3811B2RSRTVH Solid Polyamide Snap Cage Angular Contact Ball Bearings, Sealed
The 3811B2RSRTVH Double-row deep groove ball bearings are widely used in equipment requiring a compact structure and bidirectional axial load capacity, such as automotive wheel hubs, industrial gearboxes, electric motors, agricultural machinery, crane pulleys, and conveyor equipment.
The 3811B2RSRTVH bearing is a Angular contact ball bearings Double row sealed with an inner diameter of 55 mm , an outer diameter of 72 mm, a width of 13 mm. It typically uses PN grade precision tolerances and bearing steel rings, bearing steel rolling mlement. Its dynamic radial rated load is approximately 12066 N, its static radial rated load is approximately 15693 N. It uses CN standard radial clearance, 2RSR = Lip seals on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
3811B2RSRTVH bearings ( 55 mm x 72 mm x 13 mm) have the advantages of High speed, low noise, low friction, and are therefore widely used in the Electric motors, industrial pumps, compressors, automobile wheels, and agricultural machinery.

The 3811B2RSRTVH Double-row deep groove ball bearings mainly consist of an integral inner ring, an integral outer ring, two rows of balls, and a cage. The raceways are deep grooves, with the balls making four-point contact with the raceways. The inner and outer rings are typically integrated, resulting in a compact structure.
A single set of double-row deep groove ball bearings can simultaneously withstand radial and bidirectional axial loads, eliminating the need for paired installation. They offer higher load-carrying capacity than single-row deep groove ball bearings and excellent rigidity. The integral structure simplifies installation, saves space, and is suitable for applications requiring high axial positioning.
