New bearing range is 'permanently' impregnated with lubricant
IKO Nippon Thompson has introduced its CapiLube bearings, which are
permanently impregnated with a thermosetting lubricant. The new range is
available as a variant of all existing IKO machined and shell-type needle
roller bearings, plus cam followers, up to a maximum outer diameter of
80mm. The solid lubricant fills all cavity spaces within the bearing and
dispenses itself during rotation, in precisely controlled amounts.
A rotational durability test showed that in over 5,000 hours use, a type
TAF455520 bearing turning at a constant 400rpm and accepting an applied
load of 3,00N, suffered a minimal loss of lubricant plus a slight fall in
actual bearing temperature. A second, oscillating durability test carried
out over 3 x 107 ascillations, showed that a type TAF253316 bearing
enduring an applied load of 1,960N at a frequency of 217 cycles per
minute, produced barely any recordable change in temperature and even
less loss of lubricant than in the rotational test.
