Single 25mm narrow ball bearing with zinc wide set screw, white thermoplastic housing; slim-profile unit for linear slide systems, sealed option compatible with ceramic upgrades and precision motion

Single 25mm narrow ball bearing, zinc white housing
✔️ Single unit, 25mm bore, zinc wide set screw, white thermoplastic housing

This single 25mm narrow ball bearing features a zinc wide set screw and a white thermoplastic housing. It's typically used in linear slide units, small machinery, conveyors, and precision motion assemblies.

✅ 25mm inner diameter, narrow profile for tight fits
✅ Zinc wide set screw for secure shaft locking
✅ White thermoplastic housing resists abrasion and moisture
✅ Single bearing pack for one replacement or prototype builds
✅ Compatible with sealed ball bearing setups and ceramic upgrades

💡 What is a sealed ball bearing used for in linear slide units? Sealed ball bearings reduce friction and block contaminants so linear slides run smoother and last longer. Here's why that matters: - Improves precision in linear slide unit and motion systems with low-friction rolling elements - Keeps out dust and debris to extend life of narrow bearings and thermoplastic housings - Pairs well with ceramic upgrades or sealed ball bearing swaps for higher speed and lower wear
