Decoding SKF 6003-2RSH/C3GJN
- 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.
- 2RSH/C3GJNSuffix
- 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 6003-2RSH/C3GJN 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 deep groove ball bearings with double-sided seals, increased internal clearance, and factory-filled high-temperature grease are precision components for demanding environments. They retain lubricant, keep contaminants out, and handle thermal expansion, making them suitable for electric motors, pumps, fans, and transmission equipment. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The part number breaks down into distinct elements: the basic number (such as 6001, 6200, or 6202) identifies the series and size; the 2RSH suffix denotes a nitrile contact seal on both sides; C3 or C4 indicates radial internal clearance greater than normal; and GJN refers to a polyurea grease rated for temperatures up to 150 °C. For example, 6004-2RSH/C3GJN combines sealing, C3 clearance, and high-temperature lubrication in one code.
These bearings are common in food, chemical, cement, and automotive industries, as well as in electric motors, centrifugal pumps, fans, compressors, conveyor belts, and machine tools. In food and beverage plants, frequent washdowns demand seals that resist water and moisture, while metalworking operations with varying loads and temperatures benefit from the correct internal clearance.
Selection depends on speed, load, and operating temperature. The 2RSH seal suits dusty, wet, or vaporous environments but is not intended for immersion. C3 or C4 clearance compensates for thermal expansion and interference fits; with a steel housing and moderate temperatures, normal clearance may suffice. GJN grease is pre-filled, so washing or unnecessary re-greasing is not advised. During mounting, ensure alignment and use proper tools to avoid damaging the seals.
Equivalent deep groove ball bearings with seals and increased clearance are available from other brands under similar designations, though suffixes can differ. When replacing, do not rely on the basic number alone: confirm that sealing, clearance, and lubrication match your equipment's conditions. If unsure, send us the full code and we will help.

Frequently asked questions
- SKF 6003-2RSH/C3GJN bearing: what are its dimensions?
- SKF 6003-2RSH/C3GJN 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 2RSH suffix mean on an SKF bearing?
- 2RSH indicates nitrile contact seals on both sides. These seals retain grease and block dust, water, and contaminants, making the bearing suitable for dirty or humid environments.
- When should I choose a bearing with C3 clearance instead of normal clearance?
- C3 clearance is recommended when there are thermal differences between inner and outer rings, interference fits, or high speeds. The increased clearance prevents preload and overheating.
- Can the GJN grease in these bearings be re-greased?
- GJN grease is factory-dosed for the bearing's service life under normal conditions. Re-greasing or washing is not recommended, as it can introduce contamination or degrade the original lubricant.
