Подшипники NSK для производства стали и цветных металлов
Условия применения подшипников при изготовлении стали весьма специфичны и подразумевают грязную среду, воду и высокую температуру. Кроме того, подшипники могут подвергаться ударным нагрузкам и вибрации, а также использоваться на рабочих скоростях, которые варьируются от экстремально низких до чрезвычайно высоких, т.е. испытывать сильное ускорение или, наоборот, снижение хода. Такие условия представляют собой уникальную среду применения, не характерную для других отраслей.?????
Мы предлагаем полный номенклатурный ряд подшипников для сталелитейной промышленности: от стандартных подшипников до специальных подшипников собственной разработки с повышенной грузоподъемностью. Компания NSK также удовлетворяет спрос на изделия с высокой добавленной стоимостью и применение экологически безопасных методов.?
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
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.
Cylindrical Roller Bearings - NUB Series
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?>>
SWR Series Roller Bearings
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.
Four-Row CRB with Stud-Type Cage
These bearing are designed to prevent cracking of rollers generated by extremely heavy rolling loads. ?>>
Taper Roller Bearings - 4 rows - Long Life
NSK solution for four-row tapered roller bearings in rolling mills. These bearings offer long service life, reduced maintenance cost and increased operational efficiency.
Optional we offer: Super TF, WTF, Sealed Clean and
new grease AQGRD?>>
Long-life sealed backup roll bearings
Specifically designed for cluster and sendzimir mills to achieve long life and high speed operating conditions. ?>>
