Our ZZHT330 range of high-temperature bearings has the highest temperature capacity of all our bearings. With the addition on metal shields, it has been engineered specifically for high-temperature applications where environmental contamination is present.
The unique combination of increased radial clearance, surface coatings, and high-temperature grease designed for applications up to 330°C makes this bearing perfect for use in glass manufacturing, steel and iron production, and brick manufacturing kiln carts.
Although this range is supplies shielded, we still recommend frequent maintenance (re-lubrication) with respect to the severity of the application.
