Understanding Excavator Cylinder Seal Kits Function, Importance, and Selection
2. Reduced Performance If a hydraulic cylinder is not extending or retracting smoothly, or if it hesitates during operation, this might indicate seal failure or damage.
4. O-Rings Though often used in static applications, specifically designed O-rings can serve as effective shaft seals in hydraulic systems. Their circular shape allows them to compress and create a tight seal under pressure.
1. Disassemble the Cylinder Begin by carefully removing the cylinder from the hoist. Take note of all components' positions and orientations for reassembly.
A hydraulic cylinder rebuild kit typically includes several key components that are necessary for a successful rebuild
1. Regular Inspections Conduct routine inspections of hydraulic motors and their seals. Look for signs of wear, such as cracks, tears, or deformation in the seal material.
The typical construction of a skeleton oil seal includes an outer casing that fits snugly into the housing, a sealing lip that makes contact with the rotating shaft, and a metallic reinforcement that provides rigidity. This combination of materials ensures that the seal is capable of handling the dynamic conditions of machinery while maintaining an effective barrier against the ingress of dirt and the egress of lubricants.
