Product Description

Description:Four row cylindrical roller bearing for interference fit on the roll neck

Type:531839 Four row Cylindrical roller bearing Dimension:340X480X370 mmMetic ID(inner diameter)Bore:340 mm OD(outer diameter):480 mm WidthHeightthickness:370 mm Fw:378 mm Number of roller:Four row Quantity: One Bearing Dynamic load rating Cr: 5300 KN Static load rating Cor: 11000 KN Weight:210 kgs The forging material:GCr15SiMn GCr15,G20Cr2Ni4A (Case hardened steel ) The cage type: Brass solid cages or pin-type cages The delivery time:20-30 days The package:standard export wooden case or carton boxes. 531839 Four-row cylindrical roller bearings are the one of the main bearings for rolling mills.They mount for interference fit on the roll neck. 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 531839 Four Row Cylindrical Rollerr Bearing that are used in papermaking machines. 531839 Four Row Cylindrical Rollerr 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, 531839 Four Row Cylindrical Rollerr 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
531839 Four Row Cylindrical Rollerr Bearing for Industrial Machinery Spherical Roller Bearings developed by integrating NSK's materials, design and manufacturing technologies.
531839 Four Row Cylindrical Rollerr 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.

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 531839 Four Row Cylindrical Rollerr Bearing 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 531839 Four Row Cylindrical Rollerr Bearing 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 . 531839 Four Row Cylindrical Rollerr Bearing floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
Metal cages All 531839 Four Row Cylindrical Rollerr Bearing contain strong metal cages. This enables them to tolerate high temperatures and all lubricants.
