Questions
What size is a 6908-2RS bearing?
40 × 62 × 12 mm (bore × outside diameter × width).
What does 2RS mean?
2RS means rubber seals on both sides. Seals keep out dirt and water better than metal shields, which makes them a good default for farm, outdoor and wet equipment.
Is 6908-2RS the same as 6908-2RSH or 6908LLU?
Yes. They share the same size and seal type. Brands just use different suffixes: SKF uses 2RSH, NTN uses LLU, NSK uses DDU and FAG uses 2RSR.
