Vibratory Rollers – Bearings for Eccentric Shafts


Conventional cylindrical roller bearings are often not suitable for vibratory rollers due to the high requirements placed on the bearings. Our engineers have therefore taken development further. New series in X-life premium quality are the result. For example, FAG single-row cylindrical roller bearings NJ with solid brass cages. Here, X-life means up to 18% more load carrying capacity. As a result, the basic rating life has increased by more than 70%. Or the low-friction cylindrical roller bearings, series LSL (with disk cage) and ZSL (with plastic spacers). They represent a development that satisfies demanding requirements in terms of dynamics and load carrying capacity. In vibratory compaction equipment, for instance, where bearing speeds reach 2,500 rpm and accelerations up to 500 m/s², innovative INA bearings have been used successfully for years.
