Integrated bearing assemblies for tough applications

Third Quarter 2022 Shaft power components

BMG’s comprehensive range of NSK bearings extends from precision miniature bearings used in machine tools and electronics applications to giant-sized bearings for steel and mining industries. Included in the NSK portfolio are integrated bearing assemblies designed especially for vibratory screen machines, which are used in arduous construction, agriculture, quarrying and mining applications. “We have found that vibrating screen machine manufacturers often experience difficulties resulting from the inconsistency of bearing mountings in the shaker box assembly,” says business unit manager, Carlo Beukes. “Our solutions encompass integrated bearing assemblies with high strength SG iron housings, and vibratory-specification bearings. Important advantages of these customised assemblies are that manufacturers do not need to rework the designs of the system in-house and the integrated assembly also means customers do not need to manufacture sub-components. Each bearing assembly unit is simply bolted down to the machine frame, which has been pre-greased and fitted with labyrinth and contact seals, ready for fit with bearing location features.”

NSK’s simple bolt-on assembly solutions encompass vibratory specification bearings, which reduce vibration and noise levels by as much as 50%. This integrated system also offers increased fatigue strength against vibration and shock loads. Other features include minimal wear and corrosion resistance.

As a result, bearing performance and reliability is improved, manufacturing costs are reduced and service life of the system is significantly extended. BMG’s Bearings division has a team of qualified product specialists available to assist customers with accurate product selection and bearing failure analysis, to ensure optimum bearing life and plant availability.
