    what is best,a machine we use in the food industry, cycles at
    30rpm a direct
    drive cam opperates a lifter that travels 500mm up and
    down, the machine is washed down every night,there is
    no particulate matter.
    so would linear bearings or bushes be best for lifter?

    I'd go with a bushing. My personal experience with linear bearings is that the races move unless precise allignment is maintained. If there's a lot of side thrust a bushing would have to be replaced more often.

    thanks for reply GENIERE.
    i have come to the same conclusion,linear brgs are excelent
    in well maintained enviroment ,but in harsh wet food industry
    bushes seem to last up to three times longer.
