SKF deep groove ball bearings are essential components for supporting radial and axial loads in industrial machinery. Their single-row ball design allows high speeds and low maintenance. At MR Accesorios Industriales we carry the SKF brand so your equipment runs reliably. If you need to replace a bearing, send us the part number on WhatsApp and we will quote you.
The designation of these SKF bearings follows a clear system. For example, in 6000-2Z/C2, 6000 indicates the size and series; the 2Z suffix indicates that it has two protective metal shields (ZZ); the slash / separates the tolerance suffix C2, which implies an internal radial clearance smaller than standard. In 6001-Z/C3, Z indicates a single shield and C3 a larger clearance. These part numbers allow you to choose the right bearing for the application.
These bearings are used in a wide variety of industries in Argentina: from electric motors and centrifugal pumps to conveyors, fans and machine tools. Their ability to support combined loads and rotate at high speeds makes them versatile. In food, textile or metallurgical plants, you will find them on drive shafts and rollers. The 60 series is particularly common in small and medium-power equipment.
To select correctly, take into account the type of sealing: 2Z offers protection against dust and dirt, but it does not retain lubricant like a 2RS seal. The C2 or C3 clearance is chosen according to housing tolerances and operating temperature; a larger clearance (C3) compensates for thermal expansion. Proper lubrication and precise alignment are key to maximizing service life. If you have doubts, contact us.
When replacing, it is common to find cross-brand equivalents: an SKF 6000-2Z bearing can be interchanged with similar part numbers from other brands, as long as dimensions and suffixes match. But note: not all suffixes are equivalent between manufacturers. Always verify the full part number and specifications. At MR Accesorios Industriales we can help you identify the best option for your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 6313-Z/C3 bearing?
- The SKF 6313-Z/C3 bearing has a 65 mm bore, a 140 mm outside diameter and a 33 mm width (65 x 140 x 33 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6313.
- What does the 2Z suffix mean on an SKF bearing?
- The 2Z suffix indicates that the bearing has two metal shields (one on each side) that prevent dust and dirt from entering, but they do not retain lubricant as effectively as a rubber seal.
- What is the difference between C2 and C3 clearance?
- C2 internal radial clearance is smaller than standard, while C3 is larger. They are selected according to mounting conditions and temperature: C3 is used when there is thermal expansion or tighter fits.
- Can I replace an SKF bearing with another brand?
- Yes, as long as the main dimensions and suffixes match. However, tolerances and materials may vary between manufacturers. We recommend verifying the full part number and contacting us to ensure compatibility.
