Outer Diameter: 72 mm

Overall Width (B): 20 mm (Extended wide inner ring for superior stability)

Alloy Composition: High-Carbon GCr15 Chrome Steel

Locking Mechanism: Dual Socket Set Screws (Staggered layout for maximum shaft grip)

Outer Ring Contour: Spherical Surface (Compensates for initial angular misalignment)

Sealing Technology: Heavy-Duty Double-Lip Rubber Seals with Metal Guards

💎 Structural Performance Benefits

Anti-Slip Shaft Anchoring: The dual set-screw system bites securely into the shaft when torqued down, completely eliminating rotational play and axial drift under heavy cyclic loads.

Optimized Force Dispersion: The broadened inner ring distributes radial and tilting loads evenly along the shaft, minimizing localized stress and extending component service life.

Plug-and-Play Compatibility: Precision-crafted to slide smoothly into standard 207-series pillow blocks, flanged housings, and take-up assemblies with zero modification required.

Robust Environmental Barrier: Factory pre-lubricated with high-grade industrial grease and tightly guarded by contact seals to block out abrasive dirt, moisture, and agricultural debris.

🚜 Typical Operational Sectors

Agricultural Machinery: Heavy-duty combine harvesters, high-capacity grain augers, and tractor implement drivelines.

Bulk Material Handling: Aggregate conveyor systems, heavy-duty sorting rollers, and automated processing lines.

Industrial Infrastructure: Commercial blowers, large fan assemblies, and heavy mechanical power transmission drives.
