1218 Self Aligning Ball Bearing 90mm Bore 160mm Outer Diameter 30mm Width Spherical Outer Raceway For Misalignment Compensation With Smooth Rotation And High Load Capacity Ideal For Precision Machinery

1218 Self-Aligning Ball Bearing 90x160x30 mm overview
✔️ 90x160x30 mm chrome steel, dynamic 56,800 N, static 23,400 N

The 1218 Self Aligning Ball Bearing features a spherical outer raceway that lets the balls and cage keep rotating even when the shaft and housing are not perfectly aligned. This makes it ideal for machinery where shaft misalignment and housing deflection are common, such as conveyors, gearboxes, and rotating assemblies. It’s built from durable 52100 alloy steel (chrome steel) for long life and reliable performance in demanding environments.

💡 What is a self-aligning bearing used for in heavy machinery?

This type of bearing handles misalignment and deflection, helping keep shafts spinning smoothly. Use case: absorbs shaft misalignment in rotating equipment for quieter operation Best fit: conveyor rollers, gearboxes, and machinery with housing flex Maintenance tip: ensure proper lubrication and regular inspection of bearing clearance and seals Performance note: supports high dynamic loads with consistent rotation and longer service life
