Nachi 5201-2NS Angular Contact Ball Bearing (Lot of 4)

The Nachi 5201-2NS is a high-precision double-row angular contact ball bearing designed for applications requiring combined radial and axial load support. With dimensions of 12mm bore, 32mm outer diameter, and 15.9mm width, this sealed bearing (2NS designation indicates non-contact rubber seals on both sides) provides excellent protection against contaminants while maintaining low friction and high-speed performance. It is commonly used in industrial machinery such as pumps, compressors, gearboxes, and electric motors, where it excels in handling bidirectional axial loads and moderate radial loads. Benefits include superior rigidity, reduced vibration, and extended service life due to Nachi's advanced manufacturing with high-quality steel and precise ball contact angles (typically 30 degrees). Compared to similar products from competitors like SKF or NSK, the Nachi 5201-2NS offers competitive pricing with reliable Japanese engineering, though it may have slightly lower load ratings in extreme high-speed scenarios. Drawbacks include the need for proper alignment to avoid premature wear. Based on attached images, this lot of 4 appears new and unused, stored in original packaging with no visible damage or wear. Serial or batch numbers like 'C3 180921' are noted on boxes, indicating clearance class C3 for higher temperature operations. No parent/child assets are evident. For detailed specs, refer to Nachi's official bearing catalog (available at nachi.com). Estimated shipping dimensions are for the lot in combined packaging.
