The 685 is a miniature deep groove ball bearing with a 5 mm bore and 11 mm outside diameter. The OPEN version has no metal shields or rubber seals on either side, with a 3 mm width. Because there is no built-in shielding, lubrication supply and retention — along with protection against external contaminants — are handled by the surrounding housing or by the design around the bearing. This version typically fits applications where lubrication and protection are already managed at the system level, or where you need direct control over how the bearing is lubricated. Suitability still depends on the actual operating conditions.
With no side shields, the key points to confirm are how lubrication is supplied and retained, and whether the operating environment contains dust, moisture or cutting fluids. In cleaner environments, or where the housing already provides a sealed cavity, the OPEN version can be considered. If the bearing is exposed to heavier contamination, it's worth discussing whether a shielded or sealed version would suit better. ISK Bearings can help assess this based on the details you share.
To help confirm whether the 685 OPEN suits your application, it helps to share: (1) operating speed range; (2) operating environment (dust, moisture or chemical exposure); (3) how lubrication is supplied (system-fed oil or grease). If you already have a part number, drawing or sample, feel free to include it, and ISK will help evaluate the specification and supply options.
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.
