01E: 01 Series (Medium Load) + E = Reinforced / Standard Split Structure

B: Split Cylindrical Roller Bearing

45: Inner Diameter d = 45 mm (Metric)

M: Metric Size Standard

GR: Locating/Fixed, capable of withstanding medium axial loads in one direction (fixed shaft end)

Fully Split Design (Biggest Selling Point): The inner ring, outer ring, rollers, and cage are all split in half, allowing for direct assembly/disassembly on the shaft without removing adjacent components such as couplings, gearboxes, pulleys, and motors. Downtime is reduced from hours to tens of minutes.

Load and Positioning Capacity: Cylindrical roller line contact provides high radial rigidity and low friction, suitable for medium loads and medium-to-high speeds.

GR Positioning Type: Capable of withstanding radial and unidirectional axial forces, used to fix the shaft end and limit axial movement.

Installation and Maintenance: Pre-set clearance eliminates the need for on-site adjustments; installation is simple and requires no special tools.

Compatible with Cooper’s dedicated split bearing housing (01EC45MGR), featuring a triple labyrinth seal for dust and water resistance, suitable for harsh operating conditions.

Operating Condition Adaptability: High temperature resistance (-20℃～+120℃), dust resistance, and moisture resistance make it suitable for continuous operation and environments with limited maintenance space.
