Product Features & Advantages
1. Single-row tapered roller bearings can support radial loads and axial loads in one direction simultaneously.
2. Axial forces generated under radial loading must be balanced; typically used in face-to-face or back-to-back pairs.
3. High rigidity, good wear resistance and long rolling fatigue life, suitable for heavy-duty and shock-loading conditions.
4. Precision-formed rollers and raceways ensure smooth rotation, low noise and stable running accuracy.
5. Single row tapered roller bearings are manufactured to commonly used metric bearing dimensions and designations, including the 30200, 30300, 32000 and 32200 series. Models such as 30205, 30206, 30207, 30208, 30209 and 30210 can be used as replacement options for bearings with the same standard designation from major brands such as SKF, FAG, NSK and Timken, subject to verification of dimensions, load ratings and application requirements. This makes them suitable for routine bearing replacement and maintenance in a wide range of industrial equipment.
Applications
● Automotive: wheels, differentials, transmissions, rear axles.
● Agricultural machinery: tractors, harvesters, gearboxes.
● Construction machinery: excavators, loaders, crushers.
● Metallurgical equipment, reducers, pumps, general machinery.

FAQ
Q1: Can single-row tapered roller bearings be used alone?
A1: They can bear axial force in one direction only. For bidirectional axial positioning, two or more bearings must be used in combination.
Q2: What do face-to-face and back-to-back mean?
A2: Face-to-face (DF) adapts to angular misalignment; back-to-back (DB) offers higher rigidity and moment load capacity.
Q3: What lubrication is recommended?
A3: Grease lubrication for general conditions; oil lubrication for high speed, high temperature or heavy load.
