China cylindrical roller bearings NU5244M made for rolling mills, single wrapped in a wooden case and ready for shipment in 2 days. Size of NU5244M bearings are 220X400X133.4mm,Mass 79.38kgs.
Backing bearing mainly used for cold cluster rolling mill's roller. This mill take the bearing's outer ring as working surface, generally there's 3 or 5set bearings mounted on each roller and even more, depending on its matching rule. The bearing has thick outer ring and thin inner ring, high accuracy up to abec-7.
Cylindrical roller bearing based on two or three rows of rollers and are available as full complement bearings (without cage) or as caged bearings. The advantage of the bearings without flanges lies in their particularly simple geometrical form and their very high radial load carrying capacity. Cylindrical roller backing bearings without flanges or flange rings cannot accommodate any axial load. So it is necessary to position thrust washers of bronze or plastic between the side faces of the outer ring and the support saddles.
Thrust washers are not required with backing bearings with flanges (or flange rings) as the design of these bearings enables them to accommodate simultaneously acting radial and axial forces.
For different requirement, zsj's backing bearing could fall in 2 classes by material: vacuum-degassed bearing steel and electroslag cemented bearing steel. Combined with advanced heat-treatment, grinding process, the bearing's quality is highly reliable.

Sendzimir mill rolling bearing
This bearing has been specially developed for cold rolling mills of the cluster type, but can also be used for other applications, e.G. Straightening or bending machines. This bearing is a roller bearing has a particularly thick-walled outer ring and can be mounted on stationary support shafts to form back-up or straightening rolls. The forces from the work rolls are transmitted via the support shaft and a system of support saddles to the roll or machine stands. The bearing for cluster mills is produced in many designs but is generally based on double or three-row cylindrical roller bearings. Single row needle roller bearing and
Double row tapered roller bearing designs are also available. The logarithmic contact profile between rollers and raceways produces a vastly improved stress distribution under all load conditions as well as when the bearing is misaligned under load. An optimized finish on all surfaces in contact serves to enhance lubrication conditions. As lubricant is supplied to the bearings via the support shaft, the bearings have lubrication holes and some have one or more annular grooves in the inner ring.

Four row cylindrical roller bearings as rolling mill bearings are mainly used on rolling mill stands, calenders and roller presses. The four rows of rollers lends itself to carry large radial loads, but no thrust capacity, for the given bearing cross section. Four row cylindrical roller bearings are separable, the rings and rolling elements could be separated, it is convenient to wash, check, mount and dismount. Four-row cylindrical roller bearing can only bear radial load; therefore, they must be installed with groove ball bearings or angular contact ball bearings, it will be the latter which bear the axial load. our row cylindrical roller bearings are classified into FC, FCD, FCDP types.
Type FC four row cylindrical roller bearing consists of two outer rings and one inner ring, which have two ribs on outer rings, a center rib in the middle, and the inner ring without rib.
Essentially, type FCD four row cylindrical roller bearing is formed by two type NN type of double row cylindrical roller bearings, so it has double outer rings, double inner rings, and the inner ring without rib.
Type FCDP four row cylindrical roller bearing consists of two outer rings and two inner rings, which have two ribs on outer rings.
Type FC, FCD and FCDP four row cylindrical roller bearings permit axial displacement in double directions of the housing relative to the shaft. Therefore, they are suitable to be used as non-locating bearings. Normally, their cages are made from solid machinery.
Focus-6100 butyl tapes are mainly made of butyl rubber with excellent performance in waterproofing and sealing.
