Welcome to Linqing Xinshengdi Bearing Co., Ltd.
45244 Double Row Tapered Roller Bearing
45244 is a double row tapered roller bearing designed for heavy-duty applications requiring high radial load capacity and support for axial loads in both directions. Unlike a standard single-row tapered roller bearing, this design incorporates two rows of tapered rollers and an integrated inner ring assembly.
With a 220 mm bore diameter, 340 mm outside diameter and 90 mm overall width, the 45244 bearing is suitable for large industrial machinery, heavy-duty transmissions, gearboxes and other demanding rotating equipment. The integrated inner ring design provides a compact bearing arrangement and is suitable for applications where installation space and load support are important considerations.

Double Row Tapered Roller Bearing Design
The 45244 bearing uses two rows of tapered rollers to provide greater load support than a comparable single-row tapered roller bearing arrangement. Its integrated inner ring construction combines the inner-ring components into one assembly, which helps simplify bearing installation and provides a compact configuration for heavy-duty machinery.
Double row tapered roller bearings are commonly selected when equipment requires support for substantial radial loads together with axial loads. The actual load capacity, operating speed and service life depend on the complete bearing arrangement, operating conditions, lubrication, mounting accuracy and application requirements.
Applications
45244 double row tapered roller bearings can be used in a variety of heavy-duty industrial applications, including:
Heavy industrial gearboxes
Industrial transmissions
Large mechanical drive systems
Heavy machinery
Mining and material handling equipment
Steel and metal processing machinery
Large rotating equipment
Industrial replacement and maintenance applications
Advantages of the 45244 Bearing
The double-row configuration allows the 45244 to handle substantial loads within a single bearing position. Compared with using two separate single-row tapered roller bearings, an integrated double-row design can provide a more compact arrangement and simplify bearing selection and installation.
The integrated inner ring also makes the bearing convenient for applications where a complete inner-ring assembly is preferred. Before replacement, customers should always confirm the complete bearing designation and dimensional requirements of the original bearing.
Technical Selection Notes
When selecting a 45244 tapered roller bearing, customers should confirm the bore diameter, outside diameter, overall width, mounting arrangement, load direction, lubrication conditions and operating environment. For replacement projects, comparing the existing bearing designation and physical dimensions is recommended before ordering.
For applications with special load, speed or temperature requirements, DBS Bearing can review the application information and help confirm the appropriate bearing configuration.
