DHK four row cylindrical roller bearings are produced either solid brass cages or pin-type steel cages.

DHK four row cylindrical roller bearings are produced to the normal tolerance class (PN) or closer tolerance class such as P6 or P5 upon request.

Detailed tolerance values are listed in tolerance of radial bearings. Page 8.
