Single row spacer assembles 2TS-IM(indirecting mounting)LM12749 Bearing

Tapered roller bearings are a type of rolling-element bearing that feature a single row of rollers that are angled and converge towards a central point at the bearing's inner ring. These bearings are designed to handle both radial and thrust loads, making them highly versatile and efficient components that are commonly used in a wide range of industrial applications.

One popular version of the tapered roller bearing is the single row spacer assembly, also known as 2TS-IM (indirect mounting). This assembly consists of a single row of rollers that are separated by spacers, with the entire unit mounted indirectly to a shaft or housing using an outer race. The spacers help to maintain a constant clearance between the rollers, resulting in consistent performance over time.

The 2TS-IM assembly is particularly well-suited to applications that require high levels of durability and resistance to wear and tear. These bearings are able to handle heavy radial and thrust loads, and are also capable of withstanding high temperatures and harsh operating conditions. Typical applications for the 2TS-IM assembly include heavy equipment, construction machinery, and power transmission systems.
