Spring Plungers - Ball - Slotted

In stock In production

These Spring Plunger with a ball and slotted are used for locating, applying pressure, and lifting off. They have three components: a threaded body, a stainless ball, and a spring mechanism. The spring on the plunger provides the necessary force to keep the plunger in either the extended or retracted position.

The slotted design allows for simple adjustment and exact positioning, allowing one to fine-tune the plunger's extension or retraction to fit individual needs. While the stainless ball is selected for its outstanding corrosion resistance, it ensures the plunger's longevity and reliability even in tough settings. Additionally, the stainless steel ball enables smooth functioning, eliminating friction and wear.

It is simple to install and use and is designed to handle high stress and pressure. The threaded body makes it easy to integrate into existing systems or buildings. It can withstand temperatures up to 250C. These spring plungers are widely utilised in various industries, including medical, optics, orthopaedics, machine and fixture design, lighting equipment, and electronic components, due to their endurance and versatility.

Spring Plungers - Ball End - Smooth

In stock In production

These Spring Plungers with a ball end and a smooth body design are used for locating, applying pressure or lifting off. It is made of three parts: a smooth body, a ball end, and a spring mechanism. They resemble pin-end spring plungers, but the ball end engages more gently and reduces wear and tear on both the workpiece and the plunger.

The plunger's ball end provides a point of contact for accurate engagement and positioning within the application. The collar on the spring plunger serves as a retention function, keeping the plunger securely in place once inserted.

Its smooth body facilitates insertion and is held in place using an interference fit, as well as quick release. It can withstand temperatures of up to 250ºC and is widely utilised in machine and fixture design, electronics, medical, electronics, automotive, and lighting equipment.

Spring Plungers - Ceramic Ball - Slotted

In stock In production

These Spring Plunger with Ceramic Ball and slotted are used for locating, applying pressure, and lifting off. They have three components: a threaded body, a ceramic ball, and a spring mechanism. The spring on the plunger provides the necessary force to keep the plunger in either the extended or retracted position.

The slotted design allows for simple adjustment and exact positioning, allowing one to fine-tune the plunger's extension or retraction to fit individual needs. While the ceramic ball has high hardness, wear, and corrosion resistance, it reduces the possibility of galling or damage to the mating surfaces.

It is simple to install and use and is designed to handle high stress and pressure. The threaded body makes it easy to integrate into existing systems or buildings. It can withstand temperatures up to 250C. These spring plungers are widely utilised in various industries, including medical, optics, orthopaedics, machine and fixture design, lighting equipment, and electronic components, due to their endurance and versatility.

Spring Plungers - Expander Fit

In stock In production

These Expander Fit Spring Plungers are used for positioning, applying pressure, and lifting off. Its unique body design bends to expand, contract, and adjust to bore location tolerances as broad as + 0.2 mm d4.

Its material provides excellent strength in various conditions and temperatures, as well as corrosion resistance, control, and stability. It is quick and easy in production and assembly, and it removes the requirement for the cost of high-accuracy machining and part preparation.

It is recommended that it be used as a single, one-time installation for optimum results since repeated actions of install and uninstall can diminish its capacity to expand into holes with broader tolerances owing to plastic fatigue. It is resistant to temperatures ranging from -30C to +50C. Ideal for applications in plastic moulded components for machine and fixture design, electronics, medical and lighting equipment.

  • Material: Body: Thermoplastic POM, black
  • Ball: Ball bearing steel 1.3505 (100Cr6) hardened or thermoplastic POM, white
  • Spring: Stainless Steel
