Block and Pin Universal joints

Block and Pin or Friction bearings U joints are a universal joint that is slow and needs to be constantly greased so the block doesnt seize up due to lack of grease. The Block and Pin U joints can only run at 1750 RPM, any faster they tend to overheat or excess vibration causes pin wear, leading to premature failure. Replace them with the TSC range of high speed (Up to 7000 rpm), highly flexible (to 45°) and high torque couplings in the same sizes and splines.

Cardan Joints or Universal joints, how about something better

Cardan Joints or Hooke joints? The Cardan joint was invented by Gerolamo Cardano in the 15th century, or at least the gimbal mountings that a modern day Universal joint contains. The Cardan joint gimbals are what we see today in the cross or bearings cross of a universal joint, the actual universal joints themselves were […]

Twin Spring Couplings now offering a T6061 Aluminum constructed version of their spring couplings

Twin Spring couplings flexible coupling replaces universal joints, servo, beam, bellows and elastomeric couplings

We are proud to announce that our 3 Twin Spring Coupling ranges are now also available in T6061 High strength T6 aluminum. We have looked like any good mechanical engineer for ways to save weight but without losing strength or longevity. The artificially aged and precipitation hardening makes this tempered aluminum stronger that 304 Stainless […]

Block and Pin Uni Joints compared to Twin Spring Coupling

Friction bearing U-joints replacement

Block and Pin Universal joints verses Twin Spring Couplings – no maintenance power transmission couplings. In the world of universal joints there are only two versions, the old block and pin and the newer needle bearing u joints. Block and Pin universal joints are over 100 years old Block and Pin u-joints was originally patented […]

Best Industrial power transmission couplings for 2021

Best Industrial power transmission couplings for 2021 The best industrial power transmission couplings for the mass industrial market are broken roughly into these 5 types of couplings, some have subsets as well, the elastomeric couplings have jaw couplings as segment where some people treat them as a category by themselves. These couplings are also constructed […]

Ruland Uni joints – 2 reasons to buy Twin Spring

Mechanical power transmission couplings alternative

Ruland Uni joints Uni joints like all universal joint manufacturers all revolve around the same design, Ruland is no different so all u joints are the same, some of the internal components are different, the hubs can be made stronger but that also increases the price. The universal joint is all the same whether a […]

Lovejoy coupling Uni joints vs Twin Spring Couplings

Lovejoy Uni joints replacements

Lovejoy coupling uni joints The flexible shaft coupling we will discuss today is the universal joint. Originally invented in the 1683 by Robert Hooke the Hooke joint became the universal joint when patented in 1905 by Clarence Spicer. The Spicer joint then with Spicer’s business partner Charles Dana turned into the current day Dana Holdings. […]

New TSC Flexible shaft couplings replaces old uni’s and jaws

Elastomeric couplings

TSC Flexible shaft couplings to replace U joints & Jaw couplings The TSC flexible shaft couplings use a set of springs to be able to flex and transfer torque, this makes them more flexible than a standard u-joint  so there is no need for bearings which require the constant greasing a. to make sure the […]

Bearing failure in Universal joints?

Bearing failure in uni joints TSC300 flexible coupling replaces universal joints, servo, beam, bellows and elastomeric couplings

Bearing Failure in Uni joints, there are only a few option available. The universal joint is one of these fundamental shaft coupling solutions, it’s been used for the past 115 years in the automotive industry and longer in other areas like Industrial and farming. The three-piece design while simple, has always had to been maintained […]

Coupling Solutions for Industrial power transmission coupling failures

Coupling solutions for industrial sector

Coupling solutions replace Lovejoy Universal Joints, Jaw couplings and other couplings. With the 24/7 demands on industrial couplings especially now with the COVID 19 virus meaning less service people and OEM MRO supplies are available, the service manager of these industrial companies have decisions to make. How do I get the most out of the […]

Universal joint replace with the new TSC150

TSC150

Universal joint replacement the new TSC150, a new flexible shaft coupling unit. 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 power transmission coupling to do the job of two different flexible shaft coupling technologies in the one […]
