The deep groove ball bearings from DCDC have deep and continuous raceway grooves. They are various, self-retaining bearings with solid outer rings, inner rings, ball and cage assemblies. These products are made of simple design, easy-to- maintain, durable in operation. They are available in single and double row designs in both open and sealed variants. Due to the production technology used, the open bearings can still have turned breaks up on the outer ring for shields or seals. On the other end due to their frictional torque they are meant for high speeds.
