From alternators to conveyor belt systems and agricultural equipment, 6203 bearings have an extensively wide use application.
The 2RS suffix means contact seals on both faces. These keep grease in and dirt and moisture out, which is what you want anywhere the bearing is exposed rather than sitting inside a sealed housing. It’s the reason 2RS is the usual choice over a ZZ metal-shielded version outdoors or in dusty conditions. The bearing arrives greased and sealed for life — no packing or servicing needed before fitting.
You may see this bearing listed as 6203 2RS, 6203RS, 6203-RS or 6203 2RS1 depending on the brand. They all describe the same 17x40x12mm rubber-sealed bearing.
Every bearing is stocked here in the UK and shipped from our own unit. If you’re unsure whether this is the right size, measure the bore, outer diameter and width of your old bearing and check them against our size chart, or give us a call before you order.
