6306 is a single-row deep groove ball bearing with a bore (d) of 30mm, outer diameter (D) of 72mm and width (B) of 19mm. The OPEN version has no shields and no seals — both raceway sides are exposed. This means lubrication and protection against external contaminants are not handled by the bearing itself, but by the surrounding equipment design, such as an external oil supply, an oil bath, or an existing enclosed housing.
Because there is no built-in shielding, lubrication method and external protection are the two key points to check for this version. It helps to first confirm: whether the operating environment already provides external oiling or an oil bath, whether dust, moisture or coolant may enter the surrounding area, and how re-greasing or oil-change intervals are planned. Suitability still needs to be confirmed against actual operating conditions.
If you can share the rotational speed, load direction and operating environment (enclosed housing vs. a more exposed setting), we can help assess whether OPEN is the right version, or whether a shielded/sealed version should be considered instead. If you already have a part number, drawing or sample, feel free to include it. Share your application background and estimated quantity, and we will help evaluate the selection and provide a quotation.
Some non-standard or currently out-of-stock bearings may not be immediately available. If you have specific requirements, feel free to contact us — we will do our best to confirm lead times and provide alternative solutions.
