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 500857A Four Row Cylindrical Roller Bearing With Tapered Bore that are used in papermaking machines. 500857A Four Row Cylindrical Roller Bearing With Tapered Bore 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, 500857A Four Row Cylindrical Roller Bearing With Tapered Bore 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
500857A Four Row Cylindrical Roller Bearing With Tapered Bore for Industrial Machinery Spherical Roller Bearings developed by integrating NSK's materials, design and manufacturing technologies.
