BI launches new Rexnord RN series for demanding applications

The latest bearing solution for the toughest and most demanding industries comes from leading supplier Bearings International. The new Rexnord RN metric bearing series offers state-of-the-art design with unmatched ease of use, performance and durability.

As a direct replacement for existing SN500 bearings, the main customer benefits are efficiency and productivity, reduced downtime and lower total cost of ownership.

The RN series has an industry-leading 2° misalignment capability, a two-piece outer ring, and higher radial and axial load carrying capacity through larger roller design and seals for improved bearing life, ease of assembly and removal from the shaft. thanks to a SHURLOK adapter mount. Another major advantage is the absence of damage to the shaft due to seal wear or the grub screw locking onto the shaft.

The new RN series is available across BI’s extensive branch network, with access to BI Technical Service support in conjunction with Rexnord South Africa, says Lingesh Naidoo, BI Product Manager, who has day 23 years of experience with the Rexnord range. Although the Rexnord range has been represented locally for over 40 years, this is a first for South Africa in terms of the range of ISO metric sized unitized plumber’s bearings available.

“The new RN series simplifies the mounting and dismounting of spherical roller bearings where it’s needed most. Unlike the conventional plumbing block assembly with multiple components, the RN series unified plumbing block unit has no loose components. This, combined with other technological features, reduces installation time by up to 80%,” Naidoo points out.

Industries include cement, fertilizers, power generation, steel, aggregates, mining and mineral processing. Applications range from elevators to screw conveyors, feed crushers, roller crushers, conveyor pulleys and fans.

“The opportunities for the RN series are very broad, as they cover all scenarios where high load is combined with high contamination,” says Naidoo. As the world leader in bearing solutions, the new RN series is based on Rexnord’s 150 years of industry experience and state-of-the-art design. The series will be completed with 24/7 technical support and after-sales service, in addition to theoretical and practical training as well as installation and installation supervision.
