The heavy construction industry uses a big variety of highly specialized vehicles, such as concrete mixer trucks, that operate in the most rugged and adverse conditions, yet still require low-friction operation. For this very reason, the RKB spherical roller bearings WOR series, with wider outer ring, are expressly developed and engineered to accommodate large angular deflection between mixing drum and driving gear in case of misalignment. In addition, the RKB Group has recently enhanced its range of WOR bearings for both MRO applications and OEM programs by means of a new customized item (110x180x75/84 mm).
