Professional FAQ: About 55×72×7 Tcv Oil Seal High Pressure Oil Seal

Q1: What does TCV mean in oil seal models?

TCV refers to a double-lip oil seal with a dustproof outer lip and reinforced inner metal case, designed for high pressure and contaminated environments. It provides improved sealing efficiency and extended service life.

Q2: What are the main materials for 55×72×7 Tcv Oil Seal High Pressure Oil Seal?

The main options include NBR (Nitrile Butadiene Rubber) for standard oil resistance, FKM (Viton®) for high temperature/chemical resistance, and PTFE for extreme temperature and friction conditions.

Q3: What is the maximum working pressure?

55×72×7 Tcv Oil Seal High Pressure Oil Seal can withstand pressures up to 1.2 MPa (12 bar), outclassing general purpose oil seals (see chart above).

Q4: Can it be used in high-speed shafts?

Yes. The design supports rotational speeds up to 20 m/s with proper lubrication — suitable for pumps, gearboxes, or vertical shafts.

Q5: What international standards are met?

Compliant with ISO 6194 and ASTM D2000 for oil seal dimensions, performance, and elastomer specification.

Q6: Is special installation equipment needed?

Installation can usually be achieved with standard press-fit tools. However, correct seating and shaft/bore roundness are essential (installation guides).

Q7: What about shelf life and storage?

Seals should be stored away from direct sunlight, ozone, and with stable temperature/humidity. Depending on the material, shelf life can reach 5-10 years.
