Common Questions & Answers:
Q1: What is the function of a double lip in this rotary shaft oil seal?
A1: The double lip design provides two sealing surfaces—one to retain lubrication and another to exclude external contaminants, improving overall sealing performance and extending equipment life.
Q2: Why is nitrile rubber (NBR) used for the lip material?
A2: NBR is known for its excellent resistance to petroleum-based oils, fuels, and other chemicals, as well as its flexibility and wear resistance, making it ideal for dynamic sealing applications.

FAQs about Shaft Oil Seal TC34x53x8 Rubber Covered Double Lip w/Garter Spring ID 34mm OD 53mm 34x53x8 34 x 53 x 8 mm Oil Seals
Q1. What does TC mean?
A1. TC indicates a double-lip design with a spring for better sealing.
Q2. What do 34.0×53.0×8.0 mean?
A2. Inner diameter, outer diameter, and width in millimeters.
Q3. How do I measure oil seal size?
A3. Measure the shaft (ID), the bore (OD), and the housing groove width (W) with calipers; match to the printed size.
Q4. How do I install a TC oil seal?
A4. Lightly oil the lips and shaft; protect threads/keys; press the seal squarely using a driver; primary lip faces the fluid.
Q5. Which way should the lips face?
A5. The primary lip faces the fluid; the dust lip faces outward to block contaminants.
Q6. What shaft surface finish and hardness are recommended?
A6. Typical Ra 0.2–0.8 µm with proper hardness and no burrs or spiral grooves; confirm per your standard.
Q7. When should I choose NBR vs FKM?
A7. NBR suits oils up to ~100 °C; FKM handles higher heat and aggressive media.
Q8. Is FKM the same as Viton?
A8. Viton® is a brand of FKM fluoroelastomer; use FKM as the generic name.
Q9. Can this seal handle pressure?
A9. Standard TC is for low pressure (up to ~0.03 bar). Use pressure-rated designs above spec.
Q10. Common causes of early failure?
A10. Misalignment, dry-running, wrong material, poor shaft finish, contamination, or over-speed/temperature.
Q11. Do I need lubrication during installation?
A11. Yes, lightly oil the lips and shaft to reduce start-up wear and friction.
Q12. Typical storage guidance?
A12. Store cool, clean, and dark; avoid ozone/UV; use within recommended elastomer shelf life.
