4308BB.TVH Deep Groove Ball Bearings, Double Row
The 4308BB.TVH 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 4308BB.TVH bearing is a Deep groove ball bearings, Double row with an inner diameter of 40 mm , an outer diameter of 90 mm, a width of 33 mm. GCr15SiMn rings, Its dynamic radial rated load is approximately 66927 N, its static radial rated load is approximately 47931 N. It uses CN standard radial clearance, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Interchange code: 4308BB.TVH
4308BB.TVH bearings ( 40 mm x 90 mm x 33 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 4308BB.TVH 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.
