4、O UDC 621.822.6:531.223.001.24 JAPANESE INDUSTRIAL STANDARD J I S Static Load Ratings for Rolling Bearings B 1519-1989 1. Scope This Japanese Industrial Standard specifies the methods of calculating the basic static load ratings and static equivalent loads for rolling bearings, hereinafter referred
5、to as the llbearingslf. Remarks 1. This Standard applies to the bearings manufactured in ac- cordance with a high level manufacturing technics, of which shapes of rolling contact surfaces are basically of usual design and having usual hardness, by using the material in accordance with JIS G 4805 or
6、that material capable of attaining equivalent static load rating to this. 2. The methods of calculation in accordance with this Standard, in the case where considerable discontinuity exists on the contact surfaces between the rolling elements and the raceway track due to service conditions and (or)
7、internal design (for example, ball bearings with filling slot) , are not applicable as far as unmodified. 3. In the case where the load distribution inside the bearing is not normal (for example, misalignment, preload or excessive internal clearance exists) , this Standard may not be applicable as f
8、ar as unmodified. 4. In the case of a construction where the roliing elements roll around the outer peripheral surface of a shaft or the inner surface of a housing directly, this Standard shall not be applied, unless the raceway track thereof is equal to that of a bearing. 5. The double row radial b
9、earings and double direction thrust bearings to which this Standard applies shall be the bearings of symmetrical type. 6. This Standard is in accordance with IS0 76-1987 (Rolling bearings-Static load ratings) , as appropriate. - - Applicable Standards : JIS B 0104-Glossary of Terms Relating to Rolli

Definitions For the purposes of this Standard, the following definitions apply, and others are in accordance with JIS B 0104. (1) static loads are not in rotation
12、to each other. Loads acting on a bearing of which inner and outer rings Informative Reference: In the static loads, there are a static radial load and a static central axial load where the line of action of the load aligns with the bearing central axis. (2) basic static radial load rating A static r
13、adial load which corresponds to the calculated contact stress, as given in the following, at the centre of contact of the rolling element and the raceway track being subiected to the maximum load. Self-aligning ball bearings: 4600 MPa Other radial ball bearings: 4200 MPa Radial roller bearings: 4000
14、 MPa Remark: In the case of a single row angular contact ball bearing and a single row tapered roller bearing, this basic static radial load rating means the radial component of that load which permits a pure radial displacement to cause relatively between the both bearing rings. Informative Referen
15、ce: The total permanent deformation of the rolling elements and raceway track to be caused under these contact stresses amounts approximately to O. O001 time the diameter of rolling bearings. (3) basic static axial load rating A static central axial load which cor- responds to the following calculat
16、ed contact stress, as given in the following, at the centre of contact of the rolling elements and the raceway track being subjected to the maximum load. Thrust ball bearings : 4200 MPa Thrust roller bearings: 4000 MPa Informative Reference: The total permanent deformations of the rolling elements a
17、nd raceway tracks to be caused under these contact stresses amount approximately to 0.0001 time the diameter of rolling bearings. (4) static equivalent radial load A static radial load which permits the centre of contact of the rolling elements and the raceway track being subjected to the maximum lo
18、adto generate the same contact stress as that which is generated under the actual loading conditions. ( 5 ) static equivalent axial load A static central axial load which permits the centre of contact of the rolling elements and the raceway track being subjected to the maximum load to generate the s
19、ame contact stress as that which is generated under the actual loading conditions.

For a tapered roller, the diameter concerned shall be an arithmetic mean value of diameters at the theoretical corners of the
21、 larger end and the smallar end of a roller. 2. For an asymmetrical convex surface roller, the diameter concerned shall be an approximation of the diameter at the contact point between the roller at no load and the raceway track without flange (normally, an outer ring) . (7) effective length of roll
22、er The length of the shorter one, among the contacting lengths of the roller with the inner ring or outer ring. Remark: The effective length of the roller shall normally be a subtracted dimension of the roller chamfer from the length of roller and the subtracted dimension of the grinding allowance f

(8) nominal contact angle An angle included between the vertical plane to the central axis of the bearing and the nominal line of action of the resultant force of the transmitting forces from the raceway ring to the roiling elem
