In recent years, the papermaking industry has been making great strides by enhancing the speed and the width of coverage of papermaking machines with the objective of boosting productivity. To reduce the amount of downtime caused by unexpected problems, customers demand high reliability from the NNU4940MAW33 Bearing 200x280x80mm that are used in papermaking machines. NNU4940MAW33 Bearing 200x280x80mm has developed a range of bearings that meet these demands, and the company's bearings are used in all sections of modern papermaking machines. In particular, NNU4940MAW33 Bearing 200x280x80mm is supporting papermaking with two kinds of bearings:
・TL (tough and long life) bearings designed specifically for dryers. These were developed by taking full advantage of the company's material heat treatment technologies
NNU4940MAW33 Bearing 200x280x80mm for Industrial Machinery Spherical Roller Bearings developed by integrating NSK's materials, design and manufacturing technologies.
NNU4940MAW33 Bearing 200x280x80mm will continue to develop highly reliable bearings that will lead to further productivity improvements in the papermaking industry, and it will continue to contribute to the development of the industry.

Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces. Main factors which influence NNU4940MAW33 Bearing 200x280x80mm performance include, but are not limited to:
Symmetrical rollers
Symmetrical rollers self-adjust , providing optimal load distribution along the roller length. This keeps stresses low under all load conditions and extends bearing service life.
Roller tolerances
The rollers in an NNU4940MAW33 Bearing 200x280x80mm are manufactured to extremely tight tolerances for dimension and form. Each roller is virtually identical in size and shape to the other rollers in the set. This optimizes load distribution over the rollers to maximize bearing service life.
Special roller profile
The roller profile determines the stress distribution in the roller/raceway contact area. The special profile distributes loads more evenly along the rollers and prevents stress peaks at the roller ends to extend bearing service life .
Self-guiding rollers and a floating guide ring between the two rows of rollers Self-guiding rollers reduce friction and frictional heat . NNU4940MAW33 Bearing 200x280x80mm floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
Metal cages All NNU4940MAW33 Bearing 200x280x80mm contain strong metal cages. This enables them to tolerate high temperatures and all lubricants.
