The latest bearing solution for arduous and demanding industries has been launched by Bearings International (BI). The new Rexnord RN series of metric bearings offers cutting edge design with unmatched ease-of-use, performance and durability. As a drop-in replacement for existing SN500 bearings, major benefits are efficiency and productivity, reduced downtime and a lower total cost of ownership.
The RN series has an industry-leading misalignment capability of a full 5 cm, a two-piece outer race and higher radial and axial load capability due to a larger roller design and seals for improved bearing life, ease of fitment and removal from the shaft thanks to a Shurlok adapter mounting. Another major benefit is no shaft damage from seal wear or the grub screw locking onto the shaft.
BI product manager, Lingesh Naidoo, explains that the new RN series comes with access to backup from BI’s technical department in conjunction with Rexnord South Africa. “The new RN series takes the guesswork out of mounting and dismounting spherical roller bearings. Unlike the conventional plumber block assembly with multiple components, the RN series unitised plumber block unit has no loose components. This reduces installation time by up to 80%,” he adds.
Industries include cement, fertiliser, power generation, steel, aggregates, mining and mineral processing. Applications range from elevators to screw conveyors, feeder breakers, roll crushers, conveyor pulleys and fans. “The RN series covers any scenario where a high load is combined with high contamination,” concludes Naidoo.
