Ball Casters Size: 25MM_6MM Color: 4 upper 4 lower Item weight: 0.11 pounds Product highlights Smooth rolling: Precision ball caster design reduces friction for quieter, easier movement across flat surfaces. Compact size: 25MM_6MM profile fits applications where space is limited while still providing dependable rolling performance. Lightweight: At 0.11 pounds, the set adds minimal weight to the item it serves, making it suitable for portable or delicate assemblies. Clear configuration: Color listing shown as 4 upper 4 lower for easy identification and installation. Key benefits Improves mobility: Converts fixed bases into mobile components, making repositioning and transport simpler and faster. Protects floors and surfaces: Rolling action reduces drag that can scratch or scuff underlying materials. Simplifies maintenance: Easy to access and when wear occurs, restoring smooth function without full component replacement. Versatile fit: Intended for use in assemblies that accept a 25MM_6MM ball caster size. What it does and how it performs Function: Facilitates multidirectional movement using a ballinsocket style caster element designed to rotate and change direction with low resistance. Performance: Engineered for consistent rolling behavior under normal load conditions in small to medium duty applications. Compatibility: Suitable for devices and fixtures that require a 25MM_6MM ball caster specification. Verify mounting dimensions before installation. Practical use scenarios Furniture retrofit: worn glides on small tables, cabinets, or display stands to restore mobility and ease rearrangement. Equipment carts and trays: Add or casters on lightweight carts, instrument trays, or sampling stands to improve handling. Prototype and robotics: Use in small robotics platforms or prototype assemblies where compact, omnidirectional rolling elements are needed. What to check before Confirm the 25MM_6MM size matches your mounting or socket dimensions. Verify the color configuration labeled as 4 upper 4 lower meets your visual or placement needs. Ensure the expected load and operating surface are suitable for light to moderate duty ball casters. This product provides a compact, lightweight solution for restoring or adding smooth rolling motion to compatible smallscale applications.
