Lu­bri­ca­tion man­age­ment is im­por­tant

DEMM Engineering & Manufacturing - - FRONT PAGE -

Poor lu­bri­ca­tion is re­spon­si­ble for ap­prox­i­mately 36 per­cent of all pre­ma­ture bear­ing fail­ures. This can be a re­sult of ei­ther im­proper se­lec­tion of a lubri­cant or a re­sult of ei­ther in­suf­fi­cient or ex­ces­sive amounts of lubri­cant. Im­ple­ment­ing the right lu­bri­ca­tion so­lu­tion how­ever can lead to in­creased plant up­time and pro­duc­tiv­ity and in­crease en­ergy ef­fi­ciency.

Grease lu­bri­ca­tion is the most com­mon type used by in­dus­try al­though it can also be eas­ily mis­un­der­stood in re­gards to suit­abil­ity for an ap­pli­ca­tion, com­pat­i­bil­ity of greases and the amount of grease re­quired for spe­cific ap­pli­ca­tions. In­suf­fi­cient grease is recog­nised as an ob­vi­ous fault while ex­ces­sive amounts of grease is not usu­ally seen as an is­sue, al­though it can lead to poor op­er­at­ing con­di­tions, degra­da­tion of the grease or dam­age to seals and in­creased en­vi­ron­men­tal costs.

GREASE SE­LEC­TION

Se­lect­ing a grease can be a del­i­cate process. SKF has de­vel­oped sev­eral tools in or­der to fa­cil­i­tate the se­lec­tion of the most suit­able lubri­cant. A wide range of tools are avail­able from easy-to- use ap­pli­ca­tion based ta­bles to ad­vanced cal­cu­la­tion soft­ware such as SKF LubeS­elect to se­lect SKF greases by us­ing de­tailed op­er­at­ing con­di­tions.

If the wrong grease is used in an ap­pli­ca­tion, pre­ma­ture bear­ing fail­ure will likely oc­cur. Ad­di­tion­ally, if in­com­pat­i­ble lu­bri­cants are mixed the re­sult can also lead to un­favourable lu­bri­ca­tion lead­ing to bear­ing fail­ure.

Man­ual se­lec­tion of grease should con­sider the ro­ta­tional
