in both forward and reverse.

The simplicity doesnt end there, the only thing in the center of the coupling is a single ball bearing this allows the coupling to pivot allowing for maximum flexibility, this means no bearings.

Bearings are a constant maintenance issue, they cannot run in harsh environments like water, mud, sand, dust and dirt as any intrusion by any of those elements leads to rapid failure. So no bearings means no constant maintenance or worse replacement.

One piece design - As the product is just hubs and springs the things that can go wrong are greatly reduced, so no cracked yokes or broken propeller joints, no worn out bearings.

Torque - the bigger the better The flexible coupling is powered by the springs, but because it is a pair of springs it effectively is a metal bar, add the ball bearing it turns into a flexible metal bar. So this means more torque and still have the flexibility that would destroy a standard universal or constant velocity joint.

High speed/low speed - Now flexible coupling technology is split into 2 main areas, high speed, low torque, small angle of misalignment and lower speed, higher torque, higher angle of misalignment.

High speed flexible couplings are Beam couplings, elastomeric, bellows couplings and jaw couplings which can run at high speed maintain torsional rigidity but traditionally can only run at a few degrees of misalignment before starting to wear out. Add to that because of that small misalignment angles , the amount of torque these flexible couplings can handle is quite small.  Twin Spring's flexible coupling remains torsionally rigid at lower angles at high speed, with far more torque than say a standard beam coupling, with the added flexibility if needed.

Lower speed couplings like universal joints and constant velocity (CV) joints can work at high torque and larger degrees of misalignment but they have internal components that need to be constantly maintained and the angles of misalignment they can work at is limited as well, as too much will lead to bearing failure. Our coupling can  meet the higher torque demands and the increased flexibility while needing no maintenance as you would have to with using universal joints.

One product multiple uses. Why would you use different products if you didnt need to when one product will do it all, a no maintenance, high speed, high torque, higher angle of misalignment capable flexible coupling.

Three models and counting - To date we have 3 models the TSC150, TSC300 and the TSC500. The TSC150 is capable of handling 150ft lbs of torque and be used at 20°. The TSC300 is capable of handling 300 ft lbs of static torque and operate at angles of  30° the TSC500 can handle 500ft lbs of static torque .  We are looking at what the market demands so bigger or smaller we will be adding more as time goes on, as for splines we can work with you to make any spline you need to fit your equipment.
