Overview and Design of TS (Single Row Tapered Roller Bearings) (Metric)

TS (Single Row Tapered Roller Bearings) (Metric) feature a tapered inner ring assembly and a separately mounted outer ring. The raceways are designed such that their extensions converge at a single point on the bearing axis, enabling true rolling motion. This architecture minimizes frictional torque and ensures high efficiency in handling combined loads—both radial and axial. As the contact angle (typically between 10° and 30°) increases, the bearing’s axial load capacity improves accordingly.

Material Options

Chrome Steel: The most commonly used material, valued for its high load capacity, low noise, and general reliability in standard conditions.
440C Stainless Steel: Offers excellent corrosion resistance and is ideal for high-speed, high-load, and high-moisture environments.

Precision Grades (ABEC)

Available in ABEC-1 through ABEC-5, these bearings support a variety of applications depending on required tolerances. ABEC-3 is suitable for general use, while ABEC-5 provides superior race finish and tighter runout control—ideal for precision assemblies where noise reduction and bearing longevity are priorities.

Sizes and Dimensions

Standard bore diameters range from 7.937 mm to 1270.000 mm, covering most industrial and engineering needs.

Sealing Configurations

Open Type: Most common configuration, suitable for applications with external lubrication.
Rubber Sealed: Offers protection from contaminants in dusty or wet environments (customizable).
Metal Shielded: Prevents large particles from entering while allowing heat dissipation (customizable).

Key Performance Features

Low Friction Operation

Optimized roller geometry and fine surface finishes help maintain a stable lubricant film. This reduces friction, wear, and heat generation—leading to quieter operation and better preload control.

Extended Service Life

Logarithmic raceway profiles distribute loads evenly and reduce stress concentrations, improving misalignment tolerance and shaft deflection resistance.

Reliable Performance

Advanced surface treatments on the roller and raceway enhance fluid film formation, boosting operational stability and reducing wear under dynamic conditions.

Dimensional Precision

Rollers are manufactured with exceptionally tight tolerances, ensuring consistent load distribution and minimizing vibration—key for precision applications.

Preload and Rigidity

When mounted in opposing pairs, these bearings can be preloaded to achieve high system rigidity and precise shaft positioning.

Running-in Efficiency

Bearings may exhibit higher friction during the initial running-in period. However, proper mounting and lubrication significantly reduce heat generation and wear, ensuring smoother long-term operation.

Separable and Interchangeable Design

Inner and outer rings are separable, simplifying installation, removal, and maintenance. Components of the same designation are fully interchangeable.

Lubrication Options

We offer factory lubrication using a vast selection of high-performance greases and oils. Custom lubrication using client-specified products is also available, backed by over two decades of lubrication engineering expertise.

High Temperature Resistance

Standard chrome steel bearings operate up to 120°C continuously and 150°C intermittently. For higher thermal loads, we offer customized solutions with specialized heat treatment and high-temperature lubricants.
