The SKF 6206-2RS1/C3 is a single row deep groove ball bearing with a 30 mm bore, 62 mm outside diameter and 16 mm width, fitted with a contact rubber seal on both sides (2RS1) and C3 radial internal clearance. It belongs to the SKF Explorer performance class and, per SKF, carries a basic dynamic load rating of 20.3 kN and a basic static load rating of 11.2 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; 06 = bore code for 30 mm (06 x 5); 2RS1 = contact seals on both sides; C3 = radial internal clearance greater than normal.
The contact seals rub lightly on the inner ring, which keeps grease in and dust, water and washdown spray out better than a shield. The price of that protection is speed: SKF lists a limiting speed of 8,000 r/min for this sealed version, against 12,000 r/min for the shielded 6206-2Z/C3.

Typical applications
- Industrial electric motors

- Pumps and mixers in damp or dusty plant rooms
- Construction and quarry equipment auxiliaries
- Like-for-like replacement of a worn SKF 6206-2RS1/C3
Compatibility and replacement
Every 6206 bearing made to ISO 15 has the same 30 x 62 x 16 mm boundary dimensions, so this bearing fits wherever a 6206 with contact seals 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 6206-2Z/C3 is the same size.
Frequently asked questions
What is the difference between 6206-2RS1/C3 and 6206-2Z/C3?
Only the closures. The 6206-2Z has non-contact steel shields; the 2RS1 version has contact rubber seals. Per SKF, the limiting speed is 12,000 r/min for 2Z and 8,000 r/min for 2RS1; the load ratings are the same. Choose shields for speed and low friction, seals for dirt and moisture.
Is it the same as a 6206ZZ or 6206-2RS from another brand?
Dimensionally yes: all 6206 bearings share 30 x 62 x 16 mm under ISO 15. A ZZ marking corresponds to the 2Z shielded design and 2RS to this sealed design; load ratings and speeds differ between makers, and the figures on this page are the SKF values.
What do the load ratings mean in practice?
The basic dynamic load rating C (20.3 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 (11.2 kN) is the reference for heavy loads at very low speed or standstill.
