Needle roller bearing with thin and long roller (roller diameter D is less than or equal to 5mm, L / D is greater than or equal to 2.5, l is the length of the roller), so the radial structure is compact, the diameter size and load capacity and other types of bearing phase at the same time, minimum diameter, especially for radial mounting dimensions restricted support results. According to different occasions, can choose or needle roller bearings without inner ring and cage assembly. At this time with the matched bearing shaft neck surface and the surface of shell holes directly as a bearing inner and outer rolling surface, in order to ensure that the load capacity and operating performance and have the same ring bearing, shaft or housing holes roll surface hardness and machining accuracy and surface quality should be and bearing ring raceway and similar. Such bearings can only bear radial loads.
Needle roller bearing (1), closed type stamping outer ring needle roller bearings (2), with inner ring needle roller bearings (3), and without inner ring needle roller bearings / no inner ring without cage needle roller bearings (4), a cage and cage filled with needle roller bearing (5) of SKF can also supply various types of needle roller shaft bearing, needle holding frame component 2, no flange needle roller bearing 3, self regulating hearts 4, combined needle roller / ball bearing 5, combined needle roller and thrust ball bearing 6, combined needle roller / cylindrical roller thrust bearings

Drawn Cup
Needle roller bearings for roller bearing with thin metal forming the outer ring. The main characteristic is that the height of the section is very low and the load capacity is higher. The main bearing arrangements for compact, inexpensive and bearing inside the hole can not be used as the needle roller and cage assembly raceway. Bearing and bearing box shall be installed in interference fit mode. Shoulder can be avoided if the box, such as axial stop ring positioning, so the bearing inside the hole can be very simple and economic.
Mounted on the shaft end of the needle roller bearings with bilateral and unilateral closed open. The base end face of the closed stamping outer ring can bear little axial guiding force.
Needle roller bearings are generally not attached to the inner ring. The inner ring of the table can be used in the situation that the shaft neck can not be hardened and ground.
Hardened steel outer ring needle roller bearings and needle roller cage assembly can not be separated. Free space for the storage of lubricants can be extended to add lubrication intervals. Bearing is generally used in the design of a single row. Except for bearing wide specifications 1522162220302538 and 3038 series, which is equipped with two needle roller and cage assembly. Bearing outer ring with lubricating oil hole. According to user needs, shaft diameter greater than or equal to 7mm all the single stamping outer ring needle roller bearings can be equipped with lubrication holes in the outer ring (designation suffix AS1).
Needle roller bearings with seals
With oil seal stamping outer ring needle roller bearings (3 to 5) in the end due to space limitations cannot be installed to the seal of the occasion, can provide open-ended or closed. These bearings are equipped with polyurethane or synthetic rubber friction type oil seal, which is filled with good anti rust performance of lithium based grease, suitable for running temperature -20 to +100.
With the inner ring of the bearing oil seal than outer ring width 1mm, the bearings in the shaft relative bearing box with micro displacement can also ensure good seal and prevent injury to the bearing contamination. Bearing inner ring also has lubrication holes, can be based on the needs of the bearing configuration, by the outer ring or inner ring added lubrication.
