Caterpillar Crawler Renovation Completion

Towards the end of last year, our team at JB Springs provided a spring for a vintage 1926 2-ton Caterpillar (CAT) crawler machine; from 1925 to 1928, 8,565 of these were made before being discontinued. Its spec includes a 3-speed gear transmission, 10-inch tracks and a lever that acts as the steering wheel. We recently received some pictures of the fully-renovated crawler – with our spring sitting in pride of place on the starting handle at the front (see [...]

Prestressing: Ensuring high spring quality

Prestressing is a quality-improving process often implemented during the manufacture of springs – mainly compression springs – to enhance their mechanical properties and improve their fatigue life (life cycle). The process involves compression by loading a spring past its elastic limit until it reaches a solid position or a predetermined length (the latter is less common) and plastic deformation occurs. This results in a number of enhancements to the spring including: Increased elastic deformation Increased load capability Improved relaxation [...]

How Fit and Function Affect Spring Longevity

It is fundamental to optimal spring operation and spring longevity that it fits and works freely within the space available. While this may sound obvious, insufficient space for a spring to operate within is a common cause of spring failure. How Fit and Function of Compression Springs Affects Spring Longevity Compression springs often fit over a rod, within a bore, or sometimes both. It is imperative that the spring does not rub on either of these. This will prevent [...]

Diameters of a Compression Spring [Video]

We have created a Springtelligence video which shows you the Wire Diameter (d), Outside Diameter (OD), Inside Diameter (ID), and Mean Diameter (D) of a compression spring. Click the link below to be redirected to our YouTube video, in which these measurements are demonstrated. https://www.youtube.com/watch?v=dGZNPfaSH1k
