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. Understanding Series 30200 Single Row Tapered Roller Bearings

Series 30200 Single Row Tapered Roller Bearings are engineered to accommodate both radial and axial loads by virtue of their tapered design. This configuration enables efficient distribution of forces along the bearing axis, allowing for smooth and reliable operation even under demanding conditions. The tapered geometry of these bearings ensures that the contact between the rolling elements (tapered rollers) and the races (inner and outer rings) occurs at a precise angle, facilitating optimal load distribution and minimizing friction. Within the Series 30200, the inner ring (cone) and outer ring (cup) are meticulously designed to ensure proper alignment and fit, essential for maintaining structural integrity and load-bearing capacity. The tapered rollers, positioned between the inner and outer rings, transmit forces between the two races while accommodating any misalignment or deflection, thus mitigating stress concentrations and reducing the likelihood of premature wear or failure. Series 30200 bearings are equipped with a cage assembly that retains and guides the tapered rollers, ensuring uniform spacing and alignment. This feature not only enhances the overall stability of the bearing but also reduces frictional losses, contributing to improved efficiency and reduced operating temperatures. The design of Series 30200 Single Row Tapered Roller Bearings embodies a harmonious balance between structural integrity, load-carrying capacity, and operational efficiency. By virtue of their tapered configuration and meticulous engineering, these bearings stand as reliable assets in various industrial applications, providing exceptional performance and longevity.

2. Design Features and Construction

The construction of Series 30200 Single Row Tapered Roller Bearings is testament to precision engineering and meticulous craftsmanship. Each component is carefully crafted and assembled to exacting standards, ensuring optimal performance and longevity in diverse operating environments. The inner and outer rings of Series 30200 bearings are forged from high-quality steel, selected for its exceptional strength, durability, and resistance to deformation. Through advanced manufacturing processes such as precision grinding and heat treatment, these rings are meticulously finished to precise dimensions and surface finishes, facilitating smooth and efficient operation. The tapered rollers, another critical component of Series 30200 bearings, are engineered to withstand high radial and axial loads while minimizing frictional losses. These rollers are precisely machined and heat-treated to enhance hardness and durability, ensuring reliable performance under varying operating conditions. Complementing the inner and outer rings and tapered rollers is the cage assembly, typically constructed from steel or synthetic materials. The cage serves to retain and guide the rollers, preventing contact and friction between adjacent elements while maintaining proper spacing and alignment. This feature not only enhances the overall stability of the bearing but also promotes smoother rotation and reduced wear over time.
