Findbearing.com supplies high quality NK needle roller bearing without inner ring.
Note:
– Entity bushed needle roller bearing is a kind of high capacity bearing with small sectional height.
– It can operate flexibly even with the light alloy bearing seat due to the high hardness of the outer ring.
– NK series is the light series needle roller bearing without inner ring. The shaft surface will be the raceway for the needles.
– It is requested that the surface hardness be no less than HRC60 and the surface roughness be no more than 0.63um.
– TN means plastic retainer.
– Permissible operating temperature: 120 centigrade, 150 centigrade for temporary use, 180 centigrade for short time only.
– For grease lubricant, the permissible value should be 60% of those in the list.
