Load & stability

Specify spring loaded units where shock loads & uneven track conditions exist.

Ensure sufficient load capacity:

Operating temperature

Compensate for temperature & operating environment by reducing stated load capacity.

Grraphics


Evaluate these aspects when choosing your solution:

Graphics

  • icon Orientation

    Which position does your application require the units to be mounted or function? Load ball up, down or other? Heavy duty range units operate at maximum load in all orientations.

  • Diamond Track & Contact

    What is the condition, hardness & surface finish of the material the units will be conveying or bearing against? Uneven, deformable & delicate surfaces need special consideration.

  • icon Load & Shock

    Dynamic & static load ratings are identical. Where loads are unevenly distributed or high impact/shock conditions exist, spring loaded units are ideal.

  • Temperature Speed

    Maximum conveying speeds are limited; frequency & duration may also require consideration. Dynamic & static speed ratings are identical.

  • Tools Track & Contact

    Lowest coefficient of friction & highest levels of precision movement are provided by the heavy duty ball units (pages 4 – 9). Some applications will allow a design concession to be made.

  • icon Load & Shock

    Consider the stability of the conveyed item. Ensure sufficient points of contact (pitch) to consistently support the mass. Provision for control & braking of the mass should not be overlooked.

  • Tools Environment

    Consider material upgrade options to better resist adverse environmental operating conditions. Dirty or dusty conditions? Wet & contaminated areas? Chemical attack / contamination? Magnetic permeability & radioactive fields?

  • Graphic Symbol Lubrication & Service

    Omnitrack products are lubricated for life. To further extend service life, heavy duty ball transfers & Omnifloat ranges offer additional user-service kits. Consult page 7 for heavy duty ball units & page 20 for Omnifloat glass handling casters.

  • Temperature Symbols Temperature

    Ambient temperature & maximum/minimum temperature ranges must be evaluated. Stainless steel components resist higher & lower temperatures better than standard materials (page 29).
