The structure of ring needle roller bearing and tolerance

Entity ferrule needle bearing can bear larger load. Such bearings with inner ring and inner ring, G2 grade needle assembly, the average diameter of upper and lower deviation within the 2 um, high rigid retainer, correctly guide the needle parallel to the axis. 1. NK without inner ring needle roller bearing structure form, light NKI needle bearing series, light series NKS without inner ring needle roller bearing, heavy NKIS needle bearing series, series of heavy RNA48, RNA49 without inner ring needle roller bearing, the size series of 48,49 RNA69 without inner ring needle roller bearing, size series 69, double row NA48, NA49 needle roller bearing, the size series of 48,49 NA69 needle roller bearing, size series 69, double row GD also produce HJ, BR, etc, when need please contact in GD. 2. Radial clearance of the needle roller bearing radial clearance, samples are available for the needle roller bearing bearing clearance generally all is '0' group, also can provide the C2 and C3 or C4 group clearance. 3. Fit tolerance when installing a needle roller bearing, usually with a tight fit. With no inner ring of the shaft and the shell hole needle bearing with tolerance is associated with radial clearance, such as tolerance and radial clearance on the inner hole of shell, such as casing hole tolerance for K6. The shaft tolerance shown in the following table. Shaft is the nominal size of size tolerance shaft acuities were 80 & gt; 80 radial clearance is less than 0 K50 group normal h5g5 is greater than 0 g6f6 jiaxing bearing co. , LTD.
