Needle bearing-deep groove ball bearing NJA59 and DNJB59
Non-separable and transmit axial loads in both directions with an axial clearance of 0.1 to 0.3mm
Standard grade bearing
For all bearings supplied, the dimensional tolerances and geometric precision are in compliance with DIN620 and the tolerance grade of P0 with normal radical gap CO. The only exception is NKIB series which have narrower inner aperture with bigger tolerance so that they can be used with the shaft with K5 tolerance in transit combination.
Table 1 shows the tolerances applicable to the fitting for general purposes:

1) In bearing hole, the diameter of the thrust bearings must be 0.5mm bigger than nominal diameter D1 or D2 to avoid interference combination.
2) To ensure normal functions, no closer combination than k5 shaft and M6 hole should be used
Special requirements
If the bearings combination is of high precision, the listed bearings in compliance DIN 620 P6 AND P5 grades tolerances can be supplied.
For NKIA and NKIB series bearings, only the bearings with initial radical gap between C2 to C3 can be supplied.
