The method of bearing designation for Cylindrical Roller bearings typically consists of three parts: prefix, basic code, and suffix. Here’s an explanation of the designation method used by BRZB:
1.N: Represents single row cylindrical roller bearings.
2.NN: Represents double row cylindrical roller bearings.
The basic code follows the same format as other bearings. It consists of a type of code at the beginning, followed by size (width series), and then the inner diameter series.
Material code:
·RS: GCr15/SUJ2 rings and rolling elements.
·RXH: GCr15/SUJ2 rings with Si3N4 rolling elements.
Cage Material Codes:
·TB: PA66
·TP: PEEK
·MB: Brass alloy
·MR: Brass alloy with max. operation temperature 300°
Inner Ring Shape:
·-: normal cylindrical inner ring(no suffix)
·KR: Tapered inner ring
Clearance code:
·CC1: standard clearance for normal inner ring.
·CC0: standard clearance for tapered inner ring.
·CCG: special clearance.
Please note that bearing designation methods may vary from country to country, and the above explanation is specific to the BRZB designation method for cylindrical roller bearings.
