Power and Precision of Spherical Roller Bearings

Q: What is the main difference between a spherical roller bearing and a plain bearing?

The main difference lies in their design and function. A spherical roller bearing uses rolling elements (rollers) to minimize friction and handle radial and axial loads. They are also self-aligning. In contrast, a plain bearing relies on a sliding surface to support a shaft. While they are simpler in design and often used for lower speeds, they cannot compensate for misalignment and generally have higher friction than rolling element bearings.

Q: Are TFL's spherical roller bearings suitable for high-temperature applications?

Yes, TFL offers specialized high temperature bearings within our spherical roller bearing product line. These bearings are designed with materials and internal clearances that can withstand elevated temperatures without losing performance or durability. They are ideal for use in demanding environments like steel mills and kilns. Always specify the operating temperature range when selecting a bearing to ensure you get the right product for your needs.

Q: What are the benefits of using sealed spherical roller bearings over unsealed ones?

Sealed spherical roller bearings offer several advantages. The seals provide a protective barrier against contaminants like dust, dirt, and moisture, which can significantly extend the bearing's service life. They are also pre-lubricated for life, reducing the need for maintenance and re-greasing. While unsealed bearings are suitable for applications with a clean environment or where they can be regularly re-lubricated, sealed versions are the strong bearing choice for harsh or dirty conditions.

Spherical Roller Bearings are designed to handle heavy radial loads and moderate axial loads in both directions. With self-aligning capabilities, they are ideal for applications where shaft misalignment is common. Available in single row and double row configurations, they ensure low friction, long service life, and excellent performance in high-temperature or contaminated environments.

Double Row Spherical Roller Bearing

Designed for Alignment Challenges

Spherical Roller Bearings are uniquely designed to handle misalignment between the shaft and housing. This is achieved through their self-aligning raceways, which allow the inner ring to rotate freely within the outer ring without causing internal stress or premature failure. In many industrial applications, shaft deflections or mounting errors are common and can severely reduce bearing life if not properly addressed.

Compared to other types of bearings, spherical rollers maintain stable rotation, reduce frictional heat, and protect internal components even when the shaft bends under load. This makes them particularly suitable for vibrating screen machines, crushers, and mining equipment where dynamic misalignment and heavy vibration are constant challenges.

Whether installed in wind turbines with long shafts or in processing equipment exposed to shock loading, self-aligning spherical bearings minimize downtime and protect the system from wear. With their ability to compensate for angular errors, they extend both bearing life and machinery uptime.

Single & Double Row Configurations

Spherical Roller Bearings come in two primary configurations: single row and double row. While both feature self-aligning properties, they serve slightly different functions in industrial systems.

Single row spherical roller bearings are compact and suitable for applications where space constraints and moderate load conditions are present. Their simplicity makes them ideal for general machinery, where ease of mounting and cost-effectiveness are key.

Double row spherical roller bearings, on the other hand, offer greater radial and axial load-carrying capacity. With two symmetrical rows of rollers, they distribute load more evenly and operate with lower friction, even under extreme pressure. These bearings are highly recommended for heavy-duty equipment, such as crushers, gearboxes, and conveyors, where long service life and mechanical stability are essential.

Application Flexibility with Tapered and Straight Bore

TFL provides spherical roller bearings with both straight bore and tapered bore designs to meet varying mounting requirements. A plain bore bearing is often used in fixed installations with stable alignment, while tapered bore spherical roller bearings offer fast installation, especially when using adapter sleeves or withdrawal sleeves in tight spaces.

The tapered bore design also allows for adjusting internal clearance, which is crucial in applications with high thermal expansion or variable loading. This makes them ideal for rotary kilns, paper machines, and vibrating screen systems.

TFL’s design options provide custom-fit solutions to match mounting styles and performance goals. Whether you’re retrofitting existing equipment or developing new systems, our bearings give you the flexibility to optimize alignment, preload, and mounting security.
