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 surface) is fitted with general bearings in the seat holes, basic stable load C and C0 should be used while used as rolling wheel, rated load Cw and Cow should be used.3) the rotating speed will increase by about 30% if oil lubricant is used.
