Appendix E
The correct choice of oil and grade is essential to obtain the best performance and life from the gear unit.
Using too heavy a grade than required will result in reduced efficiency; whilst using too light a grade of
oil will result in premature wear. If in doubt, ask Renold Gears Technical Department.
If the gear unit is operating below the catalogue rating at a temperature below 60
o
C, then a light grade oil
should be used. Medium grade oils should be used when operating up to the catalogue rating with
temperatures up to 100
o
C. Heavy grade oils should be used at temperatures in excess of 100
o
C under
heavy loading. However, if the unit is operating at gear rubbing speeds
below
2.5 metres/sec (500
ft/min), then the next higher grade should be used than that which would normally be selected.
If required, a list of recommended food grade oils is available on request.
