Hydraulic oil seal: key component of hydraulic system sealing
Hydraulic oil seal is an indispensable and important component in hydraulic equipment. It is mainly used to prevent hydraulic oil leakage and block external impurities from entering the system, thereby ensuring the efficient operation and service life of the equipment. Hydraulic oil seals have a wide range of applications, covering engineering machinery, agricultural equipment, industrial automation equipment, injection molding machines, hydraulic cylinders, etc.
The structural types of hydraulic oil seals mainly include:
UN type: standard U-shaped seal ring, suitable for high-pressure working environment, with stable sealing performance.
KDAS type: combined seal, integrating guidance, sealing and dustproof, suitable for reciprocating hydraulic cylinders.
DHS type: double lip seal ring, wear-resistant and pressure-resistant, suitable for high-frequency motion occasions.
ODU/IDU type: outer diameter/inner diameter seal ring, used for different installation methods, with good self-tightening sealing ability.
BS type: dustproof seal ring, effectively blocks external dust and impurities, and extends the life of the oil seal.
USI type: one-way seal for piston rod, with excellent wear resistance and self-lubricating properties.
USH type: suitable for reciprocating motion of hydraulic cylinders, especially suitable for harsh working environments.
JA type: cloth-reinforced rubber seal ring, strong pressure resistance, suitable for heavy equipment.
LBI type: has good high temperature resistance, suitable for high temperature hydraulic medium system.
GR type: guide ring, prevents direct metal contact, improves the stability of the overall sealing system.
