The JLG 7023559 hydraulic cylinder seal kit is engineered for metric hydraulic cylinder applications with a 35.00 mm rod diameter and 60.00 mm bore diameter. This precision-matched seal kit restores optimal hydraulic sealing performance, preventing fluid leakage and maintaining correct internal pressure levels in demanding industrial environments.
Hydraulic cylinders rely on properly functioning seals to maintain pressure, prevent contamination, and ensure controlled movement. Over time, exposure to pressure cycling, temperature fluctuations, and environmental contaminants can cause seals to wear or degrade. Replacing worn seals with the correct specification kit is essential to maintaining equipment reliability and minimizing downtime.
This seal kit is designed specifically for metric cylinder systems and includes sealing components matched to:
- Rod Diameter: 35.00 mm
- Bore Diameter: 60.00 mm
- Measurement System: Metric
Typical applications include:
- Lift cylinders
- Boom cylinders
- Steering cylinders
- Stabilizer cylinders
- Compact aerial work platforms
By restoring proper sealing surfaces, this kit helps:
- Prevent hydraulic oil leaks
- Maintain pressure stability
- Improve motion control accuracy
- Extend cylinder service life
- Reduce costly equipment downtime
The precision sizing ensures proper compression and dynamic sealing between the piston, rod, and cylinder barrel. Installing the correct rod and bore matched seal kit is critical to avoiding premature wear or internal bypass.
Before ordering, always confirm rod and bore measurements or verify using your equipment’s parts manual and serial number.
