O-ring excessive friction performance and solution

O-ring excessive friction performance: ① compression is too large;

(2) O-shaped rubber sealing ring overflow or poor oil resistance, excessive swelling;

The solution to excessive friction of O-ring: ① Reduce the amount of compression or correct the groove size to improve the finish of the metal surface

② Use a stop ring to prevent the overflow of the O-shaped rubber seal or improve the oil resistance of the O-shaped rubber seal material.
