- When replacing, the PTFE sealing lip of the new oil seal should not be in the same position as the old oil seal. The diameter of the sealing lip should be smaller than the shaft diameter.
- The dimensions 45x62x8 denote the outer diameter, inner diameter, and thickness of the oil seal, respectively. In this case, the outer diameter measures 45mm, the inner diameter stands at 62mm, and the thickness is 8mm. These measurements are critical as they determine the compatibility of the seal with different mechanical components, ensuring a snug fit and optimal performance.
Beyond the variety of lip designs, oil seals also come in various case designs, each serving a unique role. Here are some of the most common ones:
2. Silicone – Used in specific applications where only light loads are applied.

Names and functions of seal components
When a seal is angularly misaligned – or cocked on the shaft – an irreversible process begins. Excessive pressure on one section of the seal, when not installed properly, can cause the spring to become dislodged or the seal to heat up and become brittle through excessive wear, both leading to a premature failure.
