Hydraulic cylinder parts
Glands, extended glands, pistons, press-fit glands, end caps, tie rod cap nuts and lift cylinder clamp mounts: cylinder parts machined ready to size.
In cylinder manufacturing and overhaul, machined parts take the most time; a ready-made part shortens machine time and lead time. We supply the machined parts we use in our own cylinder production to companies that build and overhaul cylinders, and machine parts in non-standard sizes in our workshop. We ship cylinder parts from stock anywhere in Türkiye and abroad, and also sell them through our online store hidroticaret.com (Turkish).
Types
Cylinder gland
The front cover on the rod side of the cylinder. It guides the rod and carries the rod seal and wiper; it is the part replaced most often in overhauls.
Extended gland
The long-body version of the gland. By increasing the rod bearing length it gives more stable running against side load and bending.
Piston
The part that converts pressure into force. Force is directly proportional to piston area; the full area works in push, the area less the rod cross-section in pull.
Press-fit gland
A gland that is driven into the tube instead of being threaded. Preferred on large bores; stocked sizes are concentrated at Ø140 and above.
End cap (plain type)
The base that closes the side of the cylinder without the rod. A plain type with no oil port; the mounting is made with a separate element (clevis, rod end, flange).
End cap (with oil port)
The base cap with an oil port. Taking the line directly from the cap gives a tidier assembly than opening a port in the side wall of the tube.
Tie rod cap nut
The nut that presses the cap against the barrel on tie rod cylinders. If the tightening torque is not applied correctly, the cap leaks.
Lift cylinder clamp mount
A clamp that mounts the cylinder by gripping its barrel. Used in layouts where mounting from the cap is not possible.

How to select
Parts are selected by the two main dimensions of the cylinder: rod side parts (gland, extended gland, piston) are designated by cylinder bore × rod diameter, body side parts (end cap, nut, clamp) by cylinder inside diameter × outside diameter. The table below shows which dimension each part is designated by and its diameter range.
Because the gland carries the rod seal, the wiper and the rod guide ring, it is the part replaced most often in overhauls. In cylinders with high side load and a long stroke, an extended gland increases the bearing length and prevents the rod from bending.
When a part is replaced, the seal groove dimensions should be checked as well: the new part must match the groove dimensions of the seal profile to be used. We select the sealing elements from Kastaş profiles together with the part.
Designation dimension and diameter range of cylinder parts
| Part | How it is designated | Diameter range |
|---|---|---|
| Cylinder gland | Cylinder bore × rod diameter | Ø32-Ø250 |
| Extended gland | Cylinder bore × rod diameter | Ø50-Ø150 |
| Piston | Cylinder bore × rod diameter | Ø32-Ø250 |
| Press-fit gland | Cylinder bore × rod diameter | Ø140-Ø250 |
| End cap (plain type) | Cylinder inside diameter × outside diameter | Ø32-Ø250 |
| End cap (with oil port) | Cylinder inside diameter × outside diameter | Ø40-Ø250 |
| Tie rod cap nut | Cylinder inside diameter × outside diameter | Ø50-Ø180 |
| Lift cylinder clamp mount | Cylinder inside diameter × outside diameter | Ø63-Ø130 |
Diameter ranges are taken from the machined parts series in the catalog; non-standard sizes are machined in our workshop.
Frequently asked questions
Which dimensions do I need to order a hydraulic cylinder part?
Rod side parts by cylinder bore × rod diameter (for example 63 × 40), body side parts by cylinder inside diameter × outside diameter (for example 63 × 75).
When is an extended gland needed?
In cylinders with a long stroke and high side load; by increasing the rod bearing length it prevents the rod from bending and the seal from wearing on one side.
What is a press-fit gland?
A gland that is driven into the tube instead of being threaded; preferred on large bore cylinders.
Do you make cylinder parts in non-standard sizes?
Yes. Just send us the dimensions or the old part; we machine the part in our workshop.
Do you supply the seals together with the part?
Yes. We select Kastaş profiles that fit the seal grooves of the part, together with the part.
