Spring plungers for fitness equipment

Spring plungers for fitness equipment are essential to ensure quick, safe, and repeatable adjustments on machines subject to frequent use, such as those found in gyms. These components allow immediate locking and unlocking of manual mechanical systems, ensuring maximum holding power with minimal effort from the user.

In fitness equipment – such as multifunction machines, isotonic machines, adjustable benches, exercise bikes, and other training machines – spring plungers make it possible to quickly adapt settings to different user needs. The spring mechanism reduces component wear, improves the smoothness of adjustments, and ensures maximum safety even in the presence of repeated movements and variable loads.

Gamm offers a complete range of spring plungers for fitness equipment, designed to deliver high mechanical performance, long service life, and ease of use even in intensive applications.

The metal part of the spring plungers is available in several versions:

• black-oxide steel, for high strength and a dark matte design;
• zinc-plated steel, a versatile solution suitable for most applications;
• stainless steel, ensuring maximum corrosion resistance and a polished finish.

The knurled knobs made of glass fiber reinforced thermoplastic, with a matte sandblasted (MAT) finish, provide an ergonomic grip and high wear resistance. Alternatively, versions with a flag handle (lever) in black-oxide or stainless steel are available, designed for those who require an even more immediate and robust control.

The standard dimensions of spring plungers for fitness equipment range from M6 to M20 bodies, all available ex stock to ensure fast responses to production needs.

For specific applications, custom color options for thermoplastic components are available, with a choice of the indicated RAL colors or special variants on request.
