The comparison between positioning preload and constant pressure preload is as follows: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
(1) When the pre-tightening amount is flat; the positioning pre-tightening has a greater effect on the bearing rigidity; and the influence of the rigidity change on the bearing load during positioning pre-tightening is also much smaller.
(2) Positioning pre-tightening in operation; axial length difference due to temperature difference between shaft and bearing housing; large amount of radial expansion caused by temperature difference between inner and outer rings; displacement caused by load; The amount changes, while the constant pressure preload is in use; the change in preload is negligible.
