NSK angular contact ball bearings are designed to support combined radial and axial loads in one direction. Their design with offset raceways and angular contact between balls and rings allows high speeds and high axial load capacity. They are used in applications requiring precision and rigidity, such as machine tool spindles, pumps, compressors and gearboxes. At MR Accesorios Industriales we sell them and advise you on choosing the most suitable one.
The designation of these NSK bearings is interpreted as follows: the basic number indicates the size, where the first two digits correspond to the bore diameter (for example, 72 for 72 mm) and the next two to the dimension series. The letter B indicates a 40° contact angle, and EA a high-capacity polyamide cage. The suffix T85MR indicates a polyamide cage with a working temperature up to 85 °C, and T7 refers to a polyamide cage with lubrication for high temperature. Examples: 7208 BEA T85MR, T7, 7309 BEA T85MR, T7.
These bearings are used in industries such as metalworking, petrochemicals, food processing and process industries. In Argentina they are found in milling machine and CNC lathe spindles, centrifugal pumps, screw compressors, gearboxes and transmission cases. Also in mining, cement and paper equipment. Their ability to support axial loads in one direction makes them ideal for paired arrangements, where two opposed bearings absorb loads in both directions.
To select the correct bearing, consider the axial and radial load, rotation speed and environmental conditions. Sealing can be open or with protective plates; for contaminated environments, choose sealed variants. Internal clearance and lubrication are critical: adequate lubrication extends service life. During mounting, it is essential to correctly align the housings and apply the recommended preload to achieve the necessary rigidity. If you need help, contact us.
There are equivalences between brands: angular contact bearings from other companies can be interchanged if dimensions and contact angle match. However, tolerances and capacities may vary. If you have another brand's part number, send it to us and we will indicate the compatible alternative. At MR Accesorios Industriales we sell NSK and other leading brands, and we can advise you to find the right replacement.

Frequently Asked Questions
- What does the T85MR suffix mean on an NSK bearing?
- The T85MR suffix indicates that the bearing has a polyamide cage with thermal resistance up to 85 °C. It is important to respect that limit to avoid deformation and premature failure.
- How do I choose between a 72 and a 73 bearing?
- The 72 series has a smaller section than the 73, so it supports less load but allows higher speeds. The choice depends on the load and available space. Ask us and we will advise you.
- Can I replace a bearing from another brand with an NSK one?
- Yes, if dimensions, contact angle and load capacity match. Send us the original part number and we will indicate the NSK or other brand equivalent that best fits.
