⚙️ Technical Specifications & Industry Matrix

Bearing Part Number: HLR-2 (Heavy-Duty Track Roller / Cam Follower Bearing)

Precise Physical Dimensions:

Inner Diameter (Bore - d): 20 mm (0.787 in)

Outer Diameter (OD - D): 72 mm (2.835 in)

Overall Width / Thickness (B): 22 mm (0.866 in)

Equipment & Machinery Compatibility: Universal fit for heavy-duty agricultural balers, track rail systems, material handling conveyors, and industrial power transmission equipment requiring a 20x72x22mm roller assembly.

⚡ Structural Advantages & Heavy-Duty Performance

Thick-Walled Outer Ring Architecture: Specially hardened, heavy-profile cylindrical outer ring designed to withstand continuous high-impact rolling contact against guide tracks without deformation or fatigue flaking.

Superior Contamination Defensive Barrier: Heavy-duty multi-lip contact seals protect the internal raceways against dry crop dust, straw particles, moisture, and abrasive soil grit.

Maintenance-Free Synthetic Pre-Lubrication: Pre-filled at the factory with high-grade wide-temperature agricultural synthetic grease, eliminating daily greasing downtime and lubricant washout.

High Dynamic Load Capacity: Precision-ground GCr15 chrome steel construction provides exceptional resistance against high radial shock forces and operational torque.

🚜 Agricultural & Industrial Machinery Deployment

Baler Plungers & Guide Tracks: Ideal replacement guide roller bearing for square baler plunger mechanisms and hay harvesting implements operating under heavy reciprocating impact.

Conveyor & Material Handling: Essential track roller component for industrial automated conveyors, sorting machinery, and heavy guidance rails.

Severe-Duty Agricultural Machinery: Designed for field implements working in harsh, dusty, damp, or abrasive environments.
