The SKF 6008-2RS1/C3 is a single row deep groove ball bearing with a 40 mm bore, 68 mm outside diameter and 15 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 17.8 kN and a basic static load rating of 11 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; 08 = bore code for 40 mm (08 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 6,300 r/min for this sealed version, against 11,000 r/min for the shielded 6008-2Z/C3.

Typical applications
- Industrial electric motors
- Idlers, pulleys and tensioners
- Agricultural and food-processing machinery that is washed down
- Belt and roller conveyors exposed to dust
- Like-for-like replacement of a worn SKF 6008-2RS1/C3
Compatibility and replacement
Every 6008 bearing made to ISO 15 has the same 40 x 68 x 15 mm boundary dimensions, so this bearing fits wherever a 6008 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 6008-2Z/C3 is the same size.
Frequently asked questions
What is the difference between 6008-2RS1/C3 and 6008-2Z/C3?
Only the closures. The 6008-2Z has non-contact steel shields; the 2RS1 version has contact rubber seals. Per SKF, the limiting speed is 11,000 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.
What do the load ratings mean in practice?
The basic dynamic load rating C (17.8 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 kN) is the reference for heavy loads at very low speed or standstill.
Does the 6008-2RS1/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 0.191 kg.
