Pneumatic cylinder piston for tyre changer, Ø200 mm – M18 thread, with seal set

Complete cylinder piston for a tyre changer with an outer diameter of 200 mm, featuring a central M18 thread and factory-fitted sealing rings. The radially ribbed aluminium casting operates within the pneumatic cylinder and transmits air pressure to the working rod – the machine’s full clamping force depends on its condition.

Ready for installation. The piston is supplied with seals and a guide ring already fitted – you do not need to buy a repair kit or reuse old seals. Simply screw it onto the rod and fit it into the cylinder.

When should the piston in a tyre changer’s cylinder be replaced?

A worn seal allows air to leak through to the other side of the piston – the force decreases, the movement becomes ‘soft’, and the compressor kicks in more often than it should. The most common symptoms:

a noticeable drop in clamping force when working with a tyre,
slow, jerky or uneven movement of the cylinder,
a hissing sound of air escaping from the cylinder or the valve vent,
spontaneous sinking after being positioned,
visible wear, cracks or deformation of the old piston upon removal.

From workshop experience: before fitting a new piston, check the cylinder bore. Longitudinal scratches will destroy the new seal within a few weeks and you’ll be back to square one. Coat the seals and the inside of the cylinder with pneumatic grease – oil-based greases cause rubber to swell. Slide the piston in evenly, without skewing it, so as not to pinch the ring.

How do you choose a Ø200 mm piston with an M18 thread for your machine?

Before purchasing, compare three things with the old part: the piston’s outer diameter (it must match the cylinder’s inner diameter), the rod thread – in this case M18 – and the ring clearance. If you’re dismantling the cylinder for the first time, it’s worth checking the condition of the piston rod and the cover seal straight away; replacing everything whilst the machine is open saves you a second downtime.

Frequently Asked Questions

What cables do I need for my two-post lift?

Check the rope termination. If there are any markings on it, the total rope length is very often indicated as well, e.g., L8920. This means the rope length is 8.92 m.

Additionally, to correctly select the rope, you need to provide the following technical parameters:

Rope diameter – measured in the middle section (e.g., 8 mm, 9 mm or 10 mm)
Thread – diameter (e.g., M16)
Thread – length – length of the threaded section (e.g., 14 cm)

The drawing below shows the parameters that must be provided when ordering the rope:
Ropes parameter

What is my machine's model?

Find the nameplate on the device – it usually contains key information, such as:
- Manufacturer
- Device model
- Year of manufacture
- Serial number
If you cannot find the nameplate and do not have the technical documentation, selecting parts based on the model may be difficult. In this situation, we recommend searching for parts by category, photos, and dimensions, which often allows you to precisely match the correct component.

Can I return or exchange the part if it doesn't fit?

Yes, of course.

If the ordered part doesn’t fit, you can return or exchange it within 30 days of the purchase date.

For the return to be accepted, the part must:

be unused and undamaged,
show no signs of installation,
be sent back in its original or appropriately secured packaging.

We care about your shopping experience, so the return process is quick and hassle-free. If you have any doubts, contact us – we’ll be happy to help you choose the right part or guide you through the return process.
