Wire/cable tubular strander use cylindrical roller bearing N1056MC3P5 280X420X33MM
We/JinHang precision bearing orrer radial cylindrical roller bearings can offer higher radial load capacity than other bearing designs. The offers a wide range of full complement, one -, two -, and four-row designs to meet various application requirements.
cylindrical roller bearings consist of an inner and outer ring, a roller-retaining cage, and a complement of controlled- contour cylindrical rollers. Depending on the type of bearing, either the inner or the outer ring has two roller-guiding ribs. The other ring is separable from the assembly and has one rib or none. The ring with two ribs axially locates the position of the roller assembly. The ground diameters of these ribs may be used to support the roller cage. One of the ribs may be used to carry light thrust loads when an opposing rib is provided. The decision as to which ring should be double ribbed is normally determined by considering assembly and mounting procedures in the application.

The full-complement (NCF) single-row bearings include integral flanges on the inner and outer rings. These bearings also can manage axial loads in one direction and permit small axial
Two-row, or double-row, cylindrical bearings offer added radial capacity over tradition one-row types. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. The standard cage design is a drilled pocket, finger-style retainer
Four-row cylindrical bearings have an extremely high radial load capacity, but no thrust capacity. This bearing type is mostly used in roll neck and work roll applications in the metal rolling industry. Straight and tapered bore designs are available.
In a cylindrical roller bearing, the rollers and racewaysare in linear contact. Consequently this type of bearing can support a larger radial load than a point-contact ball bearing. Also, its structure is suitable for high-speed operation.
A cylindrical roller bearing used for the main spindle of a machine tool can have either a double- or singlerow configuration, and certain variants have a tapered bore so the radial internal clearance can be adjusted.
Double-row cylindrical roller bearings
Double-row cylindrical roller bearings are available in two types, NN and NNU, and two series, 30 and 49.The rollers in the NN type bearing are guided by the ribs of the inner ring. The rollers in the NNU typebearing are guided by the ribs of the outer ring.
Bearings are available with either a tapered bore type (which allows adjustment of radial internal clearance of bearing) or a standard cylindrical bore. The bearings come in two types, standard type and high-speed HS type. Standard cage is machined brass
