Bearings are an important link for transmitting the torque needed to perform useful work. They are used in the structural schemes of a wide variety of mechanisms and machines. As a result of exposure to significant loads, these units are subject to rapid operational wear and are replaced with analog products as needed. A special online reference guide and website will help with self-selection of the desired type.
What you need to know when choosing a bearing
Bearings are produced by various manufacturers and are classified according to the parameters set in the country. In addition to the Russian GOST, products labeled SKF (Sweden), Timken (USA), FAG (Germany), NSK and NTN (Japan), used in foreign-made machinery, are in high demand. To select the desired name through the directory, if there is no catalog number, you will need to specify the type:
- Radial and angular contact ball bearings.
- Spherical double-row roller bearings.
- Tapered roller bearings.
- Hinged.
- Additionally, the specifics of operation, the type of load and the direction of rotation are taken into account. The manufacturer specifies the maximum angular velocities for each item. Required sizes:
- · Inner diameter (d) — corresponds to the diameter of the shaft on which the bearing is installed in tension.
- · Outer diameter (D) — If the part to be selected does not have an outer working ring, the exact outer diameter can only be measured in the seat.
- · Width (B) is the height between the base ends of the outer and inner rings, taking into account the presence of a locking ring or collar.
For high-quality installation of certain types of bearings, special mounting parts, bushings, washers, rings, brackets or screws are required. They can be included in the kit supplied by the manufacturer, or they can be selected in the catalog according to size parameters.
The development and implementation of innovative materials in the field of bearing production makes it possible to significantly increase their operational life. With the help of the reference book, you can select an analog or original product with higher quality and performance characteristics. Access to the website is free for everyone and does not require prior registration. The information provided on bearings is expert.
