Seal Ring
What is the purpose of a seal ring?
Bearing seals primarily serve to isolate the bearing from dust, water mist, and other substances that can affect its stable operation, preventing internal wear, rust, and premature failure. They also retain lubricant, ensuring continuous lubrication, reducing maintenance, and extending bearing life. Bearing seals are mainly divided into contact seals and non-contact seals. Contact seals offer better sealing performance and are suitable for equipment operating at low to medium speeds; non-contact seals are suitable for equipment operating at high speeds.LTZC provides customized bearing sealing services.

Highly Reliable Sealing Performance
LTZC seals are made of wear-resistant rubber, fluororubber (FKM), or polyurethane, offering excellent oil, water, and dust resistance, extending sealing life by 30%–50% compared to ordinary seals.
High Precision Machining Matching
Leveraging LTZC's complete production chain, seals are designed and machined synchronously with bearings, gear rings, and slew drive structures, ensuring a sealing surface clearance consistency of ≤0.05mm, effectively improving overall sealing reliability.
Adaptable to Extreme Conditions
Maintaining stable elasticity and sealing force within a temperature range of -40°C to +180°C, suitable for wind power, marine equipment, construction machinery, and heavy-duty industrial applications.
Lower Friction, Reduced Energy Consumption
LTZC optmizes the sealing structure for slew bearings and slewing drive systems, offering various seal designs to reduce frictional resistance by 10%–15%, helping equipment improve efficiency and reduce heat generation.
Customizable Structures
LTZC offers various sealing structures including V-type, U-type, labyrinth type, and combined types. Materials, hardness, lip structure, and assembly methods can be customized to meet customer equipment requirements.
LTZC Sealing Ring Quality Assurance
LTZC sealing products and complete system kits meet ISO 9001, ISO 14001, and ISO 45001 standards and satisfy marine-grade application requirements such as CCS, BV, and ABS.
