Industrial component specialists Elesa have extended their portfolio with a high quality range of ball transfer units - ref GN509. Designed specifically for movement of workpieces or sub-assemblies or for ease of positional adjustment GN509 ball transfer units fit into any conveyor system to facilitate linear or rotary movement of heavy loads such as sheet steel, pallets, work jigs etc, either under gravity or manual control.
GN509 units are modular push fit ball assemblies featuring a large centre load contact ball with a 'nest' of smaller friction reducing balls in a hemi-spherical cup. Application is generally in a matrix format which ensures that at least 3 ball units are in contact with the load at any time in both x and y axis - thus ensuring good stability and load carrying capacity at conveying speeds of up to 2m/sec.
GN509 units are available in 12mm to 60mm ball sizes with static load capacities up to 13000N. Fitment is by simple drop in location and spring retainer rings are available to more easily facilitate removal. Further information on Elesa (UK) Ltd products may be found at: www.elesa.co.uk
