Light-duty castors - Import export

Light-duty ball transfer units are assembled from pressed sheet steel components, except for the LP series which are machine turned from an acetal solid bar. All light-duty ball transfer unit designs feature a hemispherical cup for the recirculation of the small supporting balls. This allows a smooth rotation of the protruding, load-bearing ball. All light-duty ball transfer units (except LP) feature a heat-treated support cup which is resistant to wear.

Our Medium Duty ball transfer units are machined from solid steel bar which is heat-treated to provide a hemispherical wear-resistant chamber within which the recirculating balls can support the protruding, load-bearing main ball. This robust, low-noise design is engineered for applications requiring conventional (ball ‘up’) orientation. Additional options for this range include impact-absorbing top cap options, and additional drain channels where required, making these transfer units the air cargo industry standard.

Innovative patented design incorporates a hardened and precise ground internal support component. The heavy duty design allows the internal recirculating balls to form an endless track/race to allow the full load to be applied at any angle of inclination. Compact design allows much higher load capacity than the comparable ‘cup & ball’ hemispherical chamber design used in both Omnitrack medium duty and light duty ranges.
