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 […]

Lovejoy universal joints are in 2 model types the old block and pin and the newer needle bearing models.
Both still need their center maintained (block constantly greased like the needle bearing) and replaced when worn. The block and pin design can only be used at 1750 RPM and NB model 6000 RPM.
Twin Spring Coupling can run at 7000 rpm, more flexible (up to 45° angular misalignment) and high torque (Up to 6000 In Lbs. of static torque)
One TSC coupling can replace both Lovejoy universal joints.

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 […]

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. […]
Twin Spring Coupling producers of the revolutionary hybrid mechanical power transmission couplings would like to wish you all a happy holiday season and a joyous new year. Here’s hoping that 2021 is a better year for us all. We are going to be making some announcements in early January about a design change for our […]

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 […]

Coupling bearing contaminants – Water, mud, dirt and dust contaminants are one of the many ways that bring uni joints to a halt. Rubber boots, constant greasing and inspections are the usual way used to keep the coupling bearing inside couplings working. That’s part of the ROI but what about the annual cost that adds […]

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 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 […]

The true cost of universal joints are not so simple, a low initial price but with ongoing maintenance means it becomes a lot more expensive Lets face it, its an old technology, 115 years old to be exact, the first use of the word by inventor Robert Hooke in 1676 shows the coupling is far […]
Universal Joint and power transmission couplings So the weather is changing, the short cold days of winter are starting to recede. Now is the time of the service manager starting to his maintenance schedule for plant and equipment. Couplings come into play here as the constant greasing of universal joints and replacement of worn bearings/yokes […]
