01: Series designation, medium load capacity (02 Heavy Duty, 03 Extra Heavy Duty)

E: Split cylindrical roller structure (upgraded from the E series, offering superior load capacity and lifespan)

B: Standard design

75: Inner diameter 75mm

M: Brass cage (patented design, high strength, wear resistance, low noise)

EX: Expansion (axial movement/thermal expansion type), allowing for thermal expansion of the shaft; fixed type is GR

Fully split design: The inner and outer rings, rollers, and cage are all in two halves, allowing for assembly and disassembly without removing the coupling/gearbox, significantly reducing maintenance time.

Load characteristics: Primarily designed for heavy radial loads; the EX type allows free axial movement of the shaft, suitable for high-temperature thermal expansion conditions.

Bronze cage (M): Patented design of the E series, with optimized roller arrangement, significantly improving load capacity and rated life.

Interchangeability: Dimensions are consistent with the older 01/02 series; direct replacement without modification of the bearing housing/chuck.
