Overview (for your eBay description)

NSK 1206K is a double-row self-aligning ball bearing with an open design (no seals) and a 1:12 tapered bore. Both rows of balls run in a spherical outer-ring raceway, allowing the bearing to accommodate shaft misalignment and housing deformation without negatively affecting performance. Self-aligning ball bearings are known for very low friction, minimal heat generation at higher speeds, and strong radial load capacity, with the ability to carry moderate axial loads in both directions. The tapered bore (1:12) design allows mounting on tapered shafts or adapter sleeves, making installation and adjustment easier in many applications.

Typical Applications

Commonly used in:

• Electric motors and fans
• Pumps and light gear drives
• Conveyors and general machinery
• Applications where misalignment is expected and a tapered-bore mounting solution is preferred
