Spherical roller bearings
Spherical Roller Bearings are the most suitable option for applications that need shock-resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings’ alignment.
Due to the curved outer ring, Spherical Bearings come with self-aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in a harsh environment with a lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.
In rolling-element bearings (also called “antifriction bearings”), rolling elements such as balls or rollers interposed between the housing and the shaft produce rolling motion instead of sliding motion.
Where long relubrication intervals are desirable oil lubrication is recommended and specially designed Plummer block housings can be used. These have adequate space for an oil reservoir and have been developed mainly for high-speed fans. They are equipped with effective labyrinth seals to eliminate oil losses.
Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction.
They are also extremely resistant to shock loads and their self-aligning feature allows full capacity loading despite shaft deflection.
Also, the head shaft on a heavily loaded belt conveyor might deflect, or the support structure could also move slightly under load, increasing potential misalignment at the bearing. Spherical roller bearings are designed to rotate while constantly accommodating this “wobble” and yet carry full system load.
Standard Spherical Roller Bearings are produced with straight bores; however, tapered bores are available upon request and may be mounted directly on tapered shafts. Pressed steel and machined brass cages are typically used.
Constructionally, the bearings are self-aligning and are consequently insensitive to changes in the alignment of the shaft relative to the housing. They also have the ability to take off shaft bends to a certain extent.
Spherical roller bearings typically consist of an inner ring with two raceways inclined at an angle to the bearing axis, an outer ring with a common spherical raceway, spherical rollers, cages and in certain designs also internal guide rings or center rings.
Spherical Roller Bearings are commonly used in agricultural machines such as combined harvesting machine, air-blower, paper-machine, textile machine, woodworking machinery, overhead crane moving wheel and driving shaft as well as a large number of non-agricultural applications.
Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in the inner ring to support rotating shaft.
Amazingly the quality and alignment of raceways, cages, and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.
Cages like other bearings is available in this bearing to ensure the proper placing and holding of the rolling elements and preventing them from bumping against each other. The cages are normally separate for each row of the rolling element.
Spherical roller bearings are usually designed with two rows of rollers tilted at opposite angles to resist thrust load in either direction. Thrust loads are common when deflections and misalignments are sufficient to require a spherical roller bearing.
The design of these bearings means that they are naturally self-aligning and can handle very heavy radial and axial loads at moderate speeds. The internal design of these bearings is not standardized by ISO, so it varies between different manufacturers and different series.
Large paper machines may use as many as 3000 bearings, the majority of which are spherical roller bearings. Spherical roller bearings are able to support substantial axial and radial load combinations of the rolls and cylinders used.
These Bearings are manufactured with several kinds of material based on the application and working environment. Chrome steel is one of the most popular materials used in the production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications.
One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.
Spherical roller bearings can be found in a variety of applications including gearboxes, wind turbines, and pumps. They are most commonly made from chrome steel with cages made from brass, machined steel, sheet steel or polyamide.
For the special situation with only extremely high thrust load such as a rock crusher, you can use a spherical thrust bearing. It consists of one row of rollers positioned between special bearing races so that high axial shaft load can be transmitted through the bearing to the mounting structure and yet accommodate the types of misalignment described previously.
