NKE NU 2309 E TVP3 Single Row Cylindrical Roller Bearing 45x100x36 mm

AI Overview

The NKE NU 2309 E TVP3 is a single row cylindrical roller bearing designed to support high radial loads in industrial machinery and mechanical equipment. Featuring a 45 mm bore, 100 mm outside diameter and 36 mm width, this bearing uses the NU design with two flanges on the outer ring and no flanges on the inner ring, allowing axial displacement between the shaft and housing. The TVP3 designation identifies a glass fibre reinforced polyamide cage.

Weight: Approximately 1.3 kg

Product Description

The NKE NU 2309 E TVP3 is a precision single row cylindrical roller bearing developed for applications requiring high radial load capacity and reliable operation. Compared with ball bearings of similar dimensions, cylindrical roller bearings provide greater radial load capability because the rollers create a line contact with the raceways instead of point contact.

The NU design incorporates two integral flanges on the outer ring, while the inner ring has no flanges. This arrangement allows axial displacement between the shaft and housing, making the bearing suitable for applications where thermal expansion or shaft elongation must be accommodated without introducing additional internal stresses.

The bearing features a TVP3 cage manufactured from glass fibre reinforced polyamide. This cage accurately guides the cylindrical rollers, maintains proper spacing between rolling elements and contributes to smooth operation under normal operating conditions. The open bearing design allows lubrication to be selected according to the machine manufacturer's maintenance schedule and application requirements.

With standardized dimensions of 45x100x36 mm, the NU 2309 E TVP3 is easily identified during maintenance, repair and spare parts management. The internationally recognized designation simplifies bearing selection for OEM equipment, industrial maintenance departments and MRO operations.

This bearing is widely used in industrial machinery, power transmission systems, production equipment, industrial automation and mechanical engineering applications where high radial load capacity and axial displacement capability are required.
