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. Versatile Applications Across Industries

Series 33000-Single Row Tapered Roller Bearings exhibit a remarkable versatility that transcends industry boundaries, making them indispensable components in a myriad of applications. Their robust construction and ability to withstand high radial and axial loads render them suitable for various industries, including automotive, aerospace, mining, and construction. In the automotive sector, these bearings find extensive use in wheel hubs, transmission systems, and differential assemblies. Their ability to accommodate both radial and axial forces makes them ideal for supporting vehicle weight and transmitting torque, ensuring smooth and reliable operation on the road. Their compact design and high load-carrying capacity contribute to improved fuel efficiency and vehicle performance. In aerospace applications, where precision, reliability, and weight considerations are paramount, Series 33000-Single Row Tapered Roller Bearings play a critical role in aircraft landing gear systems, engine components, and flight control mechanisms. Their ability to operate under extreme temperatures and dynamic conditions makes them well-suited for the demanding requirements of aviation. In the mining and construction industries, where heavy-duty equipment operates in harsh environments, these bearings excel in supporting conveyor systems, crushers, and earthmoving machinery. Their rugged construction and resistance to contamination ensure uninterrupted operation even in dusty, abrasive, or corrosive conditions, contributing to increased productivity and reduced downtime. Series 33000-Single Row Tapered Roller Bearings are integral components in industrial machinery, such as machine tools, paper mills, and textile machines, where precise motion control and high reliability are essential. Their versatility extends to renewable energy applications, including wind turbines and solar tracking systems, where they contribute to the efficient conversion of renewable resources into electricity.

2. Maintenance and Service Considerations

While Series 33000-Single Row Tapered Roller Bearings are renowned for their durability and reliability, proper maintenance is imperative to ensure optimal performance and longevity. A proactive approach to maintenance not only minimizes downtime but also extends the service life of these critical components. Regular inspection is the cornerstone of effective maintenance practices. Visual examination of the bearings for signs of wear, corrosion, or damage allows early detection of potential issues, enabling timely corrective action to be taken. Monitoring operating temperatures and vibration levels can provide valuable insights into the health of the bearings and the overall condition of the machinery. Lubrication plays a pivotal role in the performance of tapered roller bearings. Adhering to recommended lubrication intervals and using the appropriate lubricant is essential for minimizing friction, reducing wear, and preventing premature failure. Whether utilizing grease or oil lubrication systems, ensuring adequate lubricant levels and proper distribution is paramount for maximizing bearing life and performance. In addition to regular maintenance tasks, periodic bearing replacement may be necessary, particularly in high-load or high-speed applications. Training maintenance personnel in proper handling, installation, and maintenance procedures is essential for ensuring the effectiveness of maintenance programs. By equipping personnel with the necessary knowledge and skills, organizations can mitigate the risk of improper handling or maintenance practices leading to premature bearing failure.
