💡 What is a double-row roller bearing used for in industrial linear slide units?

These bearings are handy for applications that need extra radial strength and sealed protection. Quick summary:

- Supports higher radial loads than single-row bearings, great for conveyors and heavy machinery - Works well in linear slide unit systems that need sealed bearings or sealed ball bearing alternatives - Oil hole allows on-site relubrication for longer service life in dusty or wet environments - Suited for heavy-duty, uncaged setups where compact footprint and load capacity matter
