💡 Customer Tip - When should you choose shielded bearings over sealed ones?
Answer: Shielded bearings (ZZ) are ideal when you need protection from light contamination and want lower rolling resistance for high-speed applications. They're great for enclosed environments like electric motors or tools where exposure to debris is minimal.
⚙️ Compact, efficient, and built for speed - R8ZZ shielded bearings deliver consistent reliability for a wide range of motorized and mechanical applications.
Bearings were great. Customer service even better.
They delivered on time, bearings were for a drag knife for a CNC and they work perfect. Would definitely order from vxb again.
Bearing were decent quality for the price. Will need to buy a better quality bearing in the future. The bearing had a tendency to lock up when pressed into the bearing housing. Had to increase the diameter of the housing to get the bearings to spin correctly. But can't complain as these were for a prototype. Good value to prove the concept. If you could suggest a bearing of higher quality of the same size please submit to [****] Thx.
Worked Great
These are some of the best bearings I've found - ever! They are exactly dimensioned and work perfectly and I certainly will use VXB for any bearing needs I have in the future!!
