(1)Mounting surface roughness is less than Ra12.5.
(2)The maximum allowable values of the installation surface flatness can be determined according to bearing actual working condition, but the flatness change must be uniform increasing or decreasing, within the scope of the circumference of a circle, not allowed to appear more than two (including two) peak, and 100 mm face runout is not allowed within the scope of more than 0.015 mm
(3)Maximum value on the radial direction inclination of the mounting surface is 0.04mm .
(4)Prestressing force of bolt installation must be determined according to the strength level of the bolt,the pre load force is 0.7 times to the bolt material yield limit.
