Decoding SKF 6206-2Z/C3LHT55
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- 2Z/C3LHT55Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6206-2Z/C3LHT55 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 16 mm (30 x 62 x 16 mm).

SKF deep groove ball bearings carrying the 2Z/C3LHT suffixes handle radial and axial loads where dust protection and elevated temperatures are concerns. Two steel shields, identified by 2Z, keep grease in and solid particles out. The C3 designation provides extra internal clearance, and the LHT lubricant is formulated for high-temperature service, making these bearings a common choice for electric motors, fans, and similar industrial equipment.
Reading the code helps when ordering a replacement. The base number, such as 6003, 6205, or 6302, defines the size and dimension series. The 2Z suffix means a metal shield sits on each side of the bearing. C3 indicates radial internal clearance above the standard value, which gives room for thermal expansion and lowers the chance of seizure. LHT23 or LHT55 identifies the factory-filled high-temperature grease. So a 6206-2Z/C3LHT23 is a 62-series bearing with two shields, C3 clearance, and high-temperature grease.
Typical installations include low- and medium-power electric motors, fans and extractors, centrifugal pumps, compressors, conveyor belts, and agricultural machinery. Refrigeration equipment and transmission systems running above 100 °C also use them. Because they take combined loads and resist dust and moisture, they suit contaminated environments provided mounting and lubrication are handled correctly.
Selection depends on radial and axial load, speed, and working temperature. Choose C3 clearance when the inner and outer rings will see different temperatures, or when mounting tolerances call for it. The 2Z shields block solid particles effectively but do not seal against liquids; for water or vapor exposure, consider contact seals instead. LHT grease is made for high temperatures, so relubrication is usually unnecessary. Align the bearing properly during mounting and avoid impacts that could mark the raceways.
For interchangeability, SKF bearings in this series can be replaced by other brands using the same international designation. Check that the substitute's LHT suffix covers a similar temperature range and that C3 clearance is maintained. Performance is not identical across all manufacturers, so review the technical data before substituting. MR supplies SKF bearings and can help you confirm the right option for your application.

Frequently asked questions
- SKF 6206-2Z/C3LHT55 bearing: what are its dimensions?
- SKF 6206-2Z/C3LHT55 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 16 mm (30 x 62 x 16 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6206.
- What does the 2Z suffix mean on an SKF bearing?
- 2Z means the bearing has a metal shield on each side. These shields hold lubricant in and block large particles, but they are not liquid-tight.
- What is C3 clearance for in these bearings?
- C3 is a radial internal clearance larger than standard. It compensates for thermal expansion, reduces seizure risk, and eases mounting where high temperatures or interference fits are involved.
- What is the difference between LHT23 and LHT55?
- Both are high-temperature lubricant designations. LHT23 typically covers temperatures up to about 150 °C, while LHT55 handles higher temperatures, up to 200 °C. The operating temperature decides which one fits.
