Deep Groove Ball Bearings FAG 6304 -TB
The FAG 6304-TB deep-groove ball bearing is an open rolling bearing with a fibre-reinforced cage, designed for shaft diameters of 20 mm and offering high speed capacity.
This single-row deep-groove ball bearing 6304-TB is designed for predominantly radial loads and also accommodates axial forces in both directions. Manufactured from standard roller bearing steel 100Cr6, this version has a bore of 20 mm, an outside diameter of 52 mm and a width of 15 mm. The bearing is manufactured by FAG and is designed as an open type without integrated sealing rings, allowing lubricants to reach the rolling elements unhindered during operation.
What is the 6304-TB deep groove ball bearing suitable for?
The bearing is primarily used in rotating systems where clean ambient conditions prevail or where a sealed machine housing provides protection against dirt. Typical applications include industrial drives and rotating assemblies with oil or external grease lubrication. Thanks to the combination of standard tolerance P0 and the cage guidance, the unit operates with low noise and low vibration even under demanding rotational movements.
What are the operational benefits of the hard-fabric cage?
The designation ‘TB’ indicates a hard-fabric cage, which has a lower weight than standard sheet-steel cages and effectively dampens vibrations. This material facilitates rapid acceleration and protects the rolling elements at high rotational speeds. The permissible temperature range extends from -20 to +120 degrees Celsius. This bearing is recommended for designers and maintenance engineers when smooth running and low friction losses are the primary considerations.
What are the dimensions of the 6304-TB deep-groove ball bearing?
The component has an internal bore of 20 mm, an external diameter of 52 mm and a width of 15 mm. These standardised dimensions of the 6304 series allow for a precise fit when mounted on suitable shafts and in cylindrical housing bores without a flange or circumferential groove.
What does the suffix ‘TB’ mean in relation to this ball bearing?
The abbreviation TB stands for a cage made of tough fabric. Cages of this design are characterised by a low specific weight and high dimensional stability. They significantly reduce running noise and are therefore well suited to applications involving high speeds.
What is the clearance of the 6304-TB deep-groove ball bearing?
This design features standard radial bearing clearance. This standard clearance between the rolling elements and raceways is matched to typical fit selections for shafts and housings. At conventional operating temperatures, the radial operating clearance therefore remains within the intended operating range.
How is the open roller bearing protected against contamination?
As the bearing is manufactured as an open type without its own sealing or cover rings, protection against dust and moisture must be provided by the housing design. Designers usually employ external shaft seals or labyrinth seals for this purpose, which also prevent the lubricant from leaking out.
What is the permissible temperature range for this bearing?
The manufacturer specifies an operating temperature range of -20 to +120 degrees Celsius for this version. Both the 100Cr6 rolling bearing steel and the hard-fabric cage retain their strength and dimensional stability within this range. The lubricant used should always be suitable for this temperature range.
In which tolerance class is the bearing manufactured?
The ball bearing complies with the standard tolerance P0 or PN, which is also referred to as ABEC 1 in international usage. This accuracy class fully meets the requirements of general drive technology and conventional mechanical engineering, and assumes that the bearing seats meet standard specifications.
