1726306-2RS1 Spherical Outer Single Row Insert Ball Bearing Double 2RS1 Contact Seal 30x72x19mm Conveyor Farm Machinery
The 1726306-2RS1 spherical outer ring insert ball bearing adopts convex spherical outer surface and double-sided 2RS1 metal-reinforced contact rubber seal. The spherical outer race realizes automatic self-aligning function to compensate installation deflection of shaft and housing. Dual contact seals effectively isolate dust, farm mud, crop debris and splashing water. It bears large radial load and obvious bidirectional axial load, widely matched to medium-heavy conveyors, harvesting equipment, packaging production lines and industrial machinery running in dusty and severe vibration environments.

Full technical data and drawings available upon request
- Spherical outer ring self-aligning design eliminates abnormal friction and premature wear caused by shaft and housing assembly misalignment
- Dual-sided 2RS1 reinforced multi-lip seal forms tight protective barrier, preventing foreign matter intrusion and locking 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 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
