The type of end on a compression spring can vary and your choice of end type can greatly influence your design's performance. Several factors come into play such as precision requirements, application context, and cost. This guide will deliver straightforward information on five common end types for compression springs: closed and ground, closed and squared, double closed, general closed, and open ends. For example, high-precision applications might require a closed and ground end. However, if the application isn't as demanding, a simpler, more affordable option could be suitable.

Advantages and Disadvantages - Closed and Ground

Advantages and Disadvantages - Closed and Squared

Advantages and Disadvantages - Double Closed

General Closed

General Closed springs on CoilsDB is the nomenclature used to describe all three closed end types. Searching for this type of spring will yield results from all 3 categories, and is useful if the end type of the design is not particularly critical, which is the case for most non-production level applications.

Advantages and Disadvantages - Open Ends


The compression spring end type that you select has a direct impact on the spring's performance, cost, and suitability for different applications. Each type of end has its unique advantages and disadvantages. Closed and ground ends, for example, are generally more stable but may be more expensive due to the added grinding process. The best choice of spring end type is one that meets your application needs and fits within your budget. The specifics of your engineering applications, including their operational requirements and lifespan, should greatly influence your final selection. Make sure to base your design decisions on the actual requirements of your application to achieve the best outcomes.
