The SKF 6207-2Z/C3 is a single row deep groove ball bearing with a 35 mm bore, 72 mm outside diameter and 17 mm width, fitted with a non-contact metal shield on both sides (2Z) and C3 radial internal clearance. It belongs to the SKF Explorer performance class and, per SKF, carries a basic dynamic load rating of 27 kN and a basic static load rating of 15.3 kN.
The designation can be read directly: 6 = single row deep groove ball bearing, 2 = ISO dimension series 02 (light), the most widely used series, balancing size and load capacity; 07 = bore code for 35 mm (07 x 5); 2Z = shields on both sides; C3 = radial internal clearance greater than normal.
Shields leave a narrow gap to the inner ring, so friction stays low and SKF lists a limiting speed of 10,000 r/min for this version, compared with 6,300 r/min for the sealed 6207-2RS1/C3. That makes the 2Z design the usual choice for electric motors, fans and other clean, fast-running positions.

Typical applications

- Centrifugal pumps and pump motors
- Gearbox input shafts and speed reducers
- Like-for-like replacement of a worn SKF 6207-2Z/C3
Compatibility and replacement
Every 6207 bearing made to ISO 15 has the same 35 x 72 x 17 mm boundary dimensions, so this bearing fits wherever a 6207 with shields and C3 clearance from another maker was used. Suffixes differ between brands: shields are often marked ZZ or 2Z, contact seals 2RS, 2RS1, DDU or LLU, and the clearance C3 may appear as “C3” or “/C3”. Always match the sealing arrangement and the clearance class shown on the old bearing; if your machine needs the other closure, the 6207-2RS1/C3 is the same size.
Frequently asked questions
What is the difference between 6207-2Z/C3 and 6207-2RS1/C3?
Only the closures. The 6207-2Z has non-contact steel shields; the 2RS1 version has contact rubber seals. Per SKF, the limiting speed is 10,000 r/min for 2Z and 6,300 r/min for 2RS1; the load ratings are the same. Choose shields for speed and low friction, seals for dirt and moisture.
Does the 6207-2Z/C3 need greasing?
No. Per SKF it is supplied filled with grease and has no relubrication feature, so it is mounted as delivered and not washed out. Net weight per SKF is 0.293 kg.
Is it the same as a 6207ZZ or 6207-2RS from another brand?
Dimensionally yes: all 6207 bearings share 35 x 72 x 17 mm under ISO 15. A ZZ marking corresponds to this shielded design and 2RS to the sealed design; load ratings and speeds differ between makers, and the figures on this page are the SKF values.
