• Imperial Bore Size: 1-1/4 Inches (1.250" / 31.75 mm)

• Outer Diameter: 72 mm

• Overall Thickness / Width: 20 mm (Extended wide inner ring profile)

• Material Composition: High-Carbon GCr15 Chrome Steel

• Locking Technology: Dual Socket Set Screws (Offset configuration for maximum shaft clamping bite)

• Ring Geometry: Spherical Outer Surface (Compensates for initial angular offset and structural deflection)

• Sealing Configuration: Heavy-Duty Dual Rubber Contact Seals with Metal Guards

🌟 Key Engineering Highlights

• Slip-Resistant Clamping: The dual set-screw mechanism bites deeply into the shaft upon tightening, eliminating rotational play and axial drift under continuous heavy load cycles.

• Optimized Stability Profile: The widened inner ring evenly distributes radial and tilting loads, shielding the shaft assembly from premature wear and stress fatigue.

• Universal Housing Compatibility: Designed to drop smoothly into standard 207-series pillow blocks, flanged housings, and take-up assemblies without modification.

• Advanced Contaminant Shielding: Factory pre-lubricated with high-performance industrial grease and guarded by double-lip contact seals to block out abrasive dust, dirt, and moisture.

⚙️ Primary Deployment Sectors

• Agricultural Machinery: Combine harvesters, heavy grain augers, and tractor implement drivelines.

• Industrial Conveying Systems: Heavy-duty roller conveyors, material sorting lines, and aggregate handling equipment.

• General Mechanical Units: Industrial ventilation blowers, fan assemblies, and commercial gear transmission systems.
