Industrial-Strength HC205 Insert Bearing | 25mm Bore x 52mm OD x 17mm Width with Dual Set Screws

📋 Technical Specifications & Dimensions

• Series / Model: HC205 (Equivalent to GRA025-NPP-B, RA025RR)

• Bore Diameter (Inner d): 25 mm

• Outer Diameter (Outer D): 52 mm

• Total Thickness / Width (B): 17 mm (Extended wide inner ring profile)

• Material Architecture: High-Carbon GCr15 Chrome Steel

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

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

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

🌟 Key Engineering Highlights

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

• Optimized Load Distribution: The widened inner ring profile 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 205-series pillow blocks, flanged housings, and take-up units 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

• Industrial Automation & Conveying: Medium-duty roller conveyor systems, sorting tables, and automated packaging lines.

• Agricultural Machinery: Grain augers, combine harvester auxiliary drives, and tractor implement rollers.

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