Self-Aligning Ball B. FAG 2209 -2RS-TVH
The FAG 2209 -2RS-TVH self-aligning ball bearing features compact dimensions of 45x85x23 mm, protection on both sides via 2RS seals, and compensates for misalignment during operation.
The 2209 -2RS-TVH self-aligning ball bearing is a double-row rolling bearing with a common hollow-spherical outer ring raceway. Thanks to this design, the bearing compensates for shaft misalignment as well as misalignment between the inner and outer rings. Manufactured from standard roller bearing steel 100Cr6 and fitted with a polyamide cage, this version is suitable for a wide range of industrial applications. With key dimensions of a 45 mm bore, 85 mm outer diameter and 23 mm width, this FAG product complies with the standard tolerance class P0/PN (ABEC 1).
What is the 2209-2RS-TVH self-aligning ball bearing suitable for?
Design engineers and maintenance technicians use this double-row bearing primarily in situations where deflection of long shafts or assembly inaccuracies may occur. The oscillating movement in the outer ring compensates for angular misalignment during operation without unnecessarily increasing friction. Typical applications include shaft mountings prone to deflection, designs with misalignment, and dusty operating environments. The seal, which contacts the shaft on both sides, protects the bearing assembly from particles, whilst the standard radial clearance ensures stable running characteristics.
What are the functions of the seal and the polyamide cage in the 2209-2RS-TVH?
The double-sided sliding seal (2RS) keeps out dirt particles and moisture and helps to retain the grease within the bearing chamber. In combination with the lightweight polyamide cage (TVH), the bearing operates with low vibration and minimal running noise. When designing the application, the permissible temperature range of -30 to +100 degrees Celsius must be observed; this is determined by the cage material and the seal material. When fitting with a cylindrical inner ring seat, ensure that the force is applied correctly and exclusively to the ring that is to be fitted tightly.
What are the dimensions of the 2209 -2RS-TVH self-aligning ball bearing?
This double-row roller bearing has a cylindrical bore of 45 mm, an outer diameter of 85 mm and a total width of 23 mm. Thanks to these standardised key dimensions and the tolerance class P0/PN (ABEC 1), the component can be fitted precisely into corresponding housing bores and onto suitable shaft seats.
What does the suffix 2RS mean for this bearing?
The abbreviation 2RS denotes a sliding contact seal fitted on both sides. These sealing lips make direct contact with the inner ring, keeping out ambient dirt and moisture and helping to retain the grease. This ensures that the bearing remains protected under normal industrial operating conditions.
What are the features of the TVH cage?
The suffix TVH indicates a polyamide cage. This thermoplastic cage is characterised by its low weight, elastic damping properties and quiet operation. The material reduces inertial forces during acceleration and guides the two rows of balls evenly along their paths.
Within what temperature range can the bearing be operated?
The permissible operating temperature range for this self-aligning ball bearing is between -30 and +100 degrees Celsius. This limit is primarily due to the thermal properties of the material used in the sealing lips and the polyamide cage. For applications with continuous operating temperatures beyond these values, variants with a sheet steel or brass cage are recommended.
What is the radial clearance of the 2209 self-aligning ball bearing?
The bearing has a standard radial clearance (CN), which is not specified separately in the abbreviated designation. This standard bearing clearance is designed for common fit selections and normal operating temperatures, under which the inner ring expands radially only within the intended limits due to the interference fit.
How does a self-aligning ball bearing compensate for misalignment?
The outer ring of the bearing has a continuous, hollow spherical inner raceway in which the two rows of balls can move freely together with the inner ring. As a result, in the event of shaft deflection or misalignment, the bearing automatically compensates within structural limits, thereby preventing edge loading on the rolling elements.
