01E: 01E series (enhanced split cylindrical roller bearing, with higher load capacity than the 01 series)

B: Double row cylindrical roller structure (primarily for radial loads)

45: Inner diameter d=45mm (suitable for shaft diameters)

M: Brass solid cage (ring-guided, wear-resistant, low-noise, and stable under heavy loads)

EX: Expansion (floating type), the inner ring has no axial locating groove, allowing free axial movement during thermal expansion and contraction of the shaft; the corresponding fixed type is GR.

Split Design (Core Advantage)
The inner/outer rings, rollers, and cage are all split in half, allowing for installation/replacement without disassembling the shaft or adjacent components, significantly reducing downtime.

No realignment is required after assembly, simplifying maintenance.

EX Free-Sliding Feature
The inner ring has no locating grooves, allowing the shaft to slide freely axially during thermal expansion and contraction, preventing thermal stress jamming. Suitable for continuously operating equipment with large temperature variations, such as fans, pumps, and conveyors.

Double-row Rollers: High radial load capacity, able to withstand impact and vibration.

Cage and Operating Conditions
Brass M Cage: High strength, suitable for medium-to-high speed and continuous operation scenarios.

Wide applicable temperature range, factory-preset clearance, ready to use upon installation.
