1726208-2RS1 Spherical Outer Single Row Insert Ball Bearing Double 2RS1 Contact Seal 40x80x18mm Conveyor Farm Machinery
The 1726208-2RS1 spherical outer ring insert ball bearing adopts convex spherical outer surface and double-sided 2RS1 metal reinforced contact rubber seal. The spherical outer ring features automatic self-aligning function to compensate shaft and housing assembly deflection, while dual contact rubber seals effectively block dust, crop residues and splashing water. It bears radial load plus slight bidirectional axial load, widely applied to medium-duty conveyors, agricultural implements, packaging lines and general industrial machinery operating in dusty, vibrating working environments.

???? Full technical data and drawings available upon request
- Spherical outer ring self-aligning design avoids abnormal abrasion and premature failure caused by shaft misalignment during assembly
- Dual-sided 2RS1 multi-lip reinforced seal forms tight isolation barrier to prevent workshop dust and farm mud from invading, locking long-life lubricant inside bearing cavity
- Stamped steel cage has high structural rigidity, resistant to deformation under long-term vibration and delivers stable low-noise rotation
- Excellent medium composite load capacity, stable under continuous alternating radial and light axial load
- 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
- Moderate 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 deflection, cut long-term equipment maintenance cost
