5.1 Material compatibility
Lubricants must be compatible with the following materials:
" steel, grey iron, brass, copper, aluminium
" NBR, FPM, ABS, PA, PU
5.2 Ageing of lubricants
After a prolonged downtime of the machine, the lubricant may no longer be suitable for use due to chemical or
physical ageing and must therefore be inspected before the system is recommissioned. We recommend in-
specting the lubricant already after a week’s downtime. If you suspect that the lubricant is no longer suitable,
replace it prior to recommissioning and, if necessary, perform initial lubrication manually. It is possible for lubri-
cants to be tested in SKF's laboratory for their suitability for being pumped in centralised lubrication systems
(e.g. no “bleeding”). Please contact SKF if you have further questions regarding lubricants. An overview of the
lubricants tested by SKF is also available upon request.
