Rod end bearings of type W (self-lubricating) can be used from -50 °C to +200 °C. In general, use at higher temperatures is possible, but this reduces the service life. Load values Load values are bearing related values, derived from the material data of the material used. They are used to select a rod end bearing for a given load, but may have to be reduced in case of special operating conditions. Static load values Co in kN Co indicates the permitted radial load at standstill which a rod end bearing at its weakest cross section can withstand without causing permanent deformation when the load is at rest. The Co values listed in the catalog tables have been calculated based on the respective material characteristics and were verified on a representative number of rod end bearings in a tensile test at room temperature. An 80% utilisation of the yield strength was applied in each case, so that a safety factor of 1,25 is included. The static load value Co is also used to determine the permissible axial load , which is primarily limited by the axial fixing of the internal ring. Tests were carried out to determine the permissible axial load Fa at the largest tilting angle: Fa = 0,4 Co for type N Fa = 0,2 Co for types NH, W, WH, WK d 1 GN 648.1 / GN 648.2 GN 648.5/.6 GN 648.8 GN 648.9 Size Type N Type W Type NH Type WH/WK Type N Type W Type WK  5 2,5  7,5 3,3 7,5  3,3   7,5   7,5  6 3,2  9,3 4,3 9,3  4,3   9,3   9,3 8 5,4 16,7 7,1 16,7  7,1  16,7  16,7 10 7,5 23,4 10 23,4 10  23,4  23,4 12 10 32 13,5 32 13,5  32,0  32,0 14 13 42 17 42 17  42,0  42,0 16 16 52,5 21,5 52,5 21,5  52,5  52,5 18 19,5 64 26 64 26  64,0  64,0 20 23,5 78 31,5 78 31,5  78,0  78,0 22 29 97 38 97 38  97,0  97,0 25 35 122 47 122 47 122 122 30 64 168 64 168 64 168 168 Ball Joint Heads DIN ISO 12240-4 / DIN ISO 12240-1, Series K Technical Information d 1 GN 648.1 GN 648.2 GN 648.5 GN 648.6 GN 648.8 GN 648.9 Size Type N Type W Type N Type W Type NH/WH/WK Type NH/WH/WK Type N Type W Type WK  5  9,9  8  4,3  4,3 11,8 6,2  19,8  12,5  12,5  6 11,9  8,9  6  6 13,1 8,8  25,8 15,5  15,5 8 17,1 14,1 11 11 20,7 16,1  42,6 27,8  27,8 10 21,4 19,3 17,4 17,4 28,3 25,5  60  39,0 39,0 12 27 23,5 25,5 23,5 34,5 34,5  80  53,5 53,5 14 24,5 21 24,5 21 39,5 39,5 102,5 70  70 16 37 32 36,5 32 60,5 60,5 128,5 88  88 18 43 38,5 43 38,5 73 73 157 106,5 106,5 20 49,5 44 49,5 44 83 83 188,5 130 130 22 57 53 57 53 100 100 229 162 162 25 68 62 68 61 118 118 293 204 204 30 82 82 82 82 155 155 381 281 281 Dynamic load value C in kN They help to determine the service life of dynamically stressed rod end bearings.
