Self-Aligning Ball B. FAG 2309 -TVH
The 2309-TVH self-aligning ball bearing reliably compensates for misalignment and shaft deflection with a shaft diameter of 45 mm and an outer diameter of 100 mm.
The 2309-TVH self-aligning ball bearing from FAG Rolling Bearings is a double-row bearing made from standard rolling bearing steel (100Cr6). Thanks to the continuous hollow-spherical raceway in the outer ring, the two rows of balls can swivel flexibly out of the centre position as required. The design is suitable for rotating shafts subject to misalignment or elastic deflection. With standard radial clearance and tolerance class P0/PN (ABEC 1), this open bearing meets standard precision requirements.
In which installation situations does the 2309-TVH self-aligning ball bearing prove its worth?
The double-row bearing compensates for geometric misalignments caused by offset or elastic shaft deflection. In the case of angular misalignments that would place excessive loads on rigid ball bearings, the spherical outer ring raceway allows for unhindered deflection. The open component requires an external housing seal and is lubricated directly with lubricating oil or grease.
What are the characteristics of the polyamide cage in the 2309 -TVH self-aligning ball bearing?
The suffix ‘TVH’ indicates a polyamide cage. This cage material reduces the mass of the moving components and promotes low-vibration, low-noise operation of the ball rows. The permissible temperature range is from –30 to +120 degrees Celsius. The ambient temperature should remain within this range during continuous operation in order to maintain the material’s thermal stability.
What are the key design features of the 2309-TVH self-aligning ball bearing?
This rolling bearing is characterised by two rows of balls on a shared hollow-spherical outer ring raceway. This geometry allows the inner ring, together with the rolling elements, to pivot freely about the centre point. This enables angular misalignment between the housing and the shaft to be automatically compensated for during operation without impeding the rotational movement.
What are the dimensions of the roller bearing?
Designed for shafts with a diameter of 45 mm, the bearing has a cylindrical bore. The outer diameter is 100 mm and the width is 36 mm. These dimensions define the installation space required within the housing and on the shaft for the open version.
What does the suffix ‘TVH’ mean in the case of FAG roller bearings?
The designation TVH refers to a polyamide cage. This material is characterised by its low weight, dampens operating noise and provides stable guidance for the two rows of balls. It is suitable for use with standard greases and mineral oil-based lubricating oils.
What is the temperature range for which the 2309-TVH self-aligning ball bearing is designed?
The specified operating temperature range is between –30 and +120 degrees Celsius. The integrated polyamide cage determines the upper temperature limit. Within these limits, the material retains its mechanical guidance properties and dimensional stability.
What type of seal does this bearing design have?
As an open roller bearing, this design has no integrated seals. Protection against dust and moisture is provided by the surrounding housing as a design feature. The open design facilitates relubrication and allows oil or grease to be applied from the outside.
What are the bearing clearance and tolerance class?
The bearing is manufactured with standard radial bearing clearance. Its dimensional and running accuracy complies with tolerance class P0/PN, which corresponds internationally to the ABEC 1 rating. These values define the guidance behaviour and the radial bearing clearance under normal installation conditions.
