Guide rings

A guide ring does not seal — it centres the piston or rod and absorbs side loads. Its wear is what causes bore scoring and a leaking rod seal, even when the seal itself is intact. Below are 415 Hansa Flex sizes: EGTP, IGTP, GT, WR and WP series.

How to select the size

Matched by diameter and groove width. The material is glass-filled PTFE or bronze, depending on load and speed.

Under high side loads (forestry grapples, booms) two rings are fitted and their width is increased.

Materials

The material is chosen by medium and temperature, not by price:

  • NBR — the standard for mineral oil, −30…+100 °C. Most common and least expensive.
  • FKM (Viton) — up to +200 °C, aggressive media, brake fluid. Three to five times the price of NBR.
  • PU (polyurethane) — high pressure and abrasion, but not above +80 °C.
  • PTFE — chemicals, very low friction, but poor under compression without support.
  • EPDM — water, steam, glycol-based brake fluid. Not compatible with oil.

Common fitting mistakes

Three mistakes that make a new seal leak within a day:

  1. Damaged lip during fitting. The seal is pushed over threads or splines without a sleeve — the lip is cut and you cannot see it.
  2. Measuring a worn part. The old ring has lost its shape, so the new size does not seat in the groove.
  3. No back-up ring. Above 160 bar the seal extrudes into the gap.

Frequently asked questions

Can a guide ring replace a back-up ring?
No — the jobs are different. A guide ring centres the piston and takes side load; a back-up ring prevents O-ring extrusion.

Why does cylinder bore scoring appear?
Worn guide rings let the piston touch the wall. A bent rod is the other common cause.

PTFE versus bronze?
PTFE does not damage the bore if abrasive gets in and handles higher speeds. Bronze carries higher specific load.

Guide rings centre the piston or rod in the cylinder and absorb side loads, protecting the seal from uneven wear. We supply PTFE, bronze-filled PTFE, POM and phenolic guide rings as genuine parts with the original dimensions. Selection depends on the bore or rod diameter, the groove width and the expected side load; split rings are used where installation over a rod is required. Send the part number or the groove dimensions together with the rod or bore diameter and we confirm the correct ring within 24 hours.

Frequently Asked Questions

Do you supply genuine parts or Chinese equivalents?

Genuine parts are our main business. If you need a lower-cost option, we can also look for a Chinese-made equivalent with the same mounting dimensions and ratings.

What is the lead time?

It depends on the supplier. If the factory has stock or produces in China, we ship quickly. A factory order that must be manufactured or shipped from abroad takes longer. We confirm the exact date in your quote.

How do I place an order?

Send the part number, a photo of the nameplate, or the machine model. We confirm availability and price within 24 hours.

What are the payment and shipping terms?

EXW by default. 20-50% prepayment, balance before shipment. We can work with your freight forwarder.

What is a guide ring for?

It centres the piston or rod and absorbs side loads, protecting the seal from wear.

Which materials do you supply?

PTFE, bronze-filled PTFE, POM and phenolic resin guide rings.

Are guide rings genuine?

Yes, genuine parts with the original dimensions.

Need a price or an equivalent?

Send the part number or a photo — we will match it and reply within 24 hours.
