💡 What is a spherical bushing used for in linear slide units and heavy machinery?

Theyre a handy choice for aligning shafts and handling heavy radial or misaligned loads. Quick overview:

- Provides self-alignment for shafts in linear slide units and pillow block setups, reducing shaft stress - Works as a sealed ball bearing alternative when metal-on-metal contact and high load capacity are needed - Compatible with systems that may later upgrade to ceramic or hybrid components for low-friction needs - Common in conveyors, presses, and heavy machinery where load, heat tolerance, and simplicity matter
