Rotary Shaft Seals

               Standard Heavy Duty Seals
  

OSM-1
OSM-2
These types of profiles are mostly used in hot rolled or cold rolled steel rolling mills for sealing expensive bearing in the work rolls, intermediate rolls and backup roll chocks. Extremely longlife is assured compared to other seals. Due to a robust design providing a steel spacer and a hard CRC outer cap, this seal provides excellent retention in the housing thus increasing seal resistance to rotate or distort with the shaft as seen with conventional seals.
Speed : - The Shaft speed permissible for this profile is upto 10 m/s
Pressure : - Max. upto 0.5 bar
OSM-1 is supply with a metal spacer and OSM-2 with a rubber spacer.
