Questions about this item

How often should the 21313 K bearing be re-lubricated?

Relubrication intervals depend on operating speed, load and temperature; consult NTN guidelines for the 65 mm bore, 140 mm outer diameter, 33 mm width unit.

What temperature limit applies to the 21313 K under continuous load?

The bearing’s steel and cage materials set the thermal limit; sustained operation above NTN’s rated temperature for this 65x140x33 mm size reduces life.
