The SKF 6202-2Z/C3 is a single row deep groove ball bearing with a 15 mm bore, 35 mm outside diameter and 11 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 8.06 kN and a basic static load rating of 3.75 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; 02 = bore code for 15 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 22,000 r/min for this version, compared with 13,000 r/min for the sealed 6202-2RSH/C3. 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
- Compressors and vacuum pumps
- Electric motors and generators (drive-end and non-drive-end positions)
- Centrifugal pumps and pump motors
- Like-for-like replacement of a worn SKF 6202-2Z/C3
Compatibility and replacement
Every 6202 bearing made to ISO 15 has the same 15 x 35 x 11 mm boundary dimensions, so this bearing fits wherever a 6202 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 6202-2RSH/C3 is the same size.
Frequently asked questions
What is the difference between 6202-2Z/C3 and 6202-2RSH/C3?
Only the closures. The 6202-2Z has non-contact steel shields; the 2RSH version has contact rubber seals. Per SKF, the limiting speed is 22,000 r/min for 2Z and 13,000 r/min for 2RSH; the load ratings are the same. Choose shields for speed and low friction, seals for dirt and moisture.
Does the 6202-2Z/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 0.0465 kg.
What do the load ratings mean in practice?
The basic dynamic load rating C (8.06 kN) is used to calculate rating life: under ISO 281, a ball bearing loaded at one tenth of C has a basic rating life of 1,000 million revolutions. The static rating C0 (3.75 kN) is the reference for heavy loads at very low speed or standstill.
