TIMKEN 795/792CD Double Row Inch Tapered Roller Bearing 4.75×8.125×4.25 Inches

The TIMKEN 795/792CD is a double row tapered roller bearing designed for heavy-duty applications where high radial and axial loads are prevalent. Manufactured by TIMKEN, a leading global supplier of bearings and power transmission products, this bearing offers superior performance, durability, and reliability, making it ideal for demanding industrial and automotive applications.

Design and Construction

The TIMKEN 795/792CD bearing features a double row configuration of tapered rollers, specifically designed to handle combined radial and axial loads. The bearing consists of two main parts: the inner ring assembly (cone) with the rollers and the outer ring (cup). The tapered rollers are positioned between these rings, aligned in such a way that they converge at a common point on the bearing axis. This unique geometry allows the bearing to efficiently manage loads from multiple directions, including heavy radial and axial loads.

The bearing dimensions are 4.75 inches (120.65 mm) in inner diameter, 8.125 inches (206.375 mm) in outer diameter, and 4.25 inches (107.95 mm) in width. These dimensions provide a substantial load capacity, making the TIMKEN 795/792CD suitable for applications where space constraints must be balanced with the need for high load handling.

Materials and Durability

Constructed from high-quality, case-hardened steel, the TIMKEN 795/792CD bearing exhibits excellent strength and resistance to wear and fatigue. The case-hardening process enhances the surface hardness of the bearing components while maintaining a tough, ductile core. This combination of surface hardness and core toughness provides superior resistance to shock loads and reduces the risk of spalling and pitting, which are common issues in bearings subjected to heavy and fluctuating loads.

The tapered roller design also ensures optimal contact between the rollers and raceways, distributing loads evenly and reducing stress concentrations. This results in smoother operation, reduced friction, and lower operating temperatures, which contribute to the bearing’s extended service life and reliability.

Performance Features

The double row configuration of the TIMKEN 795/792CD allows it to handle higher loads compared to single row tapered roller bearings. The bearing is capable of supporting significant axial loads in both directions, in addition to high radial loads. This makes it particularly effective in applications where the direction of axial load can vary, such as in gearboxes, heavy machinery, and wheel hubs.

One of the key performance features of the TIMKEN 795/792CD is its ability to maintain alignment under heavy loads. The bearing is designed to accommodate a certain degree of misalignment between the shaft and the housing, which is particularly useful in applications where perfect alignment cannot always be guaranteed. This helps to prevent premature bearing failure due to misalignment, further enhancing the reliability of the bearing in challenging operating conditions.

Applications

The TIMKEN 795/792CD is widely used in various industries, including automotive, industrial machinery, construction equipment, and mining. Common applications include use in gearboxes, differentials, wheel hubs, and other components where high load capacity and durability are critical. In the automotive sector, for example, these bearings are often found in heavy trucks and trailers, where they contribute to the reliable operation of axles and drivetrains.

In industrial applications, the bearing’s ability to handle heavy radial and axial loads, along with its resistance to wear and fatigue, makes it ideal for use in machinery that operates under harsh conditions, such as crushers, conveyors, and heavy-duty pumps.在

Maintenance and Longevity

The TIMKEN 795/792CD bearing is designed for long service life with minimal maintenance requirements. The use of high-quality materials and precision engineering results in a bearing that is resistant to common causes of bearing failure, such as wear, fatigue, and misalignment. Proper lubrication and routine inspection can further extend the bearing’s operational life, ensuring reliable performance over extended periods.

Conclusion

The TIMKEN 795/792CD double row inch tapered roller bearing is a robust and versatile component designed to meet the demands of high-load applications. Its double row design, high-quality materials, and precision engineering make it capable of handling heavy radial and axial loads with exceptional reliability. Whether used in automotive, industrial, or heavy machinery applications, the TIMKEN 795/792CD provides superior performance, durability, and longevity, reflecting TIMKEN’s commitment to quality and innovation in bearing technology.
