Questions about this item

How often will the SRI 2 lubricant inside the 6309 bearing need replacement under continuous operation?

The bearing is factory-filled with SRI 2 grease and double-shielded, so it is designed for lubricated-for-life service with no scheduled relubrication interval.

What load limit determines the service life of the 6309 bearing when it runs continuously at rated speed?

The dynamic radial load capacity is 76,700 N; operating near this value will govern fatigue life under sustained use.

How much heat will the 6309 bearing generate when it runs all day at its rated load?

Heat rise depends on the actual applied load, speed, and mounting conditions, which are not fixed by the bearing itself.
