Frequently Asked Questions
You should measure the inner diameter (shaft size), outer diameter (housing size), and the width of the seal. You can also refer to the OEM number in our catalog for an exact match.
The metal ring provides necessary structural rigidity, ensuring the seal remains seated firmly in the hub and resists deformation under high pressure.
While these are hub oil seals, we also offer specialized High Pressure Oil Seals and Hydraulic Seal Kits specifically designed for high-pressure environments.
Yes, we provide customized manufacturing services. Please provide your detailed dimensions and material requirements for a tailored quote.
For extreme temperatures, we recommend NBR+PTFE or HNBR compounds, which offer superior thermal stability compared to standard rubber.
For standard sizes in our catalog, we usually ship within 3-7 business days. Custom sizes may require a longer production window.
