Countermeasure: Change the seal material to one excellent in oil resistance, heat resistance, and weather resistance.
2. State: Swelling
Cause: 1. lncompatible with the oil used
2. Mixing of a foreign liquid such as cleaning solution
Countermeasure: Change seal material
3. State: Wear (mirror surface, striation, biased abrasion)
Cause:1. Excessive minimum pressure on the sliding surface
2. Long continuous pressure appliion time
3. Extremely short strokes
4. Excessive eccentricity (inappropriate bearing)
5. lnappropriate roughness of the contacting surface
