Self-Aligning Ball B. FAG 11505 -TVH

The FAG 11505-TVH double-row self-aligning ball bearing, with a polyamide cage and dimensions of 25 × 52 × 15 mm, compensates for misalignment and shaft deflection during operation.

The double-row self-aligning ball bearing 11505 -TVH absorbs radial forces and accommodates misalignment between the inner and outer rings. A common spherical raceway in the outer ring enables the angular movement required to compensate for dynamic misalignment during operation. FAG manufactures this model from through-hardened standard roller bearing steel 100Cr6 with a cylindrical bore and standard radial clearance. Thanks to its manufacture to standard tolerance P0 or ABEC 1, the bearing complies with the defined specifications for rotating shafts in mechanical engineering.

What is the 11505-TVH self-aligning ball bearing suitable for?

Design engineers select the 11505 -TVH self-aligning ball bearing for rotating shafts where misalignment between the bearing seats or deflection under load may occur. The double-row design guides the rolling elements evenly and is designed for assemblies subject to predominantly radial loads and low axial forces. Compared with rigid rolling bearings, the spherical raceway prevents edge pressure on the rolling elements when the shaft and housing tilt relative to one another. This ensures smooth concentricity even in the event of operational misalignment.

What are the characteristics of the TVH polyamide cage?

The suffix ‘TVH’ denotes a solid polyamide cage, which is lightweight and has elastic material properties. This cage design dampens operational vibrations, reduces running noise and keeps inertia low at varying speeds. The permissible temperature range of the rolling bearing extends from -30 to +120 degrees Celsius. As an open design without integrated seals, the bearing requires external sealing of the housing as well as regular lubrication with a suitable grease or lubricating oil.
