🛠️ Engineering Parameters & OEM Directory

• Series Model Designation: HC209-28 (1-3/4" Bore Architecture)

• OEM Cross-Match Reference List: G1112KRRB, UEL209-112D1, YEL209-112, VE-228, NA209-28, UG209-28, INS-SXR-112, RA028RR

• Imperial Inner Bore Size: 1-3/4 Inches (1.750" / 44.45 mm)

• Outer Diameter: 85 mm

• Overall Thickness / Width: 22 mm (Extended wide inner ring profile)

• Alloy Composition: High-Carbon GCr15 Chrome Steel

• Locking Mechanism: Dual Socket Set Screws (Staggered configuration for superior shaft clamping bite)

• Outer Ring Contour: Spherical Surface (Accommodates initial structural angular misalignment)

• Sealing Configuration: Heavy-Duty Double-Lip Rubber Contact Seals with Steel Flingers

✨ Advanced Performance Benefits

• Zero-Slip Shaft Anchoring: Dual set screws bite tightly into the shaft upon tightening, neutralizing rotational play and axial shifting during heavy cyclic load shifts.

• Balanced Load Distribution: The widened inner ring profile spreads radial and tilting forces evenly along the shaft, minimizing localized stress points and prolonging service life.

• Drop-In Housing Compatibility: Precision-engineered to slide effortlessly into standard 209-series pillow blocks, flanged housings, and take-up assemblies with zero modification required.

• Rigid Environmental Shielding: Factory pre-lubricated with high-temperature industrial grease and tightly guarded by contact seals to block out abrasive dust, moisture, and debris.

⚙️ Target Operational Environments

• Heavy Agricultural Implements: Combine harvester auxiliary drives, high-capacity grain augers, and heavy tractor machinery.

• Industrial Bulk Handling: Aggregate conveyor systems, heavy-duty sorting lines, and automated bulk transfer units.

• Commercial Drive Units: Large industrial ventilation blowers, fan banks, and processing gear trains.
