6004 bearing 6004ZZ 42x20x12mm C3 Clearance chrome steel deep groove ball bearings

6004 bearing 6004ZZ 42x20x12mm chrome steel deep groove ball bearings is the most common type of rolling bearing. 

The basic deep groove ball bearing consists of an outer ring, an inner circle, a set of steel balls and a set of maintenance frames.

6004 bearing 6004ZZ 42x20x12mm chrome steel deep groove ball bearings type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal. 

The dust - proof sealing material is a sheet metal stamping, which simply prevents the dust from entering the bearing roller. The oil-proof type is the contact oil seal, which can effectively prevent the grease spillover inside the bearing.

Single row deep Groove Ball Bearings offer multiple options that serve a wide range of applications. The 'groove' is the depth of the raceway into which the balls fit, they typically consist of an Inner Ring, Outer Ring, Balls and Cage. Variants are available with Steel Shields, Rubber Seals (Contact/Non-Contact type), Snap-ring Grooves with Snap-rings, and a variety of Cage types. 

These Bearings are designed for radial, axial, and also composite load applications, purpose of deep groove precision ball bearings is to reduce rotational friction and support radial and axial loads.Deep Groove Ball Bearings offer:

·Uni or bi-directional load carrying capability

·Very high-speed rotation

·Very good running accuracy

·Low noise and low friction torque
