1726209-2RS1 Spherical Outer Single Row Insert Ball Bearing Double 2RS1 Contact Seal 45x85x19mm Conveyor Farm Machinery

The 1726209-2RS1 spherical outer ring insert ball bearing comes with convex spherical outer surface and double-sided 2RS1 metal reinforced contact rubber seal. The spherical outer ring delivers automatic self-aligning performance to offset assembly deflection of shaft and housing, while dual contact seals block dust, crop residues and splashing water effectively. It bears radial load plus slight bidirectional axial load, widely used for medium-duty conveyors, agricultural machines, packaging equipment and general industrial machinery under dusty and vibrating working conditions.

👉 Full technical data and drawings available upon request

• Spherical outer ring self-aligning design avoids abnormal abrasion and premature damage caused by shaft misalignment during installation
• Dual-sided 2RS1 multi-lip reinforced seal forms tight isolation barrier to prevent workshop dust and farm mud intrusion, locking long-life lubricant inside bearing cavity
• Stamped steel cage features high structural rigidity, not easy to deform under long-term vibration, realizing stable low-noise rotation
• Balanced medium composite load capacity, reliable for continuous alternating radial and light axial load operation
• Standard metric universal dimension, perfectly matched with standard cast iron and stamped steel bearing housings for quick field replacement
• Optional variants: open non-sealed version, C3 enlarged clearance for high-temperature heavy vibration working conditions
• Reasonable overall size balances sufficient load capacity and space-saving installation for medium conveying and agricultural machinery

👉 Reduce unexpected equipment downtime caused by foreign contamination and assembly deviation, lower long-term equipment maintenance expenditure
