How to read SKF 6003-2RSL/LHT23
- 60Series
- Deep groove ball bearings, 60 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.
- 2RSL/LHT23Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6003 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF RSL/LHT series deep groove ball bearings are single-row sealed bearings designed to carry moderate radial and axial loads in applications where the operating temperature is high. Their double-sided seals and high-temperature grease make them suitable for demanding environments such as ovens, electric motors and industrial equipment operating under severe conditions. MR Accesorios Industriales carries this line as part of its SKF bearing catalogue.
The designation of these bearings combines the basic series number with suffixes that indicate specific characteristics. For example, in 6002-2RSL/LHT23, the 2RSL indicates that the bearing has low-friction seals on both sides, while LHT23 identifies the high-temperature grease with which it is factory-lubricated. Examples in the series include bore diameters ranging from 15 mm to 20 mm, depending on the numeric code. This nomenclature makes it possible to quickly identify the sealing and lubrication characteristics without consulting additional tables.
These bearings are used in applications where temperatures exceed 100 °C, such as electric motors in industrial ovens, extraction fans, conveyors in foundries and process equipment in chemical plants. In Argentina, they are common in the food industry (bakery ovens), ceramics, glass and metallurgy. Their ability to withstand high temperatures without losing lubrication makes them ideal for environments where standard bearings would fail prematurely.
To select the right bearing, take into account the shaft diameter, radial and axial loads, and the operating temperature. The 2RSL seal offers low friction and protection against contaminants, but it is not suitable for immersion. The LHT23 grease is formulated for high temperatures, with a range that typically reaches up to 150 °C. During mounting, ensure correct alignment and avoid striking the seals. Lubrication is for life, so no additional maintenance is required.
As for equivalents, SKF bearings in this series can be interchanged with those from other brands that follow the same international designation, such as FAG, NSK or NTN, provided the dimensions and the sealing and lubrication specifications match. It is important to verify the full part number, since small changes in the suffixes indicate differences in sealing or grease. For replacements, it is always advisable to consult a specialist and provide the exact part number of the original bearing.

Frequently Asked Questions
- What are the dimensions of the SKF 6003-2RSL/LHT23 bearing?
- The SKF 6003-2RSL/LHT23 bearing has a 17 mm bore, a 35 mm outside diameter and a 10 mm width (17 x 35 x 10 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6003.
- What does the LHT23 suffix mean on these bearings?
- LHT23 indicates that the bearing is factory-lubricated with a high-temperature grease, suitable for continuous service where the temperature exceeds 100 °C. This grease has a synthetic base and additives that extend service life under severe conditions.
- What is the maximum operating temperature?
- LHT23 grease is designed to withstand up to 150 °C continuously. However, the maximum temperature also depends on the seal and the cage material. For applications above that value, we recommend consulting our technical team.
- Can they be mounted in any position?
- Yes, sealed deep groove ball bearings can be mounted in any orientation. However, for applications with significant axial loads, it is preferable to mount them with the seal side that carries the fixed load. Follow the manufacturer's recommendations for correct mounting.
