6205-2RS Bearings 25x52x15mm Ball Bearing Double Rubber Sealed Shielded For 3D Printer

6205-2RS deep groove ball bearings, inner diameter: 25mm, outer diameter: 52mm, thickness: 15mm.

6205RS bearing is made of high-precision bearing steel, which is resistant to rust, deformation and good stability under heavy load.

Double Rubber Seal prevent the leakage of lubricant in the bearing and prevent the intrusion of external dust, moisture, 

foreign matter and other harmful substances. Support harsh environment use.

6205 2RS bearings are widely used in agricultural machinery, conveying equipment, robots, elevators, ship rudder shafts, 

skateboards, and inline skates.

6200 series 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
