They have compact structures and high stiffness,and can carry high radial loads but not axial loads. Because of inner rings with no ribs, inner and outer ring subassembly (with full set of rollers and cage) can be mounted respectively. Cleaning, inspecting and dismounting are very convenient. Four row cylindrical roller bearings are especially applied to rolling mills required high speed and precision, for example,wire mills,bar and shape mills,cold or hot sheet mills and cogging mills. Brass solid cages or pin-type cages are mainly used in four-row cylindrical roller bearings.
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 545171 Four Row Cylindrical Roller Bearing that are used in papermaking machines. 545171 Four Row Cylindrical Roller Bearing 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, 545171 Four Row Cylindrical Roller Bearing 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
545171 Four Row Cylindrical Roller Bearing for Industrial Machinery Spherical Roller Bearings developed by integrating NSK's materials, design and manufacturing technologies.
545171 Four Row Cylindrical Roller Bearing 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.
