FAG Tapered Roller Bearing 55 mm Inside Diameter, 120 mm Outside Diameter, Steel Cage, Open End Type 31311-A

FAG 31311-A is a high-quality tapered roller bearing engineered for industrial use, featuring a 55 mm inside diameter and a 120 mm outside diameter. This bearing is constructed with a steel cage and an open end type design, providing durable and reliable performance under demanding conditions.

The 31.5 mm cone width enhances its ability to handle high radial loads, while accommodating significant axial forces on one side. With a static load rating of 139 kN and a dynamic load rating of 123 kN, this bearing can support combined loads efficiently, making it ideal for applications requiring precise axial guidance of the shaft and high running accuracy.

This tapered roller bearing is used where high axial rigidity is necessary and is designed for clearance-free or preload settings, often operated as a single bearing or adjusted against each other in pairs. It offers a compact, rigid, and economical bearing arrangement with robust load carrying capacity, more efficient than angular contact ball bearings where higher speeds are not essential.

The bearing’s design does not allow for misalignment compensation, thus it is perfect for rigid and precise bearing arrangements in industrial machinery such as manufacturing equipment, mechanical systems, and power transmission units.

With its rugged construction and proven reliability, the FAG 31311-A bearing is a preferred choice for industries requiring sustained heavy load handling, precision, and durability.

The bearing features a steel cage ensuring durability and strength. It has an open end type allowing for versatile applications. The cone width measures 31.5 mm, supporting robust axial and radial load carrying capability.

Static and dynamic load ratings are 139 kN and 123 kN respectively for reliable operation. The bearing supports precise axial guidance of shafts with high running accuracy. Designed for combined radial and axial loading with clearance-free or preload operation.

The compact, rigid design ensures high axial rigidity and load carrying capacity. The bearing does not compensate for misalignments, suitable for rigid assemblies. Ideal for demanding industrial applications such as manufacturing, machinery, and mechanical systems.
