How has the new IE4 classification changed the motor market?

The IE2 regulations effectively cleaned up the lower efficiency end of the market; if an application requires a motor to operate rarely, then its energy consumption is not so critical. Users just want the cheapest machine they can buy that will be reliable in that application; the IE2 regs are intended to make sure that new motors being supplied into these conditions meet a minimum standard of efficiency.

Advanced grease lubrication enhances paper mill performance

With paper machinery often operating at speeds more than 2000m/min and steam temperatures exceeding 200degC (392degF), the equipment used in pulp and paper mills is continually placed under extreme pressure to perform. As a result, it is important for companies to select advanced lubricants, including greases, which can operate effectively in this environment.

Selecting bearings for industrial gearboxes

The requirement to improve the efficiency and performance of mechanical gearboxes has led to more powerful designs which, in turn, require bearings designed to deliver long service life. Understanding the role and design criteria for the different types of bearing within a gearbox is the key to ensuring the correct specification is used when constructing or repairing a gearbox, whatever the size. NSK is now using advanced materials and live predictive models to find the optimum product.
