💡 What is a pillow block bearing used for in a linear rail system?

A handy overview of its role in keeping things aligned and moving smoothly:

• pillow block bearing supports the slider and absorbs misalignment on a linear rail
• preload adjustment helps keep tight tolerances and reduces play
• works with standard SBR16 rails for reliable CNC and automation setups
• improves lifetime by stabilizing the moving carriage and reducing vibration
