The performance of O-ring excessive friction:
① the compression is too large;
② O-shaped rubber sealing ring overflow or poor oil resistance, excessive swelling;
The solution of O-ring excessive friction:
(1) reduce the amount of compression or correct the groove size to improve the finish of the metal surface
② The retaining ring is used to prevent the overflow of the O-shaped rubber sealing ring or to improve the oil resistance of the O-shaped rubber sealing ring material.
