Special Features
Designed for two types
of bearing inserts
-
Type T , double row spherical roller bearings for heavy radial and axial loads
-
Type E , single row spherical roller bearings with lifetime internal greasing.
Please note that we do not use stainless steel bearing inserts. In our bearing assembly solutions. Even though stainless steel makes a great material for the bearing housing of the Extreme Bearing. Stainless steel makes a poor material for a bearing insert. Stainless steel inserts are often subject to fretting damage. And wear out fast. Instead, we recommend inserts made of chrome steel. Such as 100Cr6.
Type T – Self-aligning double row spherical roller bearings
- Very high radial and axial load-carrying capacity.
- Self-aligning , allow misalignment.
- Easily fitted for loads in all directions.
- Perfect concentric fit on shaft by an adapter sleeve.
E-Type Self-aligning single row spherical roller bearings
-
High radial load capacity.
- Self-aligning , allow misalignment.
-
Extra barrier to prevent contamination.
-
Sealed and greased for life.
-
Perfect concentric fit on shaft by an adapter sleeve.
Type E bearing provide a triple barrier bearing labyrinth seal prevent contamination from entering the bearing unit.
Type E bearing seals are designed to provide an extra barrier to prevent contamination from entering the bearing. In fact, an Extreme Bearing unit with a Type E insert offers superior triple protection from harsh environments and extreme conditions.As standard, Type E bearings feature 2-RS bearing seals which differentiate this type from the unsealed Type T double row spherical roller bearings. These Type E bearing seals and the lubricant are integrated into one system, so that the bearing can be kept sealed and greased for its lifetime without the need to refill. The grease nipple on the bearing housing is intended to fill the rest of the Extreme Bearing housing with grease and so prevent water and contaminants from entering.
Triple protection to shield the bearing:
- Bearing housing seals
- Grease-filled housing
- Bearing insert seals
Firstly, the housing seal made of rubber attached to the shaft provides a primary barrier. It repels dirt and contaminants using the centrifugal force generated by the shaft. Secondly, the bearing housing is filled with grease to prevent contaminants from entering and damaging the bearing. Finally, there is a type of bearing seal called 2-RS to protect the bearing.
