Ball unit, recessed, steel, load bearing ball 40 mm. Supplied = assembled. Design of ball rollers = recessed. Ball diameter = 40 mm. Effective load = 225 kg. Ball material = steel (100Cr6) Housing material = sheet steel, electrolytically zinc plated. Overall height = 48.5 mm. Housing diameter = 63 mm. Max. speed = 2 m/s. Circle of holes diameter = 70.2 mm. Flange diameter = 94.6 mm. Bore hole diameter = 7 mm. Installation height = 21.2 mm. Fastening drill holes = 3. Product type = ball units. For easy movement, rotation and positioning of loads with minimal effort. Run smoothly with precise rolling characteristics. Max. conveyor speed 3 m/s. These high quality ball units are suitable for transporting products and goods which require the option of being moved horizontally to all sides and being rotated around the vertical axis. They guarantee low friction transport of materials on conveyor systems when a high load bearing capacity is required. A change of direction can be realised quick
