Decoding SKF 6003-2RSL/LHT23
- 60Series
- Deep groove ball bearings, 60 series. Series differ in outside diameter and width even when the bore is the same.
- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- 2RSL/LHT23Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6003 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6003-2RSL/LHT23 measures 17 mm across the bore and 35 mm across the outside diameter; its width is 10 mm (17 x 35 x 10 mm).

SKF RSL/LHT deep groove ball bearings are single-row, sealed units built for moderate radial and axial loads where heat is a factor. Both sides carry low-friction seals, and the bearing comes from the factory packed with high-temperature grease. That combination suits ovens, electric motors and other industrial equipment running in tough conditions. MR Industrial Accessories supplies this line as part of its SKF bearing range.
Reading the part number tells you most of what you need. Take 6002-2RSL/LHT23: the 2RSL block means low-friction seals on both faces, and LHT23 points to the high-temperature grease used at assembly. Bore sizes in this series run from 15 mm to 20 mm, depending on the numeric code. With that structure, you can identify sealing and lubrication details without opening a catalog.
These bearings fit equipment that runs above 100 °C: motors on industrial ovens, extraction fans, foundry conveyors and process machinery in chemical plants. They also appear in bakery ovens, ceramics, glass and metallurgy operations. Because the grease holds up under heat, they stay lubricated where a standard bearing would break down early.
When choosing a bearing, check shaft diameter, radial and axial loads, and operating temperature. The 2RSL seal keeps friction low and blocks contaminants, though it is not meant for immersion. LHT23 grease is formulated for high temperatures and typically handles up to 150 °C. Mount with proper alignment and do not strike the seals. The lubrication lasts for the life of the bearing, so no extra maintenance is needed.
For equivalents, SKF bearings in this series interchange with other brands using the same international designation, such as FAG, NSK or NTN, as long as dimensions and sealing and lubrication specs line up. Check the complete part number carefully: a small suffix change can mean different seals or grease. For replacements, it pays to talk to a specialist and have the original part number on hand.

Frequently asked questions
- SKF 6003-2RSL/LHT23 bearing: what are its dimensions?
- SKF 6003-2RSL/LHT23 measures 17 mm across the bore and 35 mm across the outside diameter; its width is 10 mm (17 x 35 x 10 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6003.
- What does the LHT23 suffix mean on these bearings?
- LHT23 indicates the bearing is factory-lubricated with a high-temperature grease for continuous service above 100 °C. The 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. The maximum also depends on the seal and cage material. For applications above that value, consult 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.
