Self-Aligning Ball B. FAG 2206 -K-2RS-TVH-C3
The FAG 2206 -K-2RS-TVH-C3 self-aligning ball bearing compensates for misalignment, measures 30 x 62 x 20 mm and is protected against dirt by a 2RS seal.
The FAG 2206 -K-2RS-TVH-C3 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6). The hollow-spherical outer ring raceway automatically compensates for angular misalignment and shaft deflection during operation. Fitted with 2RS seals that seal on both sides, the design keeps out dust and moisture. With dimensions of a 30 mm bore, 62 mm outer diameter and 20 mm width, the component meets tolerance class P0/PN or ABEC 1. It is suitable for a temperature range of -30 to +100 degrees.
What is the 2206 -K-2RS-TVH-C3 self-aligning ball bearing suitable for?
This rolling bearing is suitable for designs where misalignment between the shaft and housing occurs or where elastic shaft deflection takes place. The hollow spherical raceway in the outer ring allows for the compensation of static and dynamic angular misalignments without obstructing the movement of the two rows of balls. Thanks to the seal that contacts the shaft on both sides, the bearing protects the inner rolling elements from ingress of dirt particles. This makes the design suitable for demanding industrial applications with harsh environmental conditions.
What do ‘tapered bore’ and ‘C3 clearance’ mean for this bearing?
The suffix ‘K’ denotes a tapered bore with a taper ratio of 1:12. This design facilitates mounting on tapered shaft seats or, with the aid of adapter sleeves, on cylindrical shafts. When pressed onto the tapered seat, the bearing clearance is measurably reduced. The design with a slightly increased radial clearance (C3) compensates for this press-fit effect, ensuring that a suitable operating clearance remains after installation. The integrated polyamide cage (TVH) guides the balls with low friction and is suitable for operating temperatures ranging from -30 to +100 degrees.
What are the dimensions of the 2206 -K-2RS-TVH-C3 self-aligning ball bearing?
The component has an internal diameter of 30 mm, an external diameter of 62 mm and a width of 20 mm. The manufacturing accuracy corresponds to tolerance class P0/PN or ABEC 1. Furthermore, the double-row version features a tapered bore with a taper ratio of 1:12.
How does angular misalignment compensation work in a self-aligning ball bearing?
The angular misalignment compensation is based on the continuous hollow-spherical raceway of the outer ring. Both rows of balls run in separate grooves in the inner ring and can tilt together with the inner ring within the outer ring. As a result, the bearing automatically compensates for misalignment, alignment errors and shaft deflection without any additional forced forces acting on the rolling elements.
What is the purpose of the tapered bore marked ‘K’?
The tapered bore with a 1:12 taper ratio enables a secure fit on tapered bearing seats or cylindrical shafts using a clamping or withdrawal sleeve. When the inner ring is pushed on axially, the bore narrows in a controlled manner, allowing you to determine the interference fit and the remaining bearing clearance during installation via the axial displacement.
Why does this bearing have a clearance rating of C3?
The C3 version has a slightly increased radial bearing clearance in its initial state. When a bearing with a tapered bore is fitted, the radial clearance is reduced as a result of the bearing being pressed onto the tapered seat. The increased initial clearance ensures that the bearing rotates freely after fitting and during operation-induced heating, and does not become seized.
What protection does the 2RS seal offer?
The abbreviation 2RS stands for seals fitted on both sides that provide a sliding seal. These sealing lips make contact with the inner ring and shield the interior of the bearing from dust, dirt and moisture. At the same time, the lubricant remains within the bearing, which minimises maintenance requirements within the permissible temperature range of -30 to +100 degrees.
What are the key features of the TVH polyamide cage?
The cage, designated TVH, is made of polyamide. This material is characterised by its low weight, elastic properties and favourable sliding characteristics in relation to the rolling elements. The polyamide cage operates quietly and is designed for continuous use within the specified temperature range of -30 to +100 degrees.
