Needle roller bearing features :( Description)
1. ??High Speed
2. Can withstand high radial load (other than the radial bearings to bear the same size as the radial load large)
3. Can not withstand the axial load
4. Rigid higher
Needle roller bearings are cylindrical roller with a roller bearing, relative to its diameter, both the thin and long rollers. Such as needle roller. Despite the smaller cross section, has a higher load bearing capacity, therefore, especially for the occasion radial space is limited.
Contour surface in the proximal surface of needle at a slight contraction. Needle and roller contact with the modified line results can be destructive to the edge to avoid stress. In addition to catalogs listed in the bearing can be used for general engineering, such as: open type Needle roller bearings
(1), closed Needle roller bearings
(2), needle roller bearings with inner ring
(3) And non- needle bearing inner ring
(4) SKF can supply all types of needle roller bearings, are: 1, needle roller cage assemblies 2, needle roller bearings without ribs 3, self-aligning roller bearings 4, Combined needle roller / ball bearings 5, combined needle roller / thrust ball bearings 6, combined needle roller / cylindrical roller thrust bearings.
Needle roller bearings with a thin metal forming the outer ring of needle roller bearings. Its main characteristic is exposed to a low sectional height higher load capacity. Mainly used in compact, cheap and needle roller bearing inside the hole can not be used as components of roller cage bearing configuration. Bearing and bearing housing must be installed by interference fit. If you can save me the shoulder, axial positioning stopper ring and other features, then the bearing hole can be done inside a very simple and economic.
Mounted on the shaft of the Needle roller bearings have bilateral open type (1) and one side closed (2). The base closed end drawn cup can withstand small axial guiding influence.
