- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- 2Z/GJNSuffix
- 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 2Z/GJN deep groove ball bearings handle radial and axial loads in both directions. Each bearing has two metal shields (2Z) that keep the factory grease in place and block solid particles, which suits equipment where relubrication is difficult and reliable operation matters. MR Industrial Accessories supplies this series as part of its bearing range for customers in the United States and several Latin American countries.
Reading the code helps you order correctly. The base number gives the size and series. The 2Z suffix means two steel shields, one per side. GJN identifies the grease packed at the factory. If you send us the complete code from the old bearing, we can match it or suggest an equivalent.
Typical uses include electric motors, centrifugal pumps, fans, conveyors, machine tools and automotive components. The shielded design works well in dusty or moderately humid areas, where the goal is to cut lubrication work and keep the bearing running. For food, chemical and petrochemical plants, the same bearing is common in maintenance workshops.
When selecting a bearing, check the radial and axial load, the speed and the environment. The 2Z shields stop solid contaminants but do not seal against liquids. If water or vapors are present, look at versions with rubber seals instead. During mounting, align shaft and housing carefully and do not strike the shields. The GJN grease is already in place and, under normal conditions, does not need to be added.
SKF bearings in this series can be interchanged with other brands that use the same basic designation and equivalent suffixes, such as FAG, NSK or NTN. Always confirm tolerances and grease type, because these can differ between manufacturers. For replacements, the safest method is to consult a specialist and provide the full code engraved on the original bearing.

Frequently asked questions
- SKF 6003-2Z/GJN bearing: what are its dimensions?
- SKF 6003-2Z/GJN 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 2Z suffix mean on an SKF bearing?
- It means the bearing has two metal shields, one on each side. They hold grease in and keep dust and particles out, but they are not watertight against liquids.
- Does GJN grease require maintenance?
- No. GJN grease is factory-filled for the life of the bearing under normal operating conditions. Relubrication is not needed, except in very severe or high-temperature applications.
- Can I replace an SKF 2Z/GJN bearing with another brand?
- Yes, if the other brand has the same basic designation and equivalent suffixes. Check tolerances and grease type, and if in doubt consult us with the complete code.
