Heavy Duty Seal: Expert FAQ – Terminology & Standards

1. Q: What materials are commonly used for heavy duty seal manufacturing?
   A: Nitrile rubber (NBR), fluorocarbon (FKM), EPDM, silicone for rubber seals; polyamide and polycarbonate for plastic seals. Metal casing and springs are typically made from stainless or carbon steel.
2. Q: What are the standard sizes and tolerances for heavy seal products?
   A: Sizes adhere to international standards—e.g., DIN 3760/3761, ISO 6194—covering shaft diameters from 10mm to 500mm, typical OD tolerances within ±0.15mm.
3. Q: How does the SCOT1 design of 43800 Oil Seal improve performance?
   A: SCOT1 incorporates a spring-assisted lip for stable radial pressure, improving oil retention and dirt exclusion under high-speed and high-temperature operation.
4. Q: What installation practices ensure optimal heavy duty rubber seal performance?
   A: Always use clean, lubricated shaft surfaces of correct hardness/roughness (Ra 0.2-0.8 μm), use appropriate tools, and avoid excessive distortion.
5. Q: What max temperature and pressure can heavy duty seal withstand?
   A: Premium NBR-based seals (like 43800 Oil Seal) withstand up to 100°C continuous, 1.4 MPa operating pressure.
6. Q: How are heavy duty plastic seals used in cargo and transportation?
   A: As security tags or tamper-evident locks, providing cost-effective anti-theft protection meeting ISO 17712 standards.
7. Q: How to select between single-lip and double-lip heavy duty seal?
   A: Single-lip for general oil/lubricant retention; double-lip adds dust exclusion, suitable for highly contaminated environments.
