Deep Groove Ball Bearings FAG 6305 -TB

The FAG 6305-TB deep-groove ball bearing, measuring 25x62x17 mm and featuring a hard-fibre cage, offers reliable running characteristics for predominantly radial loads.

The 6305-TB deep-groove ball bearing is a single-row rolling bearing of standard design, manufactured from conventional 100Cr6 bearing steel. It primarily absorbs radial forces, guides the shaft precisely and, at the same time, tolerates moderate axial forces in both directions. As an open bearing without integrated sealing washers, this FAG design allows for an unimpeded supply of lubricant within the system. The built-in hard-fibre cage ensures quiet, low-vibration operation of the rolling elements.

What is the 6305-TB deep groove ball bearing suitable for in operation?

Design engineers prefer to use the 6305-TB deep groove ball bearing in rotating industrial applications where a clean supply of lubricant is provided via the surrounding housing. Thanks to its solid hard-fabric cage, this variant performs well in drives with high speed requirements or dynamic accelerations. The absence of contact seals minimises rotational resistance, ensuring that friction and operating temperatures remain low during continuous operation. The component is suitable for a temperature range of -20 to +120 degrees.

What advantages does the hard-fibre cage offer in this FAG bearing?

The design suffix ‘TB’ refers to the guide cage made of textile-fibre-reinforced synthetic resin. Compared with standard sheet steel cages, the hard-fibre cage is characterised by its low weight and good damping properties. In combination with the standard radial bearing clearance and tolerance class P0/PN (corresponding to ABEC 1), the bearing is suitable for precise fits. When fitting, ensure there is adequate external housing sealing to prevent dirt particles from entering the open raceways.
