TN=plastic
retainer ,permissible operational temperature
120,150 for temporary use,180 for short
time only .1)F is the inner ring tray diameter
, Fw is the needle incircle diameter within
the tolerance range F6.2)When the bearing
outer ring (with outer cylindrical sruface)is
fitted with general bearings in the
seat holes ,basic stable load C and C0 should
be used while used as rolling wheet , rated
load Cw and Cow should be used .3)the rotating
speed will increase by about 30% if oil
lubricant is used.
