INA PNA40/62-XL Self-Aligning Needle Roller Bearing

• Metric series
• Self-contained aligning adapter
• For static or initial misalignment
• With or without inner ring

The bearings comprise drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings. Aligning needle roller bearings are X-life bearings. These bearings have optimised raceway surfaces. This gives higher load carrying capacity and longer rating life. Needle roller bearings without inner ring: Bearings without inner ring have particularly compact radial dimensions. However, they require a shaft raceway that is hardened and ground. Needle roller bearings with inner ring: Bearings with an inner ring are used if the shaft is not configured as a rolling bearing raceway.
