NEWORLD Spherical Thrust Bearings

NEWORLD spherical thrust bearings are self-aligning and can accommodate heavy axial loads and simultaneously acting radial loads. They feature raceways with asymmetrical rollers and have a robust cage.

They are extremely easy to fit and can save costs in terms of procurement, maintenance and lubrication. They also help to reduce weight and increase the energy efficiency of your machine.

Self-aligning

The internal self-alignment of the rollers during operation compensates for mounting errors and shaft deflection, which reduces the load on bearing elements. The special roller profile also reduces edge stresses and frictional heat, which makes the spherical thrust bearing suitable for relatively high speeds.

The spherical thrust bearing is a non-separable bearing unit consisting of a shaft washer, an inner ring with a spherical raceway and a cage. The cage forms a continuous contact with the shaft washer and the outer ring to transfer axial loads without excessive radial clearance.

Double row angular contact ball bearings with a spherical outer ring raceway are self-aligning and can support axial loads in both directions as well as radial loads. They are used in applications such as intermediate propellor shafts and gearbox secondary output shafts.

High axial load capacity

Spherical thrust bearings can be used to support axial loads. They have a simple structure and high axial rigidity, which makes them ideal for applications that require high load capacity. They can be used in blowout preventer systems, for example.

Thrust spherical bearings have high axial load capacity and are more resistant to shock and heavy loads than other types of thrust bearings. They also have better geometrical accuracy and roughness than cylindrical roller bearings.

The internal self-alignment of spherical thrust bearings compensates for shaft deflection and housing distortions. This feature reduces friction and improves life expectancy.

High load capacity in radial direction

Unlike ball bearings, which must be preloaded, spherical thrust bearings can withstand very high loads without damage to the bearing. They can also withstand combined radial and axial loads, which is why they are seen in heavy equipment like large cranes and off-road vehicles. For higher speeds and load capacity, full complement designs use a cage to hold the balls, increasing the number of rollers that can fit between the raceways and thus the load-carrying capability.

igus offers several different types of spherical thrust bearings to meet your application needs. Contact our application engineers to determine potential savings for your specific application.

High speed capacity

Spherical roller thrust bearings are able to operate at high speeds due to their internal design, which creates a pumping action that moves oil from the small to large roller end face. This feature allows for higher speed limits than conventional thrust bearings, which are limited by the heat generated and load on the bearing.

Their low-friction design helps minimize wear on the shaft and bearing, resulting in superior operational performance over time. Additionally, their self-aligning properties reduce misalignment in the extruder system, ensuring stability and smooth rotation.

NEWORLD offers two types of spherical thrust bearings: the TT type, which has a flange on the housing washer (outer ring), and the E-type, which features a pressed cage. The TT and E-types are self-aligning and unaffected by mounting errors or shaft deflection.

Low friction

Unlike other types of bearings, spherical thrust bearings can handle both axial and simultaneous radial loads. They also have a lower friction rate, which allows them to operate at higher speeds. They can also withstand fluctuating load conditions, making them ideal for use in turbines. These bearings typically have a cage design, which holds the spherical rollers. The cages are made of stainless steel or other materials, and they separate the rollers from each other to prevent them from contacting and damaging each other.

They are also resistant to corrosion, which makes them a good choice for environments with moisture and other corrosive substances. Their low friction design helps reduce wear on the bearings and shaft, extending their life. This also leads to decreased maintenance requirements and increased machine efficiency.
