Compression Spring End Types Explained: Fit, Function and Best Practice

Compression springs can be made with different end types. Each one affects how the spring sits, how it carries load and how well it works in the final assembly. There are three common options. Closed and GroundThis is the most widely used compression spring end. The ends are closed and then ground flat so the spring sits square and upright. This is important when accurate load at length is required, for example in valve applications. If the ends are not [...]

Tension Spring End Design: Choosing the Ideal Option for Your Applicationhttps

When designing a tension spring, there are many factors to consider beyond the visual style of the end. Spring rate, how loads are measured at specific lengths, and the tolerances required for the application all influence how the spring will behave in its final assembly. These characteristics work together to create consistent, reliable performance Alongside these core parameters, choosing the right tension spring end type is an equally important step in achieving high-performance spring behaviour. In most tension spring [...]

Giggleswick School Receive Springtelligence Class & Factory Tour

JB Springs’ managing director, Alex Driver, was recently invited to Giggleswick School to give a presentation on all things springs-related to their junior school. The talks were well-received with lots of questions and interest from the students, such as, “Do you think you could go a whole day without using a spring?” (The answer being, it’s very unlikely.) As a follow up to these talks, the Year 6 group recently came to JB Springs for a tour of the [...]
