With the highest temperature capability of the UNASIS High Temperature range and the addition of metal shields, the ZZHT330 high temperature bearing range is engineered specifically for applications that need high temperature capability and where environmental contamination is present.
With the unique combination of increased radial clearance to compensate for thermal expansion variation and surface coatings, coupled with high temperature grease designed specifically for applications up 330°C the ZZHT330 high temperature bearing range is often used in glass manufacturing, steel and iron production as well as brick manufacturing kiln carts.
Although the ZZHT330 series is supplied shielded, it is still recommended that frequent maintenance is carried out (re-lubrication) with respect to the severity of the application.
