The NA206-19G is a heavy-duty radial insert ball bearing engineered for reliable performance in demanding industrial environments. Featuring a spherical outer ring and an extended inner ring with an eccentric locking collar, this bearing is designed to mount quickly onto standard shafts and deliver long service life in pillow block, flange, and take-up housing assemblies.

The outer ring carries a 19 mm width with a spherical grinding surface that self-aligns inside the housing, compensating for initial shaft misalignment and mounting errors. A lubrication hole and grease groove are machined into the outer ring, allowing easy re-greasing through the housing fitting without disassembly, which extends maintenance intervals and keeps downtime to a minimum. Both sides of the bearing are fitted with effective contact seals that retain the factory-applied high-quality lithium complex grease and block out dust, moisture, and other contaminants.
