The transmission of torque (effort) in almost any mechanical device, from wristwatches to heavy mobile equipment, involves the use of special devices, the number of types (names) of which has long exceeded thousands of units. Rolling bearings to varying degrees:
- Act as a support for a rotating shaft of a power plant or other mechanism that acts as a drive, a place where parts are connected.
- Transfers rotation to a part or device to perform specific structural tasks (for example, rotation of a wheel on a car hub).
In this case, for the simultaneous transmission of radial, axial or combined rotations, spherical bearings are used, which have a spherical shape of the sliding sliding surface. This type of product, despite all the efforts of manufacturers, introducing the most advanced technologies and innovative materials in their development, have the shortest operating life due to:
- With the design of the device - they do not have the usual rollers (balls) allowing to reduce the friction that occurs during rotation.
- The presence of radial and axial directions of rotation, as well as shock loads, leads to faster wear.
- High temperature parameters arising during operation due to intense friction have a negative effect on the metal structure.
This type of bearing is widely used in the design of complex agricultural machinery, including imported and domestic models of combines. Their maintenance (checking for the presence of lubrication and the absence of critical performance), as well as planned replacement should be carried out in accordance with the manufacturer's regulations.
Classification of spherical roller bearings
Official delivery of spherical roller bearings from enterprises that carry out their serial production is carried out in the so-called split format:
- Body (outer part).
- Working element (sleeve mounted on shaft).
Individual parts of each product are fixed together at the factory with wire and can be packed in a separate box. Classification implies, in addition to the presence in the technical description of all the dimensional parameters necessary for installation, also mandatory information about the design features of a particular model (grooves and holes for lubrication, slots or breaks). As well as the type of lubricant used.
Get acquainted with the catalog, in which each presented articulated bearing bearing is accompanied by detailed technical the product passport, drawn up at the manufacturer's plant, can be done using the official website of the Technakat company, which supplies them to the domestic market. For an individual consultation regarding the selection and purchase of the resource, the option of contacting the technical project manager is provided.
