SKF deep groove ball bearings of the 60 and 62 series with 2RS1 seals and NR retaining ring are components designed to support radial and axial loads in both directions. Their sealed construction makes them ideal for environments with dust or moisture, and the NR ring facilitates axial mounting in housings. MR Accesorios Industriales supplies this line as part of its extensive bearing catalogue.

The designation of these bearings combines the series number with suffixes that indicate specific characteristics. For example, in 6006-2RS1NR, the prefix 60 corresponds to the extra light section series, while 62 identifies the medium section series, as in 6206-2RS1NR. The suffix 2RS1 indicates that the bearing has rubber seals on both sides, which provides an effective barrier against contaminants. The NR indicates the presence of a retaining ring on the outer ring, which allows the bearing to be fixed axially in the housing without the need for side covers. This combination of suffixes is common in applications where protection and positioning are required.

These bearings are used in a wide variety of industries in Argentina, such as food, textile, metallurgical and agricultural. They are common in electric motors, pumps, fans, conveyors and transmission machinery. Thanks to their seals, they withstand environments with dust, chips or liquids, which makes them suitable for equipment exposed to demanding conditions. The NR ring simplifies mounting on shafts where reliable axial fixing is needed, avoiding the use of additional components.

To correctly select a sealed bearing with retaining ring, take into account the radial and axial load it will have to support, as well as the rotation speed. Verify that the housing has the appropriate groove for the NR ring and that the shaft meets the recommended tolerances. During mounting, avoid hitting the seals and ensure correct alignment between shaft and housing. Lubrication is already built in at the factory and the seals keep the lubricant in place, but it is important not to expose them to extreme temperatures.

As for equivalences, SKF bearings with 2RS1 and NR suffixes can be interchanged with products from other brands that follow the same standardized designation. However, dimensions and load capacities may vary slightly between manufacturers. Therefore, it is always advisable to verify the complete part number and the technical specifications before replacing a bearing. At MR Accesorios Industriales we can advise you on interchangeability and available options.

Frequently Asked Questions

What are the dimensions of the SKF 6306-2RS1NR bearing?
The SKF 6306-2RS1NR bearing has a 30 mm bore, a 72 mm outside diameter and a 19 mm width (30 x 72 x 19 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6306.
What does the 2RS1 suffix mean on an SKF bearing?
The 2RS1 suffix indicates that the bearing has rubber seals on both sides. These seals protect against the entry of contaminants and retain the lubricant, extending the service life of the bearing in harsh environments.
What is the NR retaining ring for?
The NR ring is a spring ring that is inserted into a groove in the outer ring and allows the bearing to be fixed axially in the housing. This simplifies the design and avoids the use of additional covers or flanges.
Can I replace an SKF 2RS1NR bearing with another brand?
Yes, as long as the standardized designation matches in dimensions and suffixes. However, verify the tolerances and load capacities, as they may vary between manufacturers. Contact us on WhatsApp for advice.
