Cylindrical Roller Bearings
EM Series
NSK has developed a higher load-carrying capacity
machined cage with low noise and superior cage strength.
Our EM series is a standard cylindrical roller bearing
that facilitates interchangeability across the globe, while
offering better performance for every application.

EM Series
Advantages of a
roller-guided cage
Trouble-free packing
of grease
Quieter operation
Improved oil flow
A newly developed standard bearing
•

•
Greater accuracy of the roller
guidance achieved through
special pocket profiling
Large pocket corner radii
relieve stress concentrations
on the cage

NSK has been supplying a standard cage for single row cylindrical roller bearings as
indicated here:
Standard machined cage
High load-carrying E type
M type (Riveted-type, two-piece, brass, ring-guided cage)
MA1 type (One-piece, brass, ring-guided cage)
You can now take advantage of NSK’s newly developed cylindrical roller bearing,
the EM series, which combines the strengths and technologies of both previous cages
into a one-piece brass roller-guided cage.
NSK has achieved a new design involving even newer concepts, while maintaining
excellence in function and service life. Our EM series can meet your high load-carrying
capacity needs for the new era.
