Professional FAQ: 45*80*7 TCV Oil Seal Hydraulic Seal
Q1: What does TCV refer to in oil seal design?
A: TCV indicates a double-lip profile with a spring-loaded sealing lip and a secondary dust lip. This structure enhances both oil retention and exclusion of contaminants, crucial for hydraulic & heavy-duty environments.
Q2: Which materials are available for 45*80*7 TCV Oil Seal Hydraulic Seal?
A: Options include NBR (nitrile, for oil/hydrocarbon resistance), FKM (fluorocarbon, for high-temp/chemical), and PTFE (extreme chemical/high speed). Selection depends on fluid, temperature, and required lifespan.
Q3: What installation standards should I follow?
A: Follow ISO 6194-4 and DIN 3760: ensure correct shaft surface finish (Ra ≤ 0.4μm), handle with clean gloves, and avoid deformation of lip/spring during pressing. Lubricate both lip and shaft during assembly.
Q4: How do you validate the quality of each batch?
A: Every batch undergoes dimensional CMM inspection, hardness measurement (Shore A), accelerated aging, and dynamic rotary test under simulated service conditions (per ISO 6194). Full QA records are archived for 10 years.
Q5: What is the recommended shaft speed and pressure for 45*80*7 TCV Oil Seal Hydraulic Seal?
A: Typical operating shaft speed is up to 8 m/s and pressure rating up to 0.5 MPa, depending on the seal variant and material. For high-speed/pressure, select FKM or PTFE blends with an appropriate garter spring.
Q6: Can I order seals with custom sizes or FDA-approved compounds?
A: Absolutely. HKAiseal provides custom molding services (minimum order applies) and supplies FDA-compliant (CFR 177.2600) and WRAS-approved compounds by request.
Q7: What is the difference between TCV, TC, and TB profiles in oil seals?
A: TCV: double-lip with enhanced dust exclusion; TC: standard double-lip oil seal; TB: single-lip for low-dust or low-pressure settings. Profile choice depends on application risk and fluid characteristics.
