Self-Aligning Ball B. FAG 2207 -K-2RS-TVH-C3

The FAG 2207 -K-2RS-TVH-C3 self-aligning ball bearing (35x72x23 mm) compensates for misalignment during operation and protects against contamination thanks to 2RS seals on both sides.

The FAG self-aligning ball bearing 2207 -K-2RS-TVH-C3 is a double-row roller bearing made from standard bearing steel (100Cr6) with a 35 mm bore, 72 mm outer diameter and 23 mm width. Thanks to the hollow-spherical outer ring raceway, this bearing compensates for misalignment between the inner and outer rings. Fitted with seals that make contact on both sides, it keeps out dust and dirt particles. The integrated polyamide cage ensures smooth running within a temperature range of -30 to +100 degrees Celsius.

What is the 2207 -K-2RS-TVH-C3 self-aligning ball bearing suitable for?

This double-row self-aligning bearing is used wherever shaft deflection or misalignment between the housing seats occurs. Thanks to the movable row of balls, the design automatically compensates for both static and dynamic angular misalignment without noticeably increasing friction. Thanks to the 2RS seals, the component is particularly suitable for environments exposed to dust or moisture. Specialists frequently use this bearing arrangement in shaft lines with long support spans, as well as in housings with alignment deviations resulting from the manufacturing process.

What are the advantages of the tapered bore and the C3 clearance?

The version with the suffix ‘K’ features a tapered internal bore with a ratio of 1:12. This enables secure mounting on cylindrical shafts using a clamping or withdrawal sleeve. As the inner ring expands when pressed onto the taper, the bearing clearance is reduced. This is where the extended radial clearance C3 comes into play: it specifically compensates for the reduction in clearance caused by installation, as well as thermal expansion during operation between –30 and +100 degrees, to prevent the rolling elements from seizing.
