How to read SKF 6303-2RSL
- 63Series
- Deep groove ball bearings, 63 series. For the same bore, each series has a different outside diameter and width.
- 03Bore
- 17 mm bore: code 03 stands for 17 mm by standard.
- 2RSLSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6303 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The SKF deep groove ball bearing with the 2RSL suffix is a low-friction sealed component that combines the radial and axial load capacity of this family with effective protection against contaminants. It is used in equipment requiring low friction and long service life, such as electric motors, pumps and fans. MR Accesorios Industriales supplies this line.
The designation of these bearings follows the SKF system: the basic number indicates the size and series (for example, 6000, 6200). The 2RSL suffix indicates that the bearing has low-friction seals on both sides, which reduces torque and improves lubricant retention. In the examples 6000-2RSL and 6200-2RSL, the numeric prefix defines the dimensions; the suffix is common to all. Knowing this nomenclature allows you to quickly identify the right product.
These bearings are used in a wide variety of industries in Argentina: from low-power electric motors to centrifugal pumps, fans, conveyor belts and agricultural machinery. Their sealed design makes them suitable for environments with moderate dust or humidity, where particle ingress must be prevented without sacrificing speed. They are a reliable option for equipment operating continuously.
To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. The 2RSL seal offers low friction, but if there is exposure to liquids or abrasive dust, evaluate a more robust seal. During mounting, ensure precise alignment and avoid impacts that damage the seals. Lubrication comes from the factory; adding grease is not necessary, but check that the environment is clean.
Regarding equivalents, deep groove ball bearings with low-friction seals from other brands can be interchanged if dimensions and tolerances match. SKF is a global reference, and MR Accesorios Industriales supplies it as a brand. Always check the complete code and technical specifications before replacing one bearing with another from a different manufacturer.

Frequently Asked Questions
- What are the dimensions of the SKF 6303-2RSL bearing?
- The SKF 6303-2RSL bearing has a 17 mm bore, a 47 mm outside diameter and a 14 mm width (17 x 47 x 14 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6303.
- What does the 2RSL suffix mean on an SKF bearing?
- The 2RSL suffix indicates that the bearing has low-friction seals on both sides. These seals reduce torque and protect against contaminant ingress, extending bearing service life in applications where energy efficiency is required.
- Does this bearing come factory-lubricated?
- Yes, SKF bearings with the 2RSL suffix are supplied lubricated for life. No additional grease is needed during mounting, which simplifies maintenance and prevents over-lubrication errors.
- Can I replace a 2RSL bearing with a 2RS one?
- In many cases yes, but keep in mind that the 2RS seal offers greater protection against contaminants, although with higher friction. If your application requires low friction, the 2RSL is more suitable. Always check the operating conditions.
