How to read SKF 6203-2Z/C3GWP
- 62Series
- Deep groove ball bearings, 62 series. For the same bore, each series has a different outside diameter and width.
- 03Bore
- 17 mm bore: code 03 stands for 17 mm by standard.
- 2Z/C3GWPSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6203 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The SKF deep groove ball bearing with 2Z and C3GWP suffixes is a medium-section component designed to support moderate radial and axial loads in both directions. Its construction includes two protective shields (2Z) that retain the lubricant and block particles, and a special long-life lubrication (GWP) that makes it suitable for applications where frequent relubrication is not expected. It is a reliable option for industrial equipment requiring low maintenance.
The designation of these bearings is interpreted as follows: the basic number, for example 6203 or 6205, indicates the size and series (series 62 corresponds to a medium section, with a balance between load capacity and space occupied). The suffix 2Z indicates that the bearing has two metal protective shields, one on each side, which prevent the entry of contaminants and the escape of lubricant. The suffix C3 indicates an internal radial clearance greater than standard, suitable for assemblies with interference fits or thermal differences between shaft and housing. Finally, GWP identifies a special lifetime lubrication, formulated to withstand demanding operating conditions without the need for relubrication.
These bearings are used in a wide variety of industrial applications in Argentina. They are common in electric motors, centrifugal pumps, fans, gearboxes, conveyors and machine tools. Industries such as food, chemical, petrochemical and metallurgical choose them for their versatility and low maintenance. They also appear in refrigeration equipment, compressors and power transmission systems. Their ability to work at moderate and high speeds makes them suitable for rotating equipment in general.
To correctly select a bearing of this type, take into account the radial and axial load it must support, the rotation speed, the type of fit on shaft and housing, and the environmental conditions. The 2Z seal is appropriate for environments with moderate dust or humidity, but not for immersion. C3 clearance is recommended when the fit is interference or there are thermal gradients. GWP lubrication is already applied and does not require additional maintenance under normal conditions. During mounting, ensure correct alignment and avoid impacts that could damage the raceways or shields.
Regarding equivalences and interchangeability, deep groove ball bearings with similar suffixes from other brands may be compatible, but always verify the critical dimensions and operating conditions. The SKF designation of these bearings may have equivalents in other manufacturers' catalogs, although the lubrication and clearance suffixes may vary. Do not assume that a similar code offers the same performance; consult each manufacturer's technical specifications. At MR Accesorios Industriales we can help you find the right reference.

Frequently Asked Questions
- What are the dimensions of the SKF 6203-2Z/C3GWP bearing?
- The SKF 6203-2Z/C3GWP bearing has a 17 mm bore, a 40 mm outside diameter and a 12 mm width (17 x 40 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6203.
- What does the C3 suffix mean on a bearing?
- The C3 suffix indicates an internal radial clearance greater than standard. It is used when the assembly has interference fits or when there are temperature differences between the shaft and housing, to prevent the bearing from becoming preloaded.
- Does this bearing need relubrication?
- No, the GWP designation indicates that it comes with a special lifetime lubrication. Under normal operating conditions it does not require relubrication, which reduces maintenance and extends its service life.
- Can I replace an SKF bearing with one from a different brand?
- Yes, as long as the dimensions and tolerances are equivalent. However, the lubrication and clearance suffixes may vary between manufacturers. Verify the technical specifications and consult us to ensure compatibility.
