1726308-2RS1 Spherical Outer Single Row Insert Ball Bearing Double 2RS1 Contact Seal 40x90x21mm Conveyor Farm Machinery

The 1726308-2RS1 spherical outer ring insert ball bearing is designed with convex spherical outer surface and double-sided 2RS1 metal-reinforced contact rubber seal. The spherical outer race provides automatic self-aligning capacity to compensate shaft and housing assembly deflection; dual contact seals fully block dust, farm mud, crop residues and splashing water. It supports heavy radial load and obvious bidirectional axial load, widely used for medium-heavy conveyors, agricultural harvesting equipment, heavy packaging lines and industrial machinery running in dusty and severe vibration environments.

• Spherical outer ring self-aligning structure eliminates abnormal friction and premature wear caused by shaft-housing installation misalignment
• Dual-sided 2RS1 reinforced multi-lip seal forms tight protective barrier, prevents foreign matter intrusion and retains long-life lubricant inside bearing cavity
• Excellent medium-heavy composite load capacity, stable under long-term alternating radial and axial impact load
• High strength polymer cage resists deformation under continuous vibration, delivers low noise and stable high-load rotation
• Standard metric universal dimension, perfectly compatible with standard cast iron and stamped steel bearing housings for quick field replacement
• Optional configurations: open unsealed version, C3 enlarged clearance for high-temperature heavy vibration working conditions
• Larger outer diameter structure greatly improves load carrying capacity without excessive installation space occupation

???? Reduce unexpected equipment downtime caused by contamination and assembly deviation, effectively lower long-term maintenance costs

This sealed self-aligning medium-heavy load insert bearing is widely applied to:

• Medium-heavy duty automated conveyor heavy roller supporting assemblies
• Agricultural harvesters, medium tractors, seeders and soil preparation machinery transmission shafts
• Heavy-duty packaging line rollers, large textile equipment and industrial large ventilation fan rotary parts
• Small construction mixing machinery and general medium-heavy load industrial transmission equipment
