Compact 25 mm Ball Casters for Smooth Multidirectional Movement Key benefits Small footprint for tight spaces: 25 mm diameter fits compact projects where larger casters cannot be used. Lightweight and low drag: At 0.11 pounds each, these ball casters add minimal weight while providing smooth rolling motion. Clear visual coding: Color designation 4upper4down helps with quick identification and organization during installation or inventory. Versatile movement: Designed to enable easy omnidirectional motion, reducing friction and wear on sliding or rotating parts. Simple integration: Suited for a wide range of applications that require a compact caster solution. Important attributes Size: 25 mm diameter for compact applications Color: 4upper4down for identification and matching Item weight: 0.11 pounds per caster Function: Provides multidirectional rolling support to improve mobility and reduce surface abrasion Compatibility: Intended for projects and equipment that accept 25 mm ball casters or require a small, lowprofile rolling element Practical use scenarios Small furniture and cabinets: Add mobility to lightweight stands, display cabinets, or movable shelves where space is limited. Robotics and electronics platforms: Provide smooth, lowfriction movement for small robots, sensor mounts, or mobile prototype platforms. Retail displays and craft projects: Enable easy repositioning of display pieces, model setups, and DIY furniture without bulk. Why choose these casters Precise size and weight make them a predictable, easytospec component for compact designs. Color coding helps reduce installation errors when multiple caster positions must be matched. Their omnidirectional rolling action improves maneuverability for small mobile items and prototypes. What to consider before buying Confirm that a 25 mm diameter caster matches your mounting or cavity dimensions. Verify the required number of casters and load distribution for your application, given the lightweight nature of each unit.
