7 Dimensions

7.1 General Whether there is a relubrication device on the seat is optional. If a lubrication device is provided, the lubrication area of the device should be in accordance with GB/T 3882. The specified bearing lubrication zones intersect so that the lubricant is smoothly injected through the bearing housing into the bearing lubrication zone. The outer dimensions of the bearing housing are shown in Tables 1 to 10. The "max" in Table 1 to Table 10 indicates that the value is both the nominal value and the maximum allowable measured value. "min" in Table 1 to Table 6 indicates This value is both the nominal value and the minimum allowed value. 7.2 casting seat The outer dimensions of the casting seat are shown in Tables 1 to 8. Cast square seat (F200 type), cast diamond seat (FL200 type), cast boss round seat (FC200 type) and cast ring seat The outline dimensions of (C200 type, C300 type) are shown in Appendix A, Appendix B, Appendix C, and Appendix D.
