Bushings

A bushing is the load-bearing element of a gland. It carries radial load and keeps the rod and bore from contacting the housing. Below are 324 Hansa Flex BK series sizes — press-in bushings in bronze and composite materials.

How to select the size

Matched by housing diameter and width. A press fit is required — otherwise the bushing will spin.

After pressing, the inner diameter shrinks. If it is critical, ream the bushing to size after installation.

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:

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

Frequently asked questions

Press fit or heat fit?
Usually a press fit with a driver. Larger bushings can be fitted by heating the housing to 80–100 °C, but no higher — the material will suffer.

Why did the bushing spin?
Insufficient interference or a damaged seat. Operating above the temperature limit is the other cause.

Should it be lubricated during assembly?
Yes, with a thin film of the working grease. Dry pressing often scores the seat.

Cylinder bushings and sleeves: rod bushings, piston bushings, bronze and composite sleeves. Genuine parts matched by inner diameter, outer diameter and length. Send the dimensions or the original part number and we confirm the exact bushing 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 bushings do you supply?

Cylinder rod bushings, piston bushings and bronze or composite sleeves.

How do I size a bushing?

Match the inner diameter, outer diameter and length, or send the original part number.

Are bushings genuine?

Yes, genuine parts.
