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. Design Features and Construction of Series 32200 bearings

The design and construction of Series 32200 bearings are a testament to precision engineering and advanced manufacturing techniques. Each component is crafted with meticulous attention to detail to ensure optimal functionality and durability. At the heart of Series 32200 bearings are the tapered raceways and rollers. These components are precisely machined to exacting tolerances, allowing for uniform load distribution across the bearing surfaces. As a result, stress concentrations are minimized, enhancing fatigue life and overall performance. The tapered rollers are carefully positioned within the bearing assembly to maintain proper contact angles with the raceways. This configuration not only facilitates smooth rotation but also ensures efficient load transfer, reducing the risk of premature wear or failure. The outer and inner rings of Series 32200 bearings are manufactured from high-quality materials, such as alloy steel, to withstand the rigors of heavy-duty applications. These rings undergo heat treatment processes to enhance hardness and toughness, ensuring prolonged service life and resistance to wear. Advanced sealing solutions are incorporated into the design to protect the bearing internals from contaminants and moisture. Seals or shields help maintain lubrication integrity, prolonging the intervals between maintenance cycles and enhancing overall reliability.

2. Load Bearing Capacity and Versatility

One of the standout features of Series 32200 bearings is their remarkable load-bearing capacity and versatility. Engineered to excel in handling both radial and axial loads, these bearings find application in a diverse range of industries and settings. In automotive systems, Series 32200 bearings play a critical role in supporting wheel hubs, providing the necessary strength and durability to withstand the forces encountered during vehicle operation. Whether navigating rough terrain or cruising at high speeds, these bearings deliver consistent performance, ensuring a smooth and reliable driving experience. In industrial machinery, Series 32200 bearings are employed in gearboxes, conveyor systems, and other heavy-duty applications where reliability and efficiency are paramount. Their ability to handle significant radial and axial loads makes them ideal for transmitting power and motion in demanding environments. From mining operations to manufacturing facilities, these bearings contribute to the seamless operation of critical machinery, enhancing productivity and minimizing downtime. Series 32200 bearings offer versatility in their application, thanks to their ability to accommodate both radial and axial loads simultaneously. This flexibility allows engineers and designers to optimize the performance of their systems while reducing the number of components required, simplifying assembly and maintenance processes.
