💡 What is a spherical bushing used for in pillow block and linear slide unit shaft support? A spherical bushing gives self-aligning shaft support under heavy radial and misalignment loads, making it a handy choice for many industrial setups. Quick overview: - Provides misalignment compensation and heavy-duty radial support, sometimes used where sealed ball bearing replacements are considered. - Commonly fitted in pillow block housings and linear slide units for conveyors, presses, and rotating shafts with moderate contamination. - If low friction or contamination sensitivity is critical, consider sealed ball bearing or ceramic alternatives for improved performance.
