1726205-2RS1 Spherical Outer Single Row Insert Ball Bearing Double 2RS1 Contact Seal 25x52x15mm Conveyor Farm Machinery
The 1726205-2RS1 spherical outer ring insert ball bearing is built on deep groove ball bearing structure with spherical convex outer surface and double-sided 2RS1 NBR reinforced contact rubber seal. The spherical outer surface delivers built-in self-aligning function to compensate shaft and housing assembly deflection; dual contact seals block dust, crop residues and light water splashes. It bears radial load plus moderate bidirectional axial load, widely matched to medium-duty conveyors, agricultural implements, packaging lines and general industrial machinery with dusty, vibrating working environments.

???? Full technical data and drawings available upon request
- Spherical outer ring self-aligning design eliminates abnormal friction and premature wear caused by shaft-housing installation misalignment
- Dual-sided 2RS1 metal-backed rubber contact seal forms tight isolation barrier against workshop dust, farm soil and splash water, locking internal long-life grease inside
- Higher axial load capacity than ordinary insert bearings, stable under composite radial & light axial alternating load
- Stamped steel cage with high rigidity, stable low-noise continuous medium-load operation, not easy to deform under vibration
- Standard metric universal dimension, perfectly compatible with standard cast iron & pressed steel bearing housings for quick field replacement
- Optional variants: open non-sealed version, C3 enlarged clearance for high-temperature heavy vibration working scenarios
- Compact medium-size structure balances sufficient load capacity and space-saving installation for conveying and agricultural machinery
???? Reduce unexpected equipment downtime caused by shaft misalignment and foreign contamination, lower long-term maintenance expenditure
- Medium-duty automated conveyor roller supporting assemblies
- Small & medium agricultural tractors, seeders, lawn mowers and farm harvesting auxiliary transmission shafts
- Packaging production line rollers, textile processing equipment and ventilation fan rotary components
