NSK R 168B is a deep groove ball bearing reference, within Bearings. Request a quote for R 168B via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The NSK R series deep groove ball bearing is a single row bearing with inch dimensions, designed to withstand moderate radial and axial loads in both directions. It is used in equipment where the housing and shaft follow inch measurements, such as imported machinery, power tools and transmission equipment. MR Accesorios Industriales sells this NSK line and helps you identify the correct part number for your application.

The R series designation is read with the letter R followed by a number indicating the size, and sometimes a B suffix. For example, R 4B and R 168B correspond to bearings of the Inch Series with inch dimensions. The final letter B indicates a construction variant within the series, generally linked to the cage type or the internal design. To choose the correct bearing, it is essential to start from the complete part number and verify the inch measurements of the shaft and housing.

These bearings are used in industries such as food, textile, wood and metallurgy, where equipment with inch measurements abounds. They also appear in machine tools, pumps, fans and conveyors of American or British origin. In Argentina, they are commonly found in reconditioned production lines and in imported equipment that requires spare parts with this dimensional standard. MR Accesorios Industriales sells them to meet those requirements.

To select the right bearing, take into account the type of sealing or protection: open, with shields or with seals, depending on the level of contamination in the environment. Also check the internal clearance and the intended lubrication, since they influence performance and service life. When mounting it, ensure correct alignment between shaft and housing, and avoid blows that could damage the raceways. Proper lubrication and precise fitting are key to reliable operation.

If you need to replace a bearing from another brand with inch measurements, the NSK R series is usually interchangeable with other equivalent designations on the market, as long as the dimensions and execution type match. The reference alone is not enough: you must compare bore, outer and width diameters in inches, in addition to the sealing. MR Accesorios Industriales advises you to find the correct equivalence without risk of error.

To request a quote for the NSK R series bearing you need, send us the complete part number via WhatsApp, for example R 4B or R 168B, or the inch measurements of your equipment. At MR Accesorios Industriales we quote shortly and indicate the compatible alternative if needed. More than 80 years of experience in bearings and power transmission back us.

The final letter B indicates a variant within the series, generally associated with the cage type or a modification in the internal design. To confirm the exact execution, it is best to check with the complete part number and the inch measurements.
How do I know if an R series bearing is compatible with my equipment?
You must compare the inch dimensions: bore, outer and width diameters, along with the type of sealing. If you have the original part number or the shaft and housing measurements, send them via WhatsApp and we'll indicate the right equivalence.
What lubrication does an R series deep groove ball bearing use?
Lubrication depends on the application: grease for moderate speeds and contaminated environments, or oil for high speeds. It is important to follow the equipment manufacturer's recommendations and maintain an adequate lubricant film to avoid premature wear.
