2、Inspection on dimensions
Special attention：
Because the thin stamped external ring has a deformation after heat treatment, its dimensions cannot be accurately inspected before installation. The bearing''s dimension can reach its necessary geometric accuracy only after the bearing has been pressed into the standard seat hole .
The deviation of inscribed circle''s diameter(Fw) of needle bearing with stamped external ring shall comply with the stipulation in table 1:

Nominal internal diameter of needle assembling unit Fw(mm)		Fw min=Fw min-Fw
greater than	up to	upper limit of tolerance	lower limit of tolerance
3	6	+28	+10
6	10	+31	+13
10	18	+34	+16
18	30	+41	+20
30	50	+50	+25
50		+60	+30

The inspection method: press the bearing into the standard seat hole that has a dimension complying with table 2 and has a thickness greater than 20;then use the limit plug gauge listed in table in table 3 to make a measurement.

Nominal internal diameter of needle assembling unit Fw (mm)		Nominal internal diameter of standard ring	Tolerance of standard ring um	Wall thickness of standard ring
greater than	up to

3、Installation
The needle bearing with stamped external ring can get its final dimensions and geometric accuracy only after it has been pressed into the seat hole .The tolerance of seat hole and shaft is recommendded in table 4. When it uses the journal as the rolling race , its surface hardness cannot be lower than 58HRC; its surface roughness Ra shall be less than 0.2um; its roundness and cylindricity shall not greater than 50% of the journal''s dimensional tolerance.
