• Sealing Technology: Reinforced Dual-Lip Contact Rubber Seals with Steel Deflector Shields

Core Engineering Advantages

• Firm Shaft Retention: The precision dual set-screw locking collar ensures tight, slip-free grip on standard 20mm transmission shafts under continuous operational cycles.

• Friction-Optimized Dynamics: Super-finished internal raceways minimize running friction, maintaining stable, lower operating temperatures at high speeds.

• Universal Housing Compatibility: Tailored for seamless drop-in installation into standard 204-series industrial pillow blocks, flange units, and take-up assemblies.

• Advanced Contaminant Defense: Factory pre-lubricated with multi-purpose grease and tightly shielded to block out dust, grit, and moisture infiltration.

Typical Operational Sectors

• Material Handling & Conveyance: Roller conveyor systems, belt drive assemblies, and sorting machinery.

• Agricultural & Processing Equipment: Small grain augers, agricultural fans, and sorting tables.

• Industrial Automation & Motors: Fractional horsepower electric motors, textile machinery, and packaging lines.
