SKF 6215 TC C783 single-row deep groove ball bearing. Bore 75 mm, outside diameter 130 mm, width 25 mm. Straight bore, open on both faces, one row of balls carried in a machined phenolic cage that rides on the outer ring lands.
6215 places the bearing in the 6200 medium dimension series at a 75 mm bore, giving the 75 x 130 x 25 mm envelope. The T element denotes a fabric-base laminate phenolic cage; the same bearing’s legacy MRC designation, M215K CR, carries CR for an outer-land-riding phenolic cage, so the two schemes agree. C783 is an SKF special-execution suffix carried here as a carton marking.
A machined phenolic cage is light, self-lubricating and quiet, and riding on the outer ring lands keeps it stable at high speed, which is why phenolic-caged deep groove bearings are specified for grinding spindles, machine-tool quills and high-speed pumps. The trade-off is temperature: laminate phenolic is limited well below the range a brass or steel cage tolerates, and it is not suited to steam or hot water service.
One bearing. Open on both faces, no shields, seals or snap ring groove.
Standard practice at this bore is an interference fit on the shaft and a location fit in the housing, with mounting force applied squarely to the ring being fitted. Phenolic cages absorb oil, so a cage that has been stored dry is normally soaked in the service oil before assembly. Open bearings take their lubrication from the housing.
The 75 x 130 x 25 mm envelope is shared by every brand’s 6215, so a 6215 from SKF, NSK, FAG, NTN or Koyo fits the same seats. Cage execution changes the speed and temperature limits, so a standard pressed steel 6215 and a machined brass 6215 M are related sizes on the same envelope rather than identical parts.
