JIS_Spring

Special Springs 6 springs selection The following selecting guide-line is essential for an easy and fast selection of the springs. Please specify the following working parameters: expected lifetime (ex.: 3.000.000 cycles), hole diameter (ex.: 16 mm), total spring force (ex.: 380 N) and total spring working deflection including pre-load (ex.: 5 mm). Once selected the total springs deflection (ex.: 5 mm) select the corresponding spring code (ex.: R 16 - 025). The bigger the pre-load the longer the lifetime of springs for the same total deflection (% of Lo). The intersection of the expected lifetime with the hole diameter shows different forces. Select the one closest to your need. After selecting the proper force box (ex.: 380 N) look to the corresponding load range of springs (ex.: R - heavy load). Then go to the standard tabs on the column A corresponding to the expected lifetime of 3.000.000 cycles and select the required total spring deflection. Through the tabs on pages 7 and 8 cross the expected lifetime section (ex.: 3.000.000 cycles) with the hole diameter required (ex.: 16 mm). EN EN EN EN EN EN
