There are several key considerations that you need to consider when selecting the correct Omnitrack Ball Transfer Unit or Movement Solution for your Omni-Directional application.
1. Will the application use the units in the ‘Ball up’ or ‘Ball down’ position?
If it is ‘Ball down’, you should consider using a High Capacity Unit due to the specially designed ‘double recirculation’ interior mechanism which provides maximum precision and smoothest performance at any angle of orientation without any loss in load bearing capabilities.
2. What is the maximum load of the item you intend to convey?
Is this weight distributed evenly across the entire object? If uneven or shock loads are a concern, you should carefully consider the layout of the units and also consider the use of spring loaded units to ensure that the load is fully supported at all times.
3. What are the maximum and minimum dimensions of the item you intend to convey?
With ‘Ball up’ applications, the smallest dimension divided by 3.5 will determine the spacing of the units. This will ensure that the thinnest profile of the item you intend to convey will always meet a minimum of 3 units during movement.
4. What is the material that the Ball Units will be in contact with?
Standard ball materials are AISI 52100 Chrome Steel which is hardened to around 60 Rockwell ‘C’ and will therefore mark / damage relatively softer materials (such as wood, plastic and even aluminium). You should consider using either hardened steel or cold rolled steel track as the contact material for the Ball Transfer Units, upgrading the Ball Material to a ‘non marking’ option or use a sacrificial material between the running surface and Ball Transfer Units which can be replaced easily.
5. How fast will the Ball Transfer Units have to rotate?
Every range of Ball Transfer Unit and Movement Solution has a speed rating and you should ensure that the unit you choose is suitable for the speed of your application.
6. What type of fixing option do you require?
Choose from Plain Fitting, Flange Mounted, Socket Mounted, Threaded Stud, Tolerance Rings…view the full range at http://www.omnitrack.co.uk
7. What are the environmental conditions that the Ball Transfer Units have to work in?
Are the units likely to come into contact with water, dirt, debris etc? At what temperature do the units have to operate or be subjected to? Consider material upgrades to suit the potential risk of corrosion present in the application.
