Shielded-type Deep Groove Ball Bearings - 600ZZ Series
Overview:
In a deep-groove radial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.
Made of high quality bearing steel or stainless steel and different from cheap carbon steel, these caged deep groove ball bearings run very smoothly with low friction while maintaining good load capacity. They are popular on RC and robotic products.

Difference between ball bearing steel and carbon steel:
1). Material cost: ball bearing steel is about 50% higher;
2). Life span: bearings made of ball bearing steel last longer than those made of carbon steel;
3). Wear-resisting property: ball bearing steel has very strong wear-ability, while carbon steel is generally heat-treated on its surface and not hard enough;
4). Ball bearing steel has very good elasticity, fatigue strength, strong anti-friction and loading capacity, while carbon steel does have those desirable advantage points;
5). Bearings made of bearing steel run very smoothly without noise, while those made carbon steel have mechanical noise when rolling.
