Grease life and supply intervals of UCF 213
The grease the of a packed ball bearing unit can be found using Formula(4.7).The regreasing schedule should be set at 1/4 to 1/3 of the grease life found by the calculation shown above;
8.4.1 Grease life and supply intervals
However this may be adjusted for particularly demanding environments or conditions.In addition, some environments may be unusually dirty or wet, and these conditions may be exacerbated by higher temperatures.Under such harsh conditions, a more frequent regreasing schedule will extend the life of the bearing.
Under normal operating conditions, please adhere to the guidelines outlined.

Remark Greasing intervals shown in this table are applicable to a unit operated for 8 to 10 hours perday. lf the time of operation is greater than this range, then a more frequent greasing interval must be specified. For example, if the unit is operated 16 to 20 hours per day, then the greasing interval must be twice as frequent.
