Additional the standard metric single row taper roller bearings listed in the bearing table, DHK also produced single row taper roller bearings with flanges on outer rings (suffix R), only outer rings of taper roller bearing (prefix L), inner rings with the cage and rollers (prefix R) and other special taper roller bearings according to customer

Due to the single row taper roller bearings only can accommodate one direction axial force, these bearings are frequently used as pairs. Upon request, DHK can provide these bearings at Face- to-Face arrangement (suffix DF), Back-to-Back arrangement (suffix DB) or in tandem arrangement (suffix DT), as shown in the below sketch.
DHK taper roller bearings are fitted with pressed steel cages as standard. Because the cages of taper roller bearings usually protrude beyond the bearing faces, special care must be taken to follow the recommended abutment dimensions.

DHK single row taper roller bearings are produced to normal tolerance class (PN) as standard.

These bearings also may be produced with closer tolerance such as P6X on request.

Detail tolerance values are listed in the chapter of tolerance of metric taper roller bearings, page 14. The width tolerance of paired bearings is decided by the clearance and Ts.

The clearance of single row taper roller bearings is adjusted one bearing against another during mounting.

DHK taper roller bearing pairs arranged face-to- face (suffix DF) and back-to-back(suffix DB) are produced with internal clearance values, as listed in the table below. DHK can provide bearing pairs with special axial clearance upon request.

1. Dynamic and static load capabilities of series 32000 bearings

Dynamic load capacity is a critical parameter that defines the operational limits of tapered roller bearings under rotational conditions. The Series 32000-Single Row Tapered Roller Bearings excel in this aspect, boasting a dynamic load capacity of 1650 units. This metric signifies the maximum load that the bearing can endure while in motion, such as in rotating shafts or wheels. The robust dynamic load capacity of Series 32000 bearings ensures stable and reliable performance, even in high-speed applications where forces fluctuate rapidly. Engineers and designers can confidently specify these bearings for dynamic environments, knowing that they can withstand the rigors of continuous operation without compromising performance or safety. While dynamic load capacity gauges a bearing's ability to withstand forces during motion, static load capacity measures its resilience under stationary conditions. The Series 32000-Single Row Tapered Roller Bearings boast an impressive static load capacity of 3150 units, highlighting their resilience against sustained loads, such as those encountered in stationary machinery or structural components. This parameter is crucial for applications where loads remain constant or change gradually over time, ensuring the longevity and reliability of the bearing system. With a high static load capacity, Series 32000 bearings provide a solid foundation for industrial equipment, minimizing the risk of premature failure or deformation due to prolonged loading.

2. Applications Across Industries of series 32000 bearings

The versatility of Series 32000-Single Row Tapered Roller Bearings extends far beyond their technical specifications, finding diverse applications across a wide array of industries. In the automotive sector, these bearings are integral components in wheel hubs, transmissions, and differentials, where they facilitate smooth motion and efficient power transmission. In aerospace applications, they contribute to the performance and safety of aircraft landing gear systems, ensuring precision and reliability during takeoff and landing maneuvers. In heavy machinery and construction equipment, Series 32000 bearings play a pivotal role in supporting the immense loads encountered in earthmoving, mining, and material handling operations. Their ability to withstand both radial and axial loads makes them indispensable in conveyor systems, where they ensure uninterrupted material flow and operational efficiency. In renewable energy infrastructure such as wind turbines, these bearings enable the efficient conversion of wind energy into electricity, withstanding the dynamic forces generated by rotating turbine blades. Their reliability and durability contribute to the long-term performance and sustainability of renewable energy systems. Across these diverse industries and applications, Series 32000-Single Row Tapered Roller Bearings serve as critical components, driving efficiency, reliability, and safety. Their ability to endure harsh operating conditions while delivering consistent performance underscores their value as foundational elements in modern mechanical systems. As industries continue to evolve and innovate, the versatility and dependability of Series 32000 bearings remain unrivaled, shaping the future of engineering excellence.
