Q1: What type of seal is Rvton floating seal?

A: RVTON floating seal is a mechanical face seal – also known as a floating seal, duo cone seal, toric seal, or axle seal. It consists of two high‑hardness metal rings and two elastomeric O‑rings, engineered for rotating shaft sealing applications such as axles, wheel hubs, final drives, and track rollers. 

Q2: What materials are used in the RVTON floating seal?

A: RVTON uses GCr15 bearing steel or high‑alloy cast iron (15Cr3Mo) for the metal rings, achieving a hardness of 58–68 HRC. The O‑rings are available in NBR, FKM, silicone, or HNBR to match your operating environment (temperature, chemical exposure, etc.).

Q3: How long does the RVTON floating seal last?

A: Under normal heavy‑duty operating conditions, the RVTON floating seal provides 3,000–8,000 hours of service life. This is backed by an 18‑month factory warranty.

Q4: Can the OEM seals be interchanged with RVTON seals?

A: Yes, RVTON has cross‑referenced combination numbers for the same sealing application, making them fully interchangeable.

Q5: What is the MOQ for the floating seal?

A: Our MOQ is 1 set. We maintain stock of common sizes, with a monthly capacity exceeding 50,000 sets and a typical lead time of 1–2 weeks.

Q6: How should I install the mechanical face seal?

A: Installation requires ensuring the housing and seal faces are thoroughly cleaned before assembly. Specialized installation tools are recommended to avoid damaging the precision‑lapped seal faces. The two metal rings should be installed face‑to‑face, and the O‑rings should be properly seated without twisting. For detailed guidance, contact our technical support team.

Q7: Can I get a sample before placing a bulk order?

A: Yes, we welcome sample orders with MOQ as low as 1 set. Material certification, dimension reports, and test certificates are available upon request to verify product quality before bulk order placement.
