- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 09Bore
- Bore 45 mm (09 × 5).
- 2RS1/C3LHT23Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6309 is the standard ISO basic designation, which sets the bearing type, series and bore.

SKF deep groove ball bearings are single-row components that handle radial and axial loads in both directions, making them a common choice in power transmission. The 2RS1 variant includes rubber seals on both sides, while C3 indicates internal clearance greater than normal. MR Industrial Accessories supplies these bearings to customers across the United States and Latin America.
The part number tells you the series and size at a glance. The 60 series is extra-light, with 6024 as an example; the 62 series is light, covering 6206 and 6209; the 63 series is medium, such as 6309; and the 619 series is extra-light, represented by 61903. Suffixes add detail: 2RS1 means rubber seals on both sides, C3 means increased internal radial clearance, and LHT23 indicates a lubricant formulated for high temperatures.
These bearings appear in electric motors, centrifugal pumps, industrial fans, conveyor belts and agricultural machinery. Their ability to take combined loads at speed suits power transmission equipment. In food, textile or chemical plants where temperatures run high, the 2RS1 seals and LHT23 lubricant work together to support dependable operation and longer bearing life.
Selection depends on radial and axial load, rotation speed and the surrounding environment. The 2RS1 seal keeps out dust and moisture, but in very dirty conditions you may need extra sealing. Choose C3 clearance when thermal gradients are significant, because it allows for expansion. Confirm that LHT23 lubrication matches your operating temperature range. During mounting, align the bearing precisely and avoid impacts that could damage the raceways.
SKF deep groove ball bearings can be interchanged with other brands that use the same basic designation and suffixes, but sealing and lubrication performance may differ. When replacing, check that the complete code matches, suffixes included. If you are unsure, ask us and we will help you find the right option.

Frequently asked questions
- SKF 6309-2RS1/C3LHT23 bearing: what are its dimensions?
- SKF 6309-2RS1/C3LHT23 measures 45 mm across the bore and 100 mm across the outside diameter; its width is 25 mm (45 x 100 x 25 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6309.
- What does the 2RS1 suffix mean on an SKF bearing?
- The 2RS1 suffix indicates rubber seals on both sides. These seals block contaminants and keep lubricant in, which helps extend service life in demanding environments.
- When should I use a bearing with C3 clearance?
- C3 clearance is advisable when the bearing runs at high temperatures or with interference fits, because it compensates for thermal expansion and prevents the clearance from becoming too tight.
- Is LHT23 lubrication suitable for high temperatures?
- Yes, LHT23 is a high-temperature lubricant designed to maintain its properties under severe conditions. Check that your operating temperature range falls within its limits for best performance.
