Sealing Technologies

The addition of Inpro/Seal® in January 2010 makes Waukesha Bearings® the premier provider of custom engineered bearings and permanent bearing protection.

Inpro/Seal is the leading designer and manufacturer of engineered system and bearing protection products for rotating equipment in a variety of industries. Since inventing the original Bearing Isolator in 1977, Inpro/Seal has been delivering innovative bearing sealing solutions and superior customer service to customers around the globe. Inpro/Seal technologies increase the reliability of rotating equipment and provide real cost savings by improving the mean time between repair (MTBR). Same day shipments are available on most products – even new designs.

  • Bearing Isolator – non-wearing, non-contacting, permanent bearing protection to prevent against lubrication loss and contamination ingress.
  • Air Mizer® – non-contacting shaft seal to prevent against product loss, harmful emissions and contamination
  • Current Diverter Ring® (CDR®) / Motor Grounding Seal™ (MGS®) – complete shaft grounding to protect bearings against stray electrical currents
  • Sentinel® Floating Brush Seal – a seal to extend maintenance intervals and stop costly steam leakage on process steam turbines
