The ZZHT270 series of bearings is perfect for applications were cleanliness is obligatory and regular maintenance and re-lubrication is not a possibility. This is down to its high-temperature capabilities, load ratings, relatively high speeds, and the metal shields giving added protection.
With a specialist combination of surface coatings and increased radial clearance, this bearing series has been developed specifically to handle these high-temperature applications whist shielding against contamination. It is regularly used in ceramic industry kilns, brick kiln carts, glass production, and the steel and iron industry.
