The suffix M1 of FAG cylindrical roller bearings indicates bearings with brass cages guided by rollers.
FAG cylindrical roller bearings with the suffix TVP2 have a cage made from glass fibre reinforced polyamide PA66.
Check the chemical resistance of polyamide to synthetic greases and lubricants with EP additives.
Aged oil and additives in the oil can impair the operating life of plastic cages at high temperatures. The oil change intervals must be observed.
FAG standard cages for single row cylindrical roller bearings: see table.

FAG cylindrical roller bearings Other cage designs
Other cage designs are available by agreement. In such cages, suitability for high speeds and temperatures as well as the basic load ratings may differ from the values for bearings with standard cages.
