Product Description
The 7813 bearing is a single-row tapered roller bearing with an inner diameter of 65 mm, outer diameter of 110 mm and width of 30.35 mm. It is also referenced under the updated standard designation 33113X2. With a weight of approximately 1.10 kg, this bearing is designed to carry combined radial and unidirectional axial loads, making it suitable for demanding rotational applications in automotive and industrial equipment.
Tapered roller bearings in this size range are widely used in automotive wheel hubs, agricultural machinery, gearboxes and related drivetrain components. The 7813 designation is commonly used in markets that follow older national bearing standards, while 33113X2 is the more current cross-reference used in international catalogs.
Nexans Bearing manufactures and exports tapered roller bearings from Liaocheng, Shandong, China. Since 1997, we have supplied B2B customers in more than 50 countries with bearing solutions for automotive, industrial and agricultural applications. We support standard replacement orders, OEM production programs and customized private-label supply.

Different markets and catalogs may use either designation. When sourcing this bearing, providing both references helps ensure correct product matching. Nexans Bearing recommends confirming the bearing dimensions and original markings regardless of the designation used.
The 7813 tapered roller bearing is used across a range of automotive and industrial applications where combined radial and axial load capacity is required:
Automotive wheel hubs — passenger cars, light commercial vehicles
Agricultural machinery — combines, tractors, seeders and tillage equipment
Gearboxes and reducers — industrial and automotive drivetrain systems
Motors and pumps — general industrial rotating equipment
Fans and blowers — HVAC and industrial ventilation systems
Household and light industrial appliances
The final bearing selection should consider load magnitude, operating speed, lubrication method, shaft and housing fit, ambient temperature and contamination exposure.
Tapered roller bearings are designed to handle combined radial and unidirectional axial loads simultaneously. In wheel hub and drivetrain applications, this load combination is common because the bearing must support both the vehicle weight (radial load) and the lateral forces generated during cornering or gear engagement (axial load).
The internal geometry of a tapered roller bearing — with tapered rollers running between a tapered inner ring (cone) and outer ring (cup) — allows efficient load distribution across a larger contact area compared to ball bearings of similar size. This makes tapered roller bearings a practical choice for applications requiring durability under sustained combined loading.
Nexans Bearing operates from a 10,000 m² production facility in Liaocheng, Shandong, with dedicated bearing production lines for multiple bearing types, including tapered roller bearings. Factory-direct supply helps distributors and OEM buyers manage product specifications, control costs and build a more reliable supply chain.
Nexans Bearing conducts dimensional inspection in accordance with ISO 492 requirements and performs load-related testing with reference to ISO 281 principles before shipment. For tapered roller bearing orders, consistent dimensional accuracy is critical to correct installation and service performance.

The 7813 bearing is a single-row tapered roller bearing with dimensions of 65 mm bore, 110 mm outer diameter and 30.35 mm width. It carries combined radial and unidirectional axial loads and is used in automotive wheel hubs, agricultural machinery and gearbox applications. The updated cross-reference designation for this bearing is 33113X2.
7813 is the legacy bearing designation used in older national standards, while 33113X2 is the updated standard reference for the same bearing. Both designations refer to a tapered roller bearing with the same basic dimensions: 65 mm × 110 mm × 30.35 mm. When sourcing, providing both references helps ensure correct product identification.
