Advantages and Disadvantages of Jaw Couplings in Industrial Applications

Jaw couplings

Advantages and Disadvantages of Jaw Couplings in Industrial Applications Introduction In the realm of industrial applications, jaw couplings have gained popularity for their ability to transmit torque while compensating for misalignment. These mechanical devices consist of two hubs connected by an elastomer element, which provides flexibility and dampens vibrations. In this article, we will explore […]

Jaw Couplings: The Unsung Heroes of Power Transmission

Jaw couplings

Jaw Couplings: The Unsung Heroes of Power Transmission As an industrial business owner, I’ve come to rely on jaw couplings as the unsung heroes of my power transmission systems. These robust and versatile components have played a crucial role in keeping my machinery running smoothly and efficiently, day in and day out. Over the years, […]

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 […]

Covid 19 and coupling maintenance

Covid 19 means less people means less coupling maintenance means more breakdowns In times of crisis like we are living through now we have less people to do the work that needs to be done as most people are at home trying to steer clear of contracting or worse spreading the Covid 19 virus. This […]

Twin Spring Coupling products now ISO9001:2015 standard

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

Twin Spring Coupling does a QA system resolve fundamental design flaws like that in a universal joint? Twin Spring Coupling with its alliance with Yuanlu announces all our products are now ISO9001 QA certified. The certification is important especially after we have seen the universal joint/yoke failures in the Ford range of Transit vans and […]

Couplings – How old power transmission couplings cant last in the era of Industry 4.0 and Amazon

Universal joints replacement

Power transmission couplings – Universal Joints, jaw type couplings, beam couplings, bellows couplings and elastomeric couplings all suffer from the same design flaws. We have always used them, they are the only things we use, we just accept the annual maintenance cost and failure rate. A common story from manufacturers and distributors, the power transmission […]
