NSK Bearings for Steel & Non-Ferrous Industries
The operational environment for bearings is unique to steelmaking, comprising particle contamination, water and heat.
In addition, the bearings may have to cope with heavy or shock loads and vibration, operational speeds ranging from extremely slow to extremely high, coupled with rapid acceleration and deceleration.
We offer a comprehensive range of bearings for the steel industry, from standard bearings to our own independently developed, high-capacity specialised bearings.
A typical problem for bearings in converters: the swivel bearing cannot be replaced without dismantling the central wheel.
NSK's ultra-large split Spherical Roller Bearings allow bearing replacement without removing the central wheel of the gearbox, thus reducing maintenance cost and shortening downtimes.
Ultra-large split bearings for BOF's & Converters making maintenance & bearing changes less time consuming. >>
Differential speeds in the roller/raceway contact zone can cause uneven wear in spherical roller bearings and toroidal roller bearings. Spalling and cracks on the raceway of the outer ring are costly as they cause unplanned production stoppages and above-average consumption of bearings.
To tackle this problem, NSK has developed a range of full complement cylindrical roller bearings effective as non-locating position in guide rolls of continuous casting machines.
In order to meet the requirements of steel making equipment and continuous-casting machines, NSK has expanded its range of cylindrical roller bearings. NSK has developed the new NUB series which can reduce the total cost of ownership for continuous casting machine guide rolls >>
This type of spherical roller bearings provide solutions to challenges in continuous casting guide rolls. >>
NSK offers specific bearings for rolling mills which guarantee higher reliability and longer operational service lives.
Sealed bearings minimise the environmental impact and help reduce grease consumption.
Super-Tough steel (STF series) with optimum heat treatment prevents cracks and early raceway damage.
In addition, NSK has developed WTF material (WTF series) for bearings which are exposed to water infiltration.
The four-row extra-capacity sealed-clean taper roller bearings (KVS series) are capacity-optimised, resistant to contamination by foreign matter and now also available with specially formulated grease against water infiltration.
These bearing are designed to prevent cracking of rollers generated by extremely heavy rolling loads. >>
