Description

Drawn cup needle roller bearings consist of a very thin outer ring and have as a peculiar characteristic a small dimension, this enables an easy fitting up everywhere is required. HK and BK are suitable for standing heavy loads and reaching very high rotation speeds, they are forced into the housing bore and do not have to be axially fixed. Thanks to the cage, rollers are driven with maximum precision. Drawn cup needle roller bearings can be assembled without IR inner ring therefore the shaft works as a raceway, in this case the shaft must keep an hardness included between 64 HRC and 58 HRC maximum load ability is assured. Under request, HK and BK can be supplied with IR inner ring. ISB needle roller bearings can be open ends or closed end, and without lubricant, in fact they are fitted with a conservative product before assembly. BK needle roller bearings are closed at one end, they are used for shaft-end mounting. Drawn cup needle roller bearings are also available with seals: this protects them from external factors and let them have an higher lubricating power (temperature has to be included within -30°C and +80°C).
