INA SL181864-E-C3 320x400x38 full complement cylindrical roller bearing

Main Description

The INA SL181864-E-C3 320x400x38 is a high performance full complement cylindrical roller bearing designed for industrial applications requiring extremely high radial load capacity, excellent rigidity, and stable operation under intensive dynamic loading conditions.

This model belongs to the Cylindrical Roller Bearings category commonly used in heavy industrial gearboxes, steel industry equipment, power transmission systems, production machinery, industrial drive assemblies, and applications requiring exceptional operational durability. The full complement roller construction without a cage allows a greater number of rollers, significantly increasing radial load capacity and resistance to heavy operating loads.

The 320x400x38 dimensions make this bearing suitable for large mechanical systems operating under demanding industrial conditions. The E designation indicates a reinforced bearing design optimized for increased load carrying performance, while the C3 internal clearance ensures stable operation at elevated temperatures and higher rotational speeds.

INA is recognized worldwide as one of the leading manufacturers of industrial bearings used in advanced heavy industry and high performance drive systems.
