💡 What is a spherical plain bearing used for in shaft alignment and heavy pivot applications? They provide a load-bearing pivot that tolerates misalignment and high radial forces in industrial shafts. Quick summary:

- Ideal for heavy shaft alignment and pivot joints where sealed ball bearing or ceramic options may not fit - Commonly used in housings, pillow blocks, and linear slide unit setups for durable metal-on-metal performance - Useful when high temperature (up to 180°C), shock loads, or very high static capacity are required
