25、 European Standard deals with the requirements for the design and manufacture of Guide Bearings and Restraint Bearings. Guide Bearings and Restraint Bearings are not intended to transmit vertical loads but they may be combined in one unit with bearings in accordance. EN 1337-1:2000, Table 1. NOTE 1

26、Guide Bearings and Restraint Bearings are shown in EN 1337-1:2000, Table 1, No. 8.1 and 8.2. For combined bearings see EN 1337-1:2000, Table 1, bearing Nos. 1.2, 1.3, 1.6, 1.7, 1.8., 3.1, 4.1, 4.2, 4.3, 7.1, 7.3, and 7.4 with restraints and Nos. 1.5, 1.7, 2.2, 3.3, 3.4, 5.2, 6.2 and 7.3 with guides.

27、 NOTE 2 Examples of combined bearings are given in Annex B. The minimum operating temperature depends on the materials properties used at the required temperature and the limitations given in the referenced parts of this European Standard. NOTE 3 In certain circumstances the bearings described in th

28、is part of this European Standard may be required to operate in a plane inclined to the horizontal. In such circumstances the terms “vertical“ and “horizontal“ should be interpreted appropriately. 2 Normative references The following referenced documents are indispensable for the application of this
