The first figure, 22%, typically refers to the efficiency rate of a sealing system. In many mechanical applications, oil seals operate under various conditions and stresses. A 22% efficiency rating means that seals must be capable of withstanding fluctuations in temperature and pressure, ensuring that the lubricating oil remains contained. A higher efficiency rate often translates to a longer lifespan for machinery, thus saving costs in maintenance and potential downtime.

1. Lip Seals These seals feature a lip that contacts the shaft. The design allows them to adapt to the shaft's movement, minimizing leak paths. They are ideal for applications where space is limited.
Maintenance and Replacement
1. Contaminant Protection Dust lip seals are specifically designed to keep harmful contaminants out of critical areas within machinery. By forming a tight seal, they help to protect bearings, gears, and other internal components from abrasive particles that could lead to premature wear.

6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.
