01: Serial number (medium load split cylindrical roller bearing)

B: Split single-row cylindrical roller bearing (bearing body only)

180: Inner diameter code (corresponds to 7-1/8 in / 180.98 mm)

M: Represents improved design (optimized roller distribution, improved load-bearing and impact resistance)

EX: Expansion (floating/expansion type), allows for thermal expansion and contraction of the shaft, but cannot withstand axial loads.
