CR Seal Functions
Rotating shafts need a bearing arrangement for smooth and efficient operation, and bearing arrangements need a sealing solution for protection and to achieve maximum service life. The sealing solution seals the opening between components and must perform on or more primary seal functions which include:
- Retaining the lubricant necessary for smooth operation
- Blocking the entrance of contaminants
- Separating two different media within an application
- Sealing under pressure

CR Seal Types
Radial Shaft Seals– These seals sit between rotating and stationary machine components, or between two components in relative motion.
Cassette Seals– These seals boast a design optimized to provide excellent retention of grease or oil as well as maximum protection against both liquid and solid contaminants that could otherwise upset performance.
Wear Sleeves– Optimized for radial shaft seals, this thin sleeve slides into position over the worn area to provide counterface surface.
Track Pin Seals– Track pin seals are manufactured for use in oil-lubricated track chains within off-highway applications.
Metal Face Seals– These seals make up two identical sealing rings designed to withstand the harshest operating conditions at low circumferential speeds.
V-Ring Seals– These axial shaft seals come in two types– an all rubber variety, as well as an option with metal casing known as MVR seals.
Axial Clamp Seals– Axial clamp seals are made for use with large and extra large shaft diameters, sealing axially against a rotating counterface.
