Needle roller bearing
Needle bearings equipped with a fine and long rollers, the radial structure is compact, therefore, when the diameter size and load bearing capacity the same as the other types, outer diameter is the smallest, in particular the installation of the application with the radial size of the supporting structure restricted. According to the use of different occasions, can use the non-inner needle bearing or use needle and cage assembly.
   Drawn up needle roller bearing   ( back to top )
Drawn Cup Needle Roller Bearings are precision sheet steel extrusion, the outer ring of 400-600 degrees by 1.3 degrees high temperature carburization of high toughness Cage guided needle group G2 group, and its radial cross-section very small, and with the overall load capacity, especially suitable for use in the economic category of a large number of products. Drawn Cup Needle Roller Bearings with outer ring of the bearing box used surplus with the rest, no axial fixtures. Even in the high-speed, high load conditions, but also to ensure that their flexible working performance. Drawn Cup Needle Roller Bearings advanced closure principle is that the body fat volume, and the long term without lubrication, as a result of high temperature lubrication intervals, thus ensuring its long-term worry-free operation. Drawn Cup Needle Roller Bearings in general do not have inner circle, because of its design will normally be a reasonable choice of IR-type inner Drawn Cup Needle Roller Bearings Bearings are divided into two ends of perforation (HK-type) and closed end bearings (BK-type). Drawn Cup Needle Roller Bearings Bearing seal one end of a closed structure, applicable to shaft end and can withstand small Axial momentum.

   Single direction needle roller bearing   ( back to top )

According to the different needs of internal and external changes in a flexible structure, its outer ring is made from alloy steel precision stamping, after special treatment to enhance the wear resistance of the load-bearing capacity is extremely, retainer to guide the use of high toughness PA66 2m needle to obtain a better precision bearing steel and the rotating performance and maximum torque transmission.

The design allows the perfect one-way bearing | needle bearing one-way | one-way clutch needle in -30 to 120 temperature range of long-term operation. The advantage is that when one-way bearing | needle bearing one-way | one-way clutch needle side of the direction of the arrow shaft rotates relative self-locking clutch.

   Needle roller thrust bearing ( back to top )
Needle Roller Thrust Bearings are both have a form-stable cage to reliably guide and retain a large number of needle rollers. The diameter deviations of the rollers within one assembly are within 2 μm. Due to this, the bearings accommodate heavy axial loads and shock loads. These bearings provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components can serve as raceways and the space that needle roller thrust bearings take up no more space than a conventional thrust washer.
