HIgh-temp bearings suffix HT4 are suitable for slow speeds and temperatures up to 400°C
Technical Characteristics
- AISI 52100 Steel
- Increased radial clearance (multiple of C5)
- Manganese Phosphate surface treatment
- Increased radial clearance to compensate expansions
- Enhanced lubrication with special grease high–temp paste (MoS2 + Graphite) heat resistant up to 450º, High-temp Deep Groove Ball Bearings with the suffix HT4 are filled with a high-temp paste, which hardens after reaching a certain temperature (200º), it will harden to form a highly effective lubricating powder layer that helps reduce friction, allowing parts to operate more smoothly and bringing high economic
- ZZ and OPEN available
- This technical solution avoids the use of steel cage that is normally the weak element of the bearing in the application of high temperatures. The greatest number of spheres within the bearing allows for an increase of load capacity, especially in high temperature. This product has been produced allowing exceptional performance in terms of durability in applications more demanding. In particular its application is recommended where frequent changes are presented in the direction of rotation of the bearing and with irregular loads
Fields of use
- Brick manufacturing kiln karts
- High temperature rollers
- Iron and steel industry
- Die-casting mfg
- Glass manufacturing
- Etc.
