Thrust Ball Bearing

Thrust Ball Bearing

Thrust ball bearings are primarily designed to support axial loads. They feature a design capable of accommodating thrust loads at relatively high speeds and consist of washer-like raceways with ball rolling elements. Bearings with a spherical seating surface on the housing washer provide self-aligning capability, which helps reduce the effects of installation errors. Thrust ball bearings are not suitable for supporting radial loads and have relatively low limiting speeds.
Tapered Roller Bearing

Tapered Roller Bearing

Tapered roller bearings offer high load-carrying capacity and high operating speeds. They are typically equipped with pressed steel window-type cages, which promote effective lubrication. As separable bearings, the outer ring and inner assembly are interchangeable, facilitating installation and maintenance. They also feature low friction torque during operation. These bearings are designed to accommodate combined loads, i.e., simultaneously acting radial and axial loads, while maintaining high load capacity and high-speed performance.
Double Row Tapered Roller Bearing

Double Row Tapered Roller Bearing

In double row tapered roller bearings, either the outer ring or the inner ring is integrated as a single piece. The two inner rings or outer rings are arranged with their small end faces facing each other, with a spacer positioned in between. The internal clearance is adjusted by the thickness of the spacer, which can also be used to set the bearing preload. These bearings are capable of supporting heavy radial loads as well as axial loads in both directions, while providing high rigidity. They are typically used in gearboxes, lifting equipment, rolling mills, and mining machinery, such as tunnel boring machines.
Four Row Tapered Roller Bearing

Four Row Tapered Roller Bearing

Four row tapered roller bearings offer extremely high load-carrying capacity and are widely used in key components of heavy machinery. Their performance is generally similar to that of double row tapered roller bearings; however, they can support higher radial loads, while their limiting speed is lower. They are mainly used in rolling mills in the steel and non-ferrous metal industries and are suitable for operation under extremely harsh conditions.
Thrust Roller Bearing

Thrust Roller Bearing

Thrust roller bearings are primarily designed to support axial loads, while also accommodating combined radial loads; however, the radial load should not exceed 55% of the axial load. Compared with other thrust roller bearings, this type features a lower friction coefficient, higher operating speeds, and self-aligning capability. The rollers are long and large in diameter, with a high number of rollers, resulting in high load-carrying capacity. They are widely used in machine tool spindles, automotive transmission systems, construction machinery, the wind power industry, mining equipment, and industrial motors.
