The latest bearing solution for the most arduous and demanding industries is being launched by leading supplier Bearings International. 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 customer 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 2°, 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.
The new RN series is available throughout the extensive BI branch network, with access to back-up from BI’s Technical Department in conjunction with Rexnord South Africa, explains BI Product Manager Lingesh Naidoo, who has 23 years’ experience with the Rexnord range to date. Although the Rexnord range has been represented locally for over 40 years, this is a first for South Africa in terms of the line of ISO metric sized unitised plumber block bearings available.
“The new RN series takes the guesswork out of mounting and dismounting spherical roller bearings, where it is needed the most. Unlike the conventional plumber block assembly with multiple components, the RN series unitised plumber block unit has no loose components. This, together with other technological features, reduces installation time by up to 80%,” highlights Naidoo.
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 opportunities for the RN series are very broad, as it covers any scenario where a high load is combined with high contamination,” explains Lingesh.
As the global leader in bearing solutions, the new RN series is based on Rexnord’s 150 years of industry experience and cutting-edge design. The series will be supplemented by technical back-up and 24/7 aftersales service, in addition to theoretical and practical training as well as installation supervision and installation.
