01E: 01 series enhanced split cylindrical roller bearing, with significantly improved load capacity and life compared to the basic 01 series;

B: Inner ring with tapered locking sleeve, ensuring reliable shaft positioning/locking, good alignment, and easy installation;

212: Imperial inner diameter 2-3/4″ (69.85 mm);

EX: Expansion (floating), outer ring without flanges, bearing only radial loads, allowing for free axial expansion and contraction of the shaft (maximum approximately 7 mm).

Structure and Core Features:

Fully Split: The inner ring, outer ring, rollers, and cage are all split in half, allowing for assembly and disassembly without removing the shaft or adjacent components, significantly reducing downtime;
Self-Locking Steel Cage: Sturdy structure, high temperature resistance, and high operational reliability;
Floating Design (EX): Bears only radial loads, allowing for free axial movement to accommodate shaft thermal expansion and contraction, avoiding additional stress;
Conical Locking Sleeve (B): Quick clamping and positioning, strong anti-loosening capability, and efficient installation and disassembly;
Relubricated: Equipped with lubrication holes for convenient maintenance and extended service life;
Interchangeable Size: Can directly replace older 01 series bearings of the same specifications without modification to existing housings/cartridges.
