TS Single Row Tapered Roller Bearings (Imperial)

TS (Single Row Tapered Roller Bearings) (Imperial) are essential components widely used in applications requiring the handling of both radial and axial loads. Known for their durability, low friction, and customizability, they are especially suited for heavy-duty environments such as automotive systems, industrial equipment, and aerospace assemblies. Our bearings are available in a broad size range and can be tailored to meet specific performance demands, including sealing options, precision grades, and material selection.

Design and Functionality of TS (Single Row Tapered Roller Bearings) (Imperial)

TS (Single Row Tapered Roller Bearings) (Imperial) are engineered to handle combined loads due to the intersection of raceway extensions at a single point on the bearing axis. This geometry ensures true rolling motion and reduced frictional torque during operation. The contact angle—typically between 10° and 30°—determines axial load capacity, which increases with a larger contact angle.

Materials

Chrome Steel: Offers high load capacity and low operational noise. Ideal for general applications.
440C Stainless Steel: Provides corrosion resistance with high-speed and high-load capabilities. Recommended for humid or chemically harsh environments.

Precision Grades (ABEC)

Available in ABEC-1 to ABEC-5. ABEC-3 is commonly used for standard applications, while ABEC-5 is ideal for precision systems requiring low noise, minimal runout, and extended service life.

Available Sizes

Bore diameters range from 7.937 mm to 1270.000 mm, covering a wide spectrum of industrial requirements.

Sealing Options

Open type (standard)
Rubber-sealed type (customized upon request)
Metal shielded type (customized upon request)

Performance Features

Low Friction

Optimized roller geometry and surface finishing promote a stable lubricant film, reducing both friction and heat generation. This contributes to better preload stability and quieter operation.

Extended Service Life

Logarithmic raceway profiles optimize load distribution and minimize stress peaks. This design enhances tolerance to misalignment and shaft deflection.

Enhanced Reliability

Surface treatments at contact areas facilitate dynamic pressure lubrication, improving long-term performance under demanding conditions.

Dimensional Precision

Rollers are produced to extremely tight tolerances, ensuring uniformity and consistent load distribution, which leads to lower vibration and improved preload control.

Preload and Rigidity

When used in pairs, these bearings can be adjusted to provide rigidity and accommodate complex loading situations.

Optimized Running-in

Initial running-in may result in higher temperatures due to friction. However, with correct installation and lubrication, friction and heat can be significantly reduced, ensuring stable operation.

Separable and Interchangeable Design

The inner and outer rings can be mounted separately. Interchangeability simplifies installation, disassembly, and maintenance.

Lubrication Options

We offer factory lubrication from a wide selection of greases or can use customer-specified lubricants. Our extensive lubrication experience ensures optimal performance for each application.

Temperature Resistance

Standard chrome steel variants operate continuously up to 120°C, and intermittently up to 150°C. With heat treatment and high-temperature grease, higher thresholds can be supported.

Common Applications

Automotive drive axles and gearboxes
Railway axle-boxes
Aerospace wheels
Machine tool spindles
Construction and mining equipment
Power plant coal transporters
Agricultural equipment such as raking machines and tensioners
Port machinery and gear reducers
