Description

NOTE: Please refer to the picture and select right type of bearings before your order (Sealed or Shield on BOTH or SINGLE side of the bearing). Suffix on the bearing just for differentiating between Sealed and Shield type of bearing. It would not affect the use of our product. Description: Single-row, pre-lubricated, normal accuracy. Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance. These cost- effective bearings are widely used in areas with low requirements for Mohs hardness. Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on. Selecting Guide: Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris. Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.

We used these for rc cars and they worked as expected. Metal shielded would be a little better for the wheels as tangled up grass can often wrap around the axles and damage the plastic shielded type but these are very affordable.

Perfect. Exactly what I wanted! Not very tough, but how tough can balls that small really be anyway? Am I right? I use them in knives, and they work perfectly. Well machined and inexpensive. Fast delivery. 💯
