Products Description
Temperature limits
The permissible operating temperature for deep groove ball bearings can be limited by:
The dimensional stability of the bearing rings and balls
The cage
The seals
The lubricant
Where temperatures outside the permissible range are expected, contact NMN.
Bearing rings and balls
NMN deep groove ball bearings are heat stabilized up to at least 120 °C (250 °F).
Cages
Steel, stainless steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls. For temperature limits of cages made of other polymer materials, refer to Polymer cages.
Seals
The permissible operating temperature for seals depends on the seal material:
NBR: -40 to +100 °C (-40 to +210 °F)
Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
FKM: -30 to +200 °C (-20 to +390 °F)
Temperatures up to 230 °C (445 °F) can be tolerated for brief periods.
Typically, temperature peaks are at the seal lip.
Lubricants
Temperature limits for greases used in NMN deep groove ball bearings capped on both sides are provided in table 1. For temperature limits of other NMN greases, refer to Selecting a suitable NMN grease.
When using lubricants not supplied by NMN, temperature limits should be evaluated according to the NMN traffic light concept.
