Mining equipment power transmission couplings to replace Universal Joints and jaw couplings.

The Mining industry either below or above ground is tough on all equipment, water, dirt, dust, debris all take their toll on equipment.

Couplings especially take the worst of it, as even though the industry use Spicer U joints offroad rated they still contain delicate internal bearings that will cause them to fail.

Whether it being mining vehicles, submerged pumps, conveyor rollers and more the Universal joint and bearings just cant take the punishment.

These wear parts are all the things that a proper PM (Preventative Maintenance) program is constantly replacing, but even with a program in place any of these parts can fail early due to their construction.

Twin Spring’s Coupling are lubricated and encased at time of manufacture which means no water, dirt, dust or debris can enter the coupling resulting in early failure.

The encasement also means it can be used in hazardous environments, ie areas of gas build up

Being made up of a set of counter wound springs means it is multi directional, so it will work on almost all equipment.

No maintenance means less down time with mining equipment waiting to be repaired or out of service to be maintained both costs money.

By having no internal components that will not fail due to water impregnation, as is common with universal joints the Twin Spring Coupling’s design allows for longer running, no maintenance and that adds up to money saved, from improved downtime of mining equipment to reduction in spare parts inventory needed to be on hand in case of failure.

Can be used in conjunction with an impact coupler, roof bolting systems etc.

Available in PTO, Keyway and various spline options, connection sizes range from 1/2″ through to 1 3/4″

Industrial universal joints

TSC300 Mining coupling


TSC300 mine - 300 ft lb replacement for universal joint in any piece of equipment, whether it be vehicle, conveyor or pump. Replace a century old three piece system with a simple maintenance free one piece design. Couplings in the mining 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. 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. Replaces Spicer, Lovejoy, Moog, Weasler, Walterscheid, Neapco, SKF and Belden couplings and more

Jaw Couplings

TSC500 Mine coupling


TSC500 mine (500 ft [email protected]) replaces universal joint and other flexible couplings in any driveshaft, steering and any other power transmission requirement you may have.

Flexible couplings in the mining industry have a number of issues to contend with, annual maintenance, hostile work environment including water, dust and debris, lost productivity due to unscheduled coupling failure. Twin Spring Couplings simple 1 piece design replaces the entire U joint, yokes, propeller/cross bearings everything, with a simple one piece design. Uses include
  • Conveyor belts
  • Mining vehicles
  • Pumps
  • Plant Equipment
  • Grinders
Replaces Spicer, Lovejoy, Neapco, GMB, Moog, Rockwell , Weasler, Walterscheid and Bondioli couplings.
