- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- 2RSH/GJNSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6303 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF deep groove ball bearings with the 2RSH/GJN suffix are sealed, pre-lubricated bearings built for low friction and long service life. The double 2RSH contact seal blocks contamination, while the GJN grease resists water and high temperatures. They are commonly used in electric motors, pumps, fans and general industrial equipment.
The part number tells you what you are getting. The numeric prefix covers size and series, such as 6003, 6205 or 6304; the first digits identify the bearing type and the last two the bore diameter. The 2RSH suffix means two synthetic rubber contact seals, one on each side, which keep grease in and contaminants out. The GJN suffix identifies the polyurea grease used at the factory. So a bearing like 6203-2RSH/GJN is a 62 series bearing with 2RSH seals and GJN grease.
These bearings appear in electric motors, centrifugal pumps, fans, compressors, machine tools, conveyors and agricultural equipment. The sealed design suits dusty, humid or moderately exposed environments, and they are common in metallurgical, food, chemical and automotive operations. For equipment that runs continuously, they are a practical choice.
When selecting a 2RSH/GJN bearing, check the load, rotation speed and environmental conditions. The 2RSH seal is right where particles and moisture are a concern, but seal friction makes it less suitable for high speeds. GJN grease works across a wide temperature range, though you should always confirm the specific conditions. During mounting, keep alignment correct and avoid striking the seals. Relubrication is not needed because they come lubricated for life.
For equivalences, SKF bearings with the 2RSH/GJN suffix can be interchanged with bearings from other brands that have similar specifications, such as double contact seals and polyurea grease. Always verify dimensions and tolerances against the applicable standard. Alternatives with equivalent designations exist from brands like FAG, NSK or NTN, but compatibility must be confirmed.

Frequently asked questions
- SKF 6303-2RSH/GJN bearing: what are its dimensions?
- SKF 6303-2RSH/GJN measures 17 mm across the bore and 47 mm across the outside diameter; its width is 14 mm (17 x 47 x 14 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6303.
- What does the 2RSH suffix mean on an SKF bearing?
- It means the bearing has two synthetic rubber contact seals, one per side. They retain grease and block contaminants, which supports longer service life in demanding environments.
- What is GJN grease and what temperatures does it handle?
- GJN is a high-quality polyurea grease with good water and high-temperature resistance. It is generally suitable from -30 °C to +150 °C, but always check the technical specifications for critical applications.
- How do I request a quote for SKF 2RSH/GJN bearings?
- Send the exact bearing part number by WhatsApp or email. Our team will reply promptly with a quote. If you are not sure of the part number, we can help you identify it and suggest equivalents.
