Single 40mm stainless steel set screw ball bearing, sealed deep groove for linear slide units, machinery and motor replacements, corrosion resistant radial part for precision motion

Single 40mm stainless steel set-screw ball bearing for motion
✔️ 40mm bore stainless steel, set-screw lock, sealed deep groove radial

This single sealed stainless steel set-screw ball bearing is a deep-groove radial unit used in linear slide units, motors, conveyors and general industrial machinery where corrosion resistance and secure shaft locking are required.

✅ Single bearing (1 piece) for straightforward replacements and repairs
✅ Metric size: 40mm bore suitable for precision radial loads
✅ Material: stainless steel construction for corrosion resistance
✅ Locking: set-screw shaft retention for secure mounting
✅ Seal type: sealed deep-groove design for dirt protection and longer life

💡 Why choose sealed ball bearings for linear slide units? Sealed ball bearings help keep grit and grime out, lower maintenance needs, and support smooth, low-friction motion in linear slide units and similar gear. Quick intro: - Improved contamination protection from sealed ball bearing design increases uptime and extends service intervals - Stainless option offers corrosion resistant performance for damp or outdoor applications, while ceramic variants can reduce friction and boost speed - Ideal for linear slide unit setups, conveyor systems, motors and other radial-load applications where secure set-screw locking helps prevent shaft slippage
