Coupling technology to replace universal joints, jaw coupling and other elastomeric couplings.

TSC 500 ft. lbs. (678 n.m) static torque rated

• A new maintenance free alternative to universal joints, jaw coupling and any other mechanical power transmission couplings.
• Larger angle of usage – operational usage of over 25°
• Able to absorb impacts with its twin spring design
• High-low speed, high torque design
• No moving parts, no bearings/spiders so no re-greasing required, and no replacing of worn inserts or bearings.
• Twin springs absorb vibration
• Can run in water, mud, dust and dirt
• Springs allow transfer shock to be absorbed, nullifying “jackhammer” shock and reducing the chance of damage to the powertrain.
• 90+% efficient, torque is absorbed and transferred making it one of the most fuel efficient power coupling units available
• ISO9001 2007 certified manufactured

Twin Spring Coupling TSC 500 is a whole replacement for universal joint in a driveshaft, steering  and any universal joint replacement.

Mechanical Power transmission couplings in any industry have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology, the automobile has evolved but the technology that makes up the universal joint has not. Twin Spring Coupling offers something different.

Universal Joint differences

Traditional universal joints have to be balanced and can only run at angles of 8 degrees or less otherwise you get wear in the bearings within the propeller shaft, the bearing will start to wear, becoming loose and that creates vibration and with continual wear the bearings will fail. No matter whether its a block and pin or needle bearing type uni joint.

The bearings need also to be constantly greased otherwise the bearings will not have any lubrication, and with them running at speed the bearings will seize again leading to bearing failure.

Bearings being very precise instruments especially needle bearings, and they need to be contained to ensure no infiltration by any foreign contaminants, as things like water, mud, dust or dirt as this will cause the bearings to seize and this means joint failure.

​Broken Universal joint yokes

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 a lot 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.

Entire replacement of old uni joint technology

Twin Spring Coupling is different it replaces the entire U joint, yokes, propeller/cross bearings everything, with a simple one piece design.

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.

Jaw coupling alternative

Jaw couplings like the L190, L225 and L276 are big jaw couplings that can take larger capacity when it comes to torque and HP verses the smaller L110 or L150.

They are still fundamentally the same and with increased vibration from larger engines means the spider inserts wear alot quicker than usual. The 1 degree for nitrile rubber inserts means they wear quicker with the larger torque.

Twin Spring Couplings patented dual springs absorb that vibration and are far more flexible than 1 degree, that means a far superior coupling with no wear components like the elastomeric insert of the jaw coupling.

By being a one piece design also means Twin Spring Coupling TSC 500 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.

Speeds of up to 7000 rpm.

Nominal torque of 6000in lbs./495 Kw@7000 rpm/ 500ft lbs.
