In the construction industry, machine reliability is the key to success. That's why we offer high-quality replacement parts for construction machinery that meet the highest standards of durability and performance. Our products are the ideal solution for companies and specialists looking for reliable components at attractive prices.

Application in machines

Brand (Machine Type) Example Ram Application
JCB (Backhoe Loaders) Bucket ram, Extradig ram on 3CX, 4CX
JCB (Telehandlers) Lift and tilt rams
JCB (Skid Steer Loaders) ROBOT

The list above is for reference. Before purchasing, we recommend verifying the dimensions (rod and cylinder diameter) on your machine.

⚠️ Safety Warning

Before replacing seals, you must completely depressurize the hydraulic system by lowering all attachments to the ground and operating all levers with the engine off. High-pressure hydraulic oil can cause serious injury. Use safety glasses and gloves.

Service Recommendation: Ensure Maximum Lifespan

To ensure a long service life for the seals, always use high-quality HYPTRON hydraulic oil and regularly change filters to proven REDX brand replacements. Contaminated oil is the main cause of damage to seals and scoring of the cylinder bore.

Part's Role in the Machine and Failure Diagnostics

Seals in a hydraulic ram are responsible for maintaining oil pressure, which translates into the force and precision of the arm's movements. Their wear leads to internal or external leaks, resulting in a loss of machine performance.

  • › Visible oil leaks from the ram gland.
  • › "Drifting down" of the arm under its own weight or under load.
  • › Lack of power on a specific function, "internal leakage" in the ram.
  • › Slow operation of the ram.

Peace of Mind Guarantee: Why Choose Our Offer?

A hydraulic leak is a waste of money and an environmental risk.

The cost of a seal kit is negligible compared to the cost of the expensive hydraulic oil that leaks out every day. Don't wait for a major failure – order a proven NEXGEN kit and restore 100% efficiency and sealing to your hydraulic ram.

🔧 Expert's Guide: Key Installation Tips

  1. Check the cylinder bore and piston rod: Before installing new seals, carefully check for any scratches, pitting, or chrome damage on the working surfaces.
  2. Maintain cleanliness: Work in a clean environment. Even the smallest contaminant can damage new seals.
  3. Use installation tools: To install the seals, especially those on the piston, use dedicated tools to avoid damaging them.
  4. Lubricate generously: All seals and rings should be generously lubricated with clean hydraulic oil before assembly.

Frequently Asked Questions (FAQ)

1. A ram is "drifting down". Will replacing the seals help?

Yes, in most cases this is the main cause. A "drifting" ram indicates an internal leak past the piston seals. Replacing the complete kit should solve the problem, provided the cylinder bore is not scratched.

2. How do I correctly measure a hydraulic ram to choose a seal kit?

You need to accurately measure two values: the diameter of the piston rod (the extending, chromed part) and the internal diameter of the cylinder (the tube in which the piston operates). In this case, it is 50 mm by 110 mm.

3. What do the different colors of the seals in the kit mean?

Different colors usually indicate different materials from which the seals are made, suited to a specific function. For example, blue or green seals are often made of polyurethane (resistant to high pressure), black from NBR rubber (flexible), and white or cream from low-friction PTFE (Teflon).
