Bearing width: the axial spacing between the end faces of the two ferrules that limit the width of the radial bearing; the single-row tapered roller bearing refers to the axial spacing between the opposite side of the outer ring and the opposite side of the inner ring.
Bearing height: The axial spacing between the opposite sides of the two washers that limit the height of the thrust bearing.
Ball diameter: the spacing between two parallel planes that are tangent to the outer surface of the ball.
Roller diameter: in the plane perpendicular to the axis of the roller axis (radial plane); the interval between two tangent lines that are tangent to the outer surface of the roller. When calculating the extra load; use the diameter of the middle of the roller To the plane.
Roller length: The interval between two radial planes including the end of the roller. However, the "roller length" used to calculate the extra load is the theoretical maximum touch length of the roller and raceway at the shortest touch.
Nominal inner diameter (outer diameter): enveloping the diameter of the cylinder of the theoretical cylindrical inner bore (cylindrical outer and outer surface) theoretical appearance. In a specified radial plane; the diameter of the cone of the outer surface of the envelope conical bore. The spherical diameter of the theoretical appearance of the fundamental spherical appearance.
The nominal width of the ferrule: the spacing between the two theoretical end faces of the bearing ring. It is usually the reference value of the practice width error (fundamental scale).
Bearing practice width: the spacing between the axial line of the radial bearing and the intersection of the two tangent planes of the ferrule practice end face that limits the bearing width. Limit the bearing width with the inner ring end face and the outer ring end face.
Note: For single-row tapered roller bearings; the spacing between the bearing axis and the intersection of the two planes: one plane is the plane tangent to the opposite side of the inner ring practice; the other is the plane tangent to the opposite side of the outer ring practice. At the moment, the inner and outer ring raceways and the inner side of the inner ring are in contact with all the rollers.
Bearing practice height: the spacing between the axial axis of the thrust bearing and the washer that limits the height of the bearing.
Ball nominal diameter: usually used to identify the diameter of the ball scale.
Nominal diameter of the roller: the diameter value usually used to identify the diameter of the roller. Regarding the symmetrical roller; the theoretical diameter in the radial plane passing through the middle of the length of the roller; the largest theoretical diameter for the asymmetric roller (ie In a radial plane including the concealed sharp corners of the large end of the tapered roller).
Rolling bearing public service: under normal conditions; at +20 ° C temperature; bearing and its parts do not cause internal stress due to external force (including measuring load and part's own gravity); its size scale should not exceed the nominal scale error scale.
