- Rod Seals These ensure that no hydraulic fluid escapes through the rod exit. Properly functioning rod seals are vital for the cylinder's efficiency.

- Backup Rings These are used alongside seals to prevent extrusion under high pressure, ensuring the durability of the hydraulic cylinder's seals.

3. Pressure Maintenance Hydraulic systems rely on maintaining a specific pressure to function effectively. Oil seals help retain this pressure by providing a secure barrier that prevents fluid escape, which is crucial for optimal motor performance.

The design of wiper seals is equally important, as it impacts their functionality. There are various designs, including single-lip, double-lip, and integrated scraper seals, each serving specific applications. Single-lip wipers are simple and effective for light-duty applications, while double-lip designs provide enhanced sealing capabilities, making them suitable for more demanding environments.

2. Back-up Rings These are used in conjunction with seals to provide additional support and prevent extrusion of the seals under high pressure. Back-up rings help extend the life of the seals by preventing wear and tear.
