RAIL LENGTH Guide Rail Length: Single rails are fabricated as standards to the lengths shown in the dimensional tables for each type and series. Unless otherwise specified, the distance to the first hole from one end of the rail (referred to as dimension "N") is within the range specified in the dimensional tables. The guide rail is therefore fabricated according to the equation given below. For other than standard dimensional requirements, contact NB. L = M P + 2N L : length (mm) N : distance to the first hole center from the end of the rail (mm) P : hole pitch (mm) M : number of pitches. Note: Slide guide rails are machined with mounting holes as depicted in Figure A-21 during the initial fabrication process (before heat treatment). Specifying a different hole pitch or size will increase the cost and lead time, so please try to avoid changing these specifications. JOINT RAILS Rails can be joined together to obtain a length which exceeds the specified maximum standard length. There are two ways to do this. Place the joints at the same location for the right and left rails so as to make the design and maintenance simple (Figure A-23 ). Place the joints for the right and left rails at different locations so that the block does not move over the two joints at the same time so as to minimize the effect of the joint on accuracy (Figure A-23 ). A-12 Figure A-21 Guide Rail Mounting Hole Figure A-22 Guide Rail Grinding Method grinding stone Please keep the following points in mind when using joint rails. To avoid dislocation at joints due to shock loading, provide a shoulder at the joint on the installation side. Use the joint marks provided. Tightly butt the rails to be joined so that there is no gap between them. Notes: The standard accuracy and pre-load grade are only available on joined rail systems. The GL type and the SER type guide series can not be made with joined rails. Contact NB for further information on joining .
