Self-Aligning Ball B. FAG 2208 -TVH

The FAG 2208-TVH self-aligning ball bearing, with dimensions of 40 × 80 × 23 mm and a hollow-spherical outer ring raceway, compensates for shaft deflection.

The double-row self-aligning ball bearing 2208-TVH is an open rolling bearing made from conventional standard rolling bearing steel (100Cr6). Thanks to the continuous, hollow-spherical raceway of the outer ring, the bearing self-aligns in the event of misalignment. As a result, this component compensates for static misalignment errors as well as dynamic shaft deflection during operation. The product is manufactured by FAG and complies with the specifications of tolerance class P0/PN or ABEC 1.

What is the 2208-TVH self-aligning ball bearing suitable for?

Designs featuring long shafts or split housings are prone to misalignment and elastic deflection during operation. It is precisely in such bearing arrangements that this component comes into its own. The two rows of balls absorb radial loads, whilst the bearing compensates for angular misalignment between the inner and outer rings. As this is an open design without sealing washers, the bearing must be incorporated into an external lubrication system using oil or grease.

What are the distinctive features of the TVH polyamide cage?

The suffix ‘TVH’ denotes a polyamide cage that guides the rolling elements and ensures quiet operation. This material reduces the cage’s weight and withstands loads within a temperature range of –30 to +120 degrees. Fitted with standard radial bearing clearance and a cylindrical bore, the inner ring can be mounted directly onto a 40 mm shaft. When designing the bearing, take into account the temperature range and the need for on-site sealing against contaminants.
