8x21mm Thrust Needle Bearing 8x21x4mm Miniature

Thrust Needle Roller Bearing - Single Unit
✔️ 8mm ID x 21mm OD x 4mm Thick for axial load support

This thrust needle roller bearing is built for handling heavy axial loads in compact spaces. With a slim 4mm profile and strong load ratings, it’s perfect for applications like gear assemblies, turntables, or any rotating setup with limited radial space. The needle rollers allow for higher capacity and stiffness compared to traditional ball thrust bearings.

✅ Pack size: 1 bearing

💡 Why choose a thrust needle roller bearing over a ball thrust bearing?
Thrust needle bearings are optimized for high axial loads in tight spots where standard ball bearings would fail or take up too much room.

• Compact yet heavy-duty for dense mechanical setups

• High stiffness under load makes them great for precise movement

• Ideal for gearboxes, tool spindles, and rotating platforms

• Outperforms ball-style thrust bearings in thin layouts

If you're upgrading or building for strength in a tight axial space, this bearing will punch way above its weight. Add one to your cart and let your gear turn smoother than ever!
