352940 / 2097940 Double Row Tapered Roller Bearing 200×280×105 mm | Heavy-Duty Industrial Bearing

352940 / 2097940 Double Row Tapered Roller Bearing — 200×280×105 mm

The 352940 bearing (also referenced as 2097940) is a double row tapered roller bearing with an inner diameter of 200 mm, outer diameter of 280 mm and width of 105 mm. At a weight of 18.8 kg, this is a large-format, heavy-duty bearing engineered for the most demanding industrial operating environments.

Double row tapered roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks and vibrations. The double-row configuration provides greater combined radial and bidirectional axial load capacity, improved shaft rigidity and better resistance to misalignment compared to single-row designs — making the 352940 a reliable choice for critical positions in heavy industrial equipment.

Nexans Bearing manufactures and exports industrial bearings from Liaocheng, Shandong, China. Since 1997, we have supplied B2B customers in more than 50 countries with bearing solutions for industrial, mining, metallurgical and heavy equipment applications. We support standard replacement orders, OEM production programs and customized private-label supply.

352940 Bearing Cross Reference

Different bearing catalogs and regional standards may use either designation. When sourcing this bearing, providing both references helps ensure correct product matching. Nexans Bearing recommends confirming dimensions and original markings regardless of the designation used.

Why Double Row Tapered Roller Bearings Are Specified for Heavy Industrial Applications

Double row tapered roller bearings are engineered to handle combined high radial and bidirectional axial loads simultaneously. Compared to single-row tapered roller bearings, the double-row configuration provides greater load capacity, improved rigidity and better resistance to misalignment — all critical requirements in heavy industrial environments.

Key performance advantages of double row tapered roller bearings include:

• High combined load capacity — handles both radial and axial forces in both directions simultaneously

• Superior shaft rigidity — two rows of rollers provide greater support and reduced deflection under load

• Misalignment tolerance — designed to accommodate shaft and housing misalignment under operating conditions

• Shock and vibration resistance — robust construction for equipment subject to impact and dynamic loads

• Contamination resistance — suitable for dusty, wet and heavily contaminated industrial environments

• Compact load envelope — higher load capacity within a given bearing envelope compared to equivalent single-row arrangements

These characteristics make the 352940 bearing particularly well suited to applications in rolling mills, mining equipment, hoisting machinery and heavy gearboxes, where bearing failure results in significant unplanned downtime and high maintenance costs.

Typical Applications

The 352940 / 2097940 double row tapered roller bearing is used across a range of heavy industrial sectors:

• Rolling mills — roll neck positions in hot and cold rolling mills, where high radial loads and bidirectional axial forces are generated continuously during the rolling process

• Mining machinery — crushers, conveyors, vibrating screens and tunnelling equipment operating under high loads and severe contamination

• Hoisting equipment — cranes, winches, hoists and lifting systems requiring reliable load support under dynamic and shock conditions

• Industrial gearboxes — heavy-duty reducers and power transmission systems in steel plants, cement works and mining operations

• Construction and earthmoving equipment — excavators, road headers and heavy construction machinery

• Metallurgical and processing equipment — continuous casting machines, heavy processing lines and steel plant auxiliary equipment

Material and Precision Grade Options

Bearing Steel Material

The 352940 bearing is manufactured from 52100 chrome steel, the internationally recognized standard bearing steel grade for high-load industrial rolling bearings. This material is referenced under equivalent national designations:

Precision Grades

Nexans Bearing can supply the 352940 bearing in multiple precision grades to match specific application requirements:

For standard heavy industrial applications, P0 / ABEC 1 is the normal precision grade. Higher precision grades (P5/P4 or ABEC 5/7) are recommended for applications requiring tighter dimensional tolerances, lower vibration or higher rotational accuracy.

Internal Clearance Options

Clearance selection should be based on operating temperature, shaft and housing fit, load conditions and rotational speed. For most heavy industrial applications, C3 is commonly specified where significant temperature rise is expected during operation.
