3. Aerospace High-pressure oil seals are essential in aerospace applications, where they are used in engines and landing gear, where they withstand not only high pressures but also extreme temperatures and environmental conditions.

Replacing a rear hub seal is a job best left to a professional mechanic, as it involves dismantling and reassembling the rear axle. The mechanic will first need to drain the lubricating oil from the axle housing before removing the rear wheels and brake components. Once the axle is exposed, the mechanic can then remove the old rear hub seal and replace it with a new one. After reassembling the axle, the mechanic will refill the axle housing with fresh lubricating oil and check for any leaks.

- Manufacturing Machinery used in factories, particularly those dealing with raw materials like wood, metal, or plastic, often incorporates dust proof seals to enhance durability.

The primary function of oil seals is to retain lubricant within a mechanical assembly. In the absence of an effective seal, lubricants can escape from the machinery, leading to increased wear and tear on moving parts, reduced efficiency, and potential failures. In industries where machinery operates under high temperatures and pressures, such as automotive, aerospace, and manufacturing, the significance of oil seals is magnified.

2. Decreased Performance If the hydraulic ram is struggling to lift or move loads effectively, it may be due to seal wear leading to loss of hydraulic pressure.

1. Compatibility Ensure the seal kit matches the specific hydraulic cylinder model in terms of dimensions and materials.
