INA Bearing models have different characteristics according to the design, which makes the applicability of various models for a particular purpose or less will be somewhat different. For example, the deep groove ball bearings can withstand moderate radial and axial load. Friction low, you can create a high precision to meet the requirements of various types of quiet operation. So they are more suitable for small and medium-sized electric motors.

Spherical roller bearings can withstand very high loads and self-aligning. Such characteristics make them suitable for use in such as heavy engineering, such works will be heavy duty, shaft deflection and misalignment of the situation.

Identify the quality of equipment, INA bearings, usually from the following aspects:

The packaging is clear

Under normal circumstances, the regular manufacturers brand has its own dedicated design staff external packaging design, and arrange for the production conditions to cross the border plant for the production of production, and product packaging to color in terms of a line should be very clear, mm unambiguous.

The Seal word is clear

Each bearing products are printed with its brand ", label on the rolling bearing product body. Although the font is very small, regular manufacturers products Seal technology printing and embossing before the untreated, although the font is small, but the concave deep, very clear. Under normal circumstances, the font of counterfeit products is not only fuzzy, due to rough printing technology, fonts floating on the surface, and some even can easily hand the serious erase or manual traces.

Miscellaneous sound

Left hand holding Rolling body sets the right hand toggle coat to make it rotate, and listen to the hybrid ring INA bearings during operation. Backward production conditions of the majority of counterfeit products, completely manual workshops operating, bearing the body in the production process will inevitably be braced with dust, sand impurities, so the bearing rotation when the hybrid ring or is not running smoothly . This is to determine whether the products from the strict production standards, and the key brand of machine operators of the regular vendors.

The surface is muddy traces of oil

Surface is muddy traces of oil we need to buy bearings should pay special attention. Due to the current anti-rust technology and advanced foreign manufacturing countries, there is a gap, so the bearing body rust treatment is easy to leave a thick traces of oil, hand contact feeling sticky viscous thick, while the foreign The original bearing is almost no traces of anti-rust oil. According to insiders, particularly careful in INA Bearing smell a special flavor, which is the taste of the anti-rust oil.

The chamfer whether uniform

Chamfering of the so-called bearing, which is the junction of the horizontal surface and vertical surface, bearing counterfeit products due to restrictions on production technology, the rougher edges of the site deal with unsatisfactory that we can easily identify.

About the individual bearing types of detailed information, including product features and have the design specifications, see the introduction of the individual bearing models. Rolling models not included in the table, usually only for a few specific purposes.

The form uses a relatively simple bearing models of classification. Symbols which are limited and therefore can not make a precise distinction, and some features are not only determined by the bearing design. For example, the configuration contains angular contact ball bearings or tapered roller bearings, its rigidity depends on the pre-load and running speed, running speed affected by the precision of the bearing and associated components, as well as cage design. Despite its limitations, in accordance with the form, or can choose the appropriate model of the bearing. Must also be noted that the total cost of the entire bearing arrangement and inventory considerations also affect the final choice.

In the design of bearing arrangement, as well as other important criteria that need to comply with, which include the carrying capacity and life, friction, the permissible speed range, INA Bearing internal cleaning or pre-load, lubrication and sealing. A separate chapter a detailed description of these standards in this catalog.
