421 Series: V-Ring – HD
The 421 Series Rotary Seal is designed to protect the internal bearing and primary seals from water splash and heavy concentrations of debris.
421 Series
The 421 Series Rotary Seal is a robust rotary internal bearing and primary seals from water splash and heavy concentrations of debris. This is commonly used on work rolls and roll neck bearings in steel and aluminum mills. The design of the seal lip is much more robust than traditional rotary face seals providing maximum performance in harsh conditions.
