  • Complete strip-down and cleaning
  • Rod and barrel inspection
  • Rod repair and re-chroming coordination
  • Seal and bearing replacement
  • Honing and precision machining
  • Thread and end-fitting repairs
  • Corrosion repair
  • Component replacement
  • Pressure and function testing
  • Reassembly and final inspection

Retrofit & Upgrades

Modernise Existing Equipment
Where an existing cylinder is no longer performing as required, a complete replacement is not always necessary. Our engineers can assess the existing design and identify opportunities to retrofit, modify or upgrade the cylinder to suit new operating requirements.

01

Performance Upgrades

Improving cylinder performance, operating pressure or reliability.

02

Dimensional Modifications

Modifying mounting arrangements, ports, threads, rods or other components.

03

Seal Upgrades

Replacing obsolete or unsuitable sealing systems with modern alternatives.

04

Material Improvements

Selecting improved materials or surface treatments for demanding environments.

05

Design Modifications

Engineering modifications to accommodate changes in machinery or operating conditions.

Retrofit Seal Upgrades

Improve Reliability. Reduce Leakage. Extend Service Life.
Older hydraulic and pneumatic cylinders are often fitted with sealing systems that are no longer ideally suited to modern operating pressures, temperatures, fluids or working environments. As part of our overhaul and retrofit service, Raycom Engineering can assess existing sealing arrangements and recommend modern seal technology designed around the actual operating conditions of the equipment.
  • Replacement of obsolete or discontinued seals
  • Upgrading to modern high-performance sealing systems
  • Rod seal and wiper upgrades
  • Piston and wear-ring upgrades
  • Static and dynamic seal replacement
  • Seal material upgrades for temperature and chemical resistance
  • Improved sealing arrangements for higher operating pressures
  • Conversion of older seal profiles to modern equivalents
  • Custom seal sourcing for difficult or obsolete applications
  • Inspection of seal grooves and mating surfaces
  • Recommendations to address recurring leakage or premature seal failure

Upgrade the Seal - Not the Whole Cylinder

Where the cylinder body and major components remain serviceable, a seal retrofit can provide a cost-effective alternative to complete cylinder replacement. Our engineers can assess the existing cylinder, identify the cause of seal failure and recommend an upgraded sealing solution designed to improve reliability, service life and performance.
