- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- 2Z/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF deep groove ball bearings handle radial and axial loads in industrial equipment. Their single-row ball design supports high speeds with minimal maintenance. MR Industrial Accessories supplies the SKF brand so your machinery stays reliable. To replace a bearing, send the part number by WhatsApp or email and we will quote it.
The part number tells you what you are getting. Take 6000-2Z/C2: 6000 is the size and series, 2Z means two metal shields (ZZ), and after the slash, C2 is the internal radial clearance, which is tighter than standard. In 6001-Z/C3, Z is a single shield and C3 is a larger clearance. Reading these suffixes helps you match the bearing to the application.
These bearings appear in electric motors, centrifugal pumps, conveyors, fans and machine tools. They support combined loads and run at high speeds, so they fit drive shafts and rollers in food, textile and metallurgical plants. The 60 series is common in small and medium-power equipment.
Selection comes down to sealing and clearance. 2Z shields keep out dust and dirt but do not retain lubricant the way a 2RS seal does. Choose C2 or C3 according to housing fits and operating temperature; C3 compensates for thermal expansion. Correct lubrication and alignment also affect service life. If you are unsure, ask us.
When replacing, cross-brand equivalents are common: an SKF 6000-2Z can interchange with similar part numbers from other makers if dimensions and suffixes match. Not all suffixes are equivalent between manufacturers, so verify the full part number and specifications. We can help you identify the right option.
If you have the part number, send it by WhatsApp or email for a prompt quote. We can also help you identify a bearing if needed. MR Industrial Accessories serves customers across the United States and in several Latin American countries.

Frequently asked questions
- SKF 6307-2Z/C3 bearing: what are its dimensions?
- SKF 6307-2Z/C3 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 21 mm (35 x 80 x 21 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6307.
- What does the 2Z suffix mean on an SKF bearing?
- 2Z indicates two metal shields, one on each side, that block dust and dirt. They do not retain lubricant as effectively as rubber seals.
- What is the difference between C2 and C3 clearance?
- C2 internal radial clearance is smaller than standard; C3 is larger. The choice depends on mounting conditions and temperature, with C3 used for thermal expansion or tighter fits.
- Can I replace an SKF bearing with another brand?
- Yes, if the main dimensions and suffixes match. Tolerances and materials can vary, so verify the full part number and contact us for compatibility.
