Why does a hydraulic cylinder leak down?
When internal leaks occur, the hydraulic fluid physically moves from one side of the piston to the other, creating an uneven distribution that causes the cylinder to move or “drift.” Leaks generally occur when the piston seals, holding valve, or rod seals wear out or are compromised due to various reasons.

How are hydraulic cylinders sealed?
Hydraulic cylinders use static seals in numerous locations, depending on the cylinder’s design and construction. The most common are static seals between the piston and piston rod and between the head and cylinder bore tube.
Where is the seal kit on a hydraulic cylinder?
How to Find the Seal Kit Part Number. Check the original equipment manufacturer’s website or Google it. Contact an OEM representative or local equipment dealer for more information. Reach out to your local hydraulic repair shop to help you identify the seals.

How are hydraulic seals measured?
Measure the seal’s Outer Diameter (OD), Inner Diameter (ID), width and height. Often the dimensions are printed on the seal. If not, you can measure the seal using either a ruler, verniers or calipers. Take multiple measurements around the seal when measuring diameters, in order to apply an average measurement.

Can welded hydraulic cylinders be repaired?
Welded cylinders come in welded designs hence difficult to repair, but rod seals and assembly of piston rods can easily be removed for service. On the other hand, tie-rod cylinders are easily repaired or, if necessary, repacked.
How do you rebuild a log splitter cylinder?
How many seals are in a hydraulic cylinder?
To contain the pressurized fluids in a hydraulic cylinder system and keep it in motion, a complex configuration of high-performance seals in two basic categories are required: (1) static seals and (2) dynamic seals (supported by guide rings).
What are two types of hydraulic seals?
Hydraulic Seals types
- Piston Seals.
- Rod Seals.
- Wiper Seals.
- Wear Rings.
What type of seal ring is usually used to seal a piston in a hydraulic cylinder?
The piston rod sealing ring is made of polyurethane or nitrile rubber. In some cases, it needs to be used with a supporting ring (also called a retaining ring). The support ring is used to prevent the seal ring from being deformed under pressure. There are also many variations of piston rod seals.
How do I know what kind of hydraulic cylinder I have?
The model code is shown on a plate attached to the head or cap of the hydraulic cylinder. If the plate is damaged or missing, the cylinder can be identified from its stamped serial number, usually found on the head.

What is a PTFE seal?
Radial shaft seals with one or more PTFE sealing lip(s) are designed to withstand aggressive environments, high temperatures, high pressures and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand. Many of the PTFE compounds are FDA approved.
How are shaft seals installed?

Which way does the spring go on a oil seal?
Which way does a double lip seal go?
Orient your seal the same way as the initial install. The sealing lip should face the lubricant that requires sealing. The second lip on a double lip oil seal is intended as a dust lip. The seal must be installed at a 90°, or perpendicularly, to both the shaft and housing bore.
Which way do you put on a lip seal?
The lip seal is properly installed when it is in the correct position with the seal lip opening facing the appropriate direction. This will allow grease to pass through the seal during greasing, but will prevent dirt, grit, and water from entering the bushing area. seals have been installed backwards.
Should oil seals be installed dry?
For the oil seal to operate correctly, the seal lip must be aligned with the medium to be sealed. To make it easier to slide over the shaft, both the shaft and the oil seal lip must be lubricated properly beforehand with grease or oil. Oil seals with a leather seal lip must be soaked in oil for some time in advance.
