Replacement Bearings Your maintenance program will not be complete without including
spare bearings. It must be remembered that the bearing is a wearable
component and therefore must eventually be replaced. To ensure that
you are able to maintain original operation, we recommend the
purchase of spare parts directly from Allen-Bradley.
All bearings are subject to exact specifications and tests necessary to
satisfy performance requirements. In this manner, it is possible to
duplicate your present bearing. Markings on the bearing do not
indicate complete specifications.
!
ATTENTION: Mixing lubricants is not recommended due
to possible incompatibility. If changing lubricant without
motor disassembly is desired, follow lubrication
instructions and repeat lubrication after 100 hours of
service. Care must be taken to look for signs of lubricant
incompatibility, such as extreme “soupiness” visible from
the grease relief area. Failure to observe this precaution
could result in damage to or destruction of the equipment.
Standard Conditions: Eight hours per day; normal or light loading, clean, 40 degree C
(100 degrees F) maximum ambient.
Severe Conditions: Twenty-four hour per day operation or shock loading, vibration, or in
dirt or dust at 40-50 degrees C (100-120 degrees F) ambient.
Extreme Conditions: Heavy shock or vibration, or dust.
