Single Row Spherical Roller Bearings
TFL’s single row spherical roller bearings are engineered for demanding applications where space, vibration, and load capacity must be balanced. Featuring a single row of asymmetrical rollers and self-aligning geometry, these bearings resist misalignment and shaft deflection while maintaining smooth operation.
Self-Aligning Performance in a Compact Design
One of the key features of single row spherical roller bearings is their ability to accommodate shaft misalignment without sacrificing efficiency. The self-aligning function compensates for angular errors and mounting inaccuracies. Despite having only one row of rollers, the bearing maintains rigid radial support, making it ideal for installations where both space and alignment flexibility are limited.
Whether used in compact vibrating screens, belt conveyors, or industrial fans, TFL single row bearings ensure steady performance and reduce the risk of premature failure due to misalignment.
High Load Capacity with Minimal Friction
Though compact, single row spherical bearings are capable of handling heavy radial loads and moderate axial loads due to their robust roller geometry and deep raceway design. TFL’s manufacturing process ensures low-friction contact, reducing heat and energy loss in continuous operation.
This makes them particularly effective in gearboxes, pumps, and machinery running at high speeds, where load and heat must be controlled. The improved cage structure allows for better lubricant flow, extending bearing life and reducing downtime.

FREQUENTLY ASKED QUESTIONS
What is the main advantage of a single row spherical roller bearing?
The key advantage is its combination of compact size and high radial load capacity. It also offers self-aligning properties, which allow it to perform well even in the presence of shaft misalignment or housing deformation.
In what applications are single row spherical roller bearings commonly used?
These bearings are widely used in compact machinery, vibrating equipment, gearboxes, and fans. They're ideal when space is limited but reliable support is required.
How do I select the right clearance for my bearing?
Bearing clearance depends on the application’s operating temperature, load, and speed. TFL provides a bearing clearance chart to help select the right class (C2, CN, C3, etc.), or you can consult our technical team.
What is the difference between single and double row spherical roller bearings?
Single row bearings are more compact and suitable for moderate loads. Double row bearings handle higher loads and provide greater stability under axial forces but require more space.
