01E 01 Series Enhanced Split Cylindrical Roller Bearings: Radial load capacity is increased by approximately 30% compared to the basic 01 series. Patented self-locking cage provides greater lifespan and safety margin. Size interchangeability is available.

B Inner ring with tapered locking sleeve: Quick clamping and positioning, excellent centering, strong anti-loosening, efficient assembly and disassembly, and reduced maintenance costs.

400 Imperial Inner Diameter 4″ (101.6 mm): Corresponds to metric 101.6 mm, designed for heavy-duty medium-diameter shafts.

EX Floating (Expansion) Type: Outer ring without flanges, bears only radial loads, allows free axial movement of the shaft, adapts to thermal expansion and contraction, and avoids additional stress.

Fully Split Structure: The inner ring, outer ring, rollers, and cage are all split in half, allowing for assembly and disassembly without disassembling the shaft or adjacent components, significantly reducing downtime and making it suitable for shaft-constrained scenarios (such as between the head pulley of a belt conveyor and a reducer). Cooper Bearings.

Upgraded Load Capacity: Radial load capacity is increased by approximately 30% compared to the basic 01 series. The self-locking cage optimizes roller arrangement, improving rated life and safety margin, making it suitable for heavy-duty applications.

Floating Design (EX): Bears only radial loads, allowing free axial movement without additional stress, perfectly adapting to shaft thermal expansion and contraction, avoiding stress damage to equipment.

Conical Locking Sleeve (B): Quick locking and positioning, excellent centering, strong anti-loosening capability, efficient installation and disassembly, reducing maintenance costs.

Size Interchangeability: Can directly replace older 01 series bearings of the same specifications; no modification to existing housings required, resulting in low upgrade and modification costs.

Relubrication Capability: Equipped with a standard 1/8″ NPT lubrication hole for easy on-site grease replenishment, extending service life.
