JCB Cylinder Gland Guide Ring
Gland guide ring designed for hydraulic cylinders in JCB rough terrain forklifts. This component acts as a slide bearing, tasked with precisely guiding the piston rod within the gland and absorbing lateral loads acting on the cylinder. It prevents direct metal-to-metal contact between the piston rod and the gland, which is crucial for avoiding seizing and scoring of the cylinder's working surfaces.
Specifications and Technical Parameters:
- Component Type: Gland guide ring (wear ring).
- Material: Polymer composite with a low friction coefficient and high resistance to surface pressure.
- Function: Piston rod centering, radial force absorption, and protection of main pressure seals against uneven wear.
- Operating Environment: Hydraulic oil, variable operating temperatures.
Compatibility with JCB Forklifts:
| Rough Terrain Forklifts 930 |
930-2 [T0] (1986 - 2004), 930-4 [T0] (1985 - 2004) |
Technical Advice: The condition of the guide ring directly impacts the integrity of the entire cylinder. If the guide wears out excessively, the piston rod begins to operate "unnaturally," leading to rapid damage of the lip pressure seals and subsequent oil leaks. During replacement, the piston rod surface must be thoroughly inspected—any pitting or scratches will act like a file on the new guide. It is recommended to install the ring on a clean surface, slightly moistened with hydraulic oil.
