The SKF 6001-2Z/C3 is a single row deep groove ball bearing with a 12 mm bore, 28 mm outside diameter and 8 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 5.4 kN and a basic static load rating of 2.36 kN.
The designation can be read directly: 6 = single row deep groove ball bearing, 0 = ISO dimension series 10 (extra-light), the thinnest cross-section of the three common series, used where radial space is limited; 01 = bore code for 12 mm; 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 30,000 r/min for this version. That makes the 2Z design the usual choice for electric motors, fans and other clean, fast-running positions.

Typical applications
- Office machines and light automation axes
- Centrifugal pumps and pump motors
- Electric motors and generators (drive-end and non-drive-end positions)
- Gearbox input shafts and speed reducers
- Like-for-like replacement of a worn SKF 6001-2Z/C3
Compatibility and replacement
Every 6001 bearing made to ISO 15 has the same 12 x 28 x 8 mm boundary dimensions, so this bearing fits wherever a 6001 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 6001-2RSH/C3 is the same size.
Frequently asked questions
What is the difference between 6001-2Z/C3 and 6001-2RSH/C3?
Only the closures. The 6001-2Z has non-contact steel shields; the 2RSH version has contact rubber seals. Choose shields for speed and low friction, seals for dirt and moisture.
What does C3 mean, and can I use a bearing without it?
C3 is a radial internal clearance greater than normal. It leaves room for the inner ring to expand with a tight shaft fit or with heat, which is why electric motors and hot-running machines often specify it. Fit the clearance class the machine maker specifies or that is marked on the old bearing; do not swap C3 for normal clearance without checking.
Does the 6001-2Z/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 0.0217 kg.
