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 […]

Uni joints or universal joints are a 3 piece flexible coupling. Made up of 2 hubs and a center bearings. The bearings need to be constantly maintained and replaced when worn.
Twin Spring Coupling offers a one piece coupling, that offers high speed (7000 rpm) high torque (up to 500ft lbs. max static torque) and high flexibility (Up to 45° angular misalignment)
A one piece coupling means a longer lasting coupling Available in shaft sizes up to 1 3/4″
Weasler PTO couplings Weasler PTO couplings are a brand well known in the agriculture u-joints, Walterscheid and Bondioli as well . They all rely on the underlying universal joint technology to work. The only real difference is the Weasler PTO couplings are made using larger uni joints, revolving around technology like the Spicer 1310/ Spicer […]

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 […]

Spicer Universal joints vs a bearing free, flexible alternative. Spicer Uni joints design are broken into two different offerings With 2 models both use needle bearing in the bearing cross, one is greaseable, the other is not as it is called a permanently greased. The universal joint is all the same whether a friction bearing […]

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. […]

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 […]
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 […]
