Self-Aligning Ball B. FAG 1309 -TVH
The 1309-TVH double-row self-aligning ball bearing, with a 45 mm bore and a polyamide cage, reliably compensates for misalignment caused by dynamic shaft deflection.
The 1309-TVH self-aligning ball bearing from FAG Rolling Bearings is a double-row rolling bearing made from standard bearing steel (100Cr6) with a cylindrical inner ring bore. Thanks to the shared hollow-spherical raceway in the outer ring, the two rows of balls pivot continuously. This automatically compensates for misalignment between the inner and outer rings. Designed as an open bearing, this component can be flexibly integrated into existing lubrication circuits.
What is the 1309-TVH self-aligning ball bearing suitable for?
Design engineers and maintenance personnel primarily select this self-aligning bearing where shaft deflection or misalignment between bearing housings occurs. Typical applications are found in general mechanical engineering in designs with larger spans. The component primarily absorbs radial loads, but due to its design, it can also withstand axial forces in both directions. Thanks to its standard tolerance in class P0/PN (corresponding to ABEC 1), the bearing is suitable for standardised fits in industrial applications.
What are the advantages of the polyamide cage design?
The suffix ‘TVH’ denotes the integrated solid polyamide cage, which guides the balls precisely. Compared with heavy metal cages, this material reduces the moving mass within the bearing, promoting smooth and low-vibration operation. The permissible temperature range is from -30 to +120 degrees Celsius. As the bearing is of an open design, the installation point requires external sealing as well as suitable grease or oil lubrication, tailored to the standard radial bearing clearance.
What are the dimensions of the 1309-TVH self-aligning ball bearing?
This double-row roller bearing has an inner bore of 45 mm for mounting on the shaft. The outer diameter is 100 mm with a standardised width of 25 mm. The inner ring is manufactured in a standard cylindrical design, allowing the bearing to be fitted directly onto a suitable shaft.
How does the self-aligning bearing compensate for misalignment?
The internal contour of the outer ring forms a common spherical raceway for both rows of balls. This geometry allows the assembly comprising the inner ring, cage and balls to align freely within the outer ring. The bearing thus compensates for manufacturing-related misalignments in the bearing housings or elastic deflection of long shafts without the need for additional radial preload.
What does the suffix ‘TVH’ mean for this bearing?
The suffix ‘TVH’ denotes a solid cage made of polyamide. This type of cage offers good sliding properties, dampens running noise and keeps the rolling bearing’s own weight low. The material is designed for operating temperatures between -30 and +120 degrees Celsius.
What is the clearance in the 1309-TVH self-aligning ball bearing?
The component is manufactured with a standard radial bearing clearance. This standard clearance range is intended for typical industrial fit combinations and moderate operating temperatures. After being pressed onto the shaft and housing, a defined residual clearance remains, which facilitates the free rolling of the rolling elements.
Does the open bearing need to be lubricated before use?
Yes, as this is an open design without integrated sealing washers, the bearing is not filled at the factory. Suitable lubrication with roller bearing grease or oil is required for continuous operation. In addition, the surrounding bearing housing must be protected against the ingress of dirt using appropriate sealing elements.
What material are the rings and balls made of?
The bearing rings and rolling elements are made from standard roller bearing steel 100Cr6. This material is characterised by high compressive strength, wear resistance and dimensional stability under load. In combination with the more elastic polyamide cage, this results in a robust machine component for mechanical applications.
