Medium Duty ball transfer units are machined from solid steel & case hardened for wear resistance. Reinforced machined steel top cap protect against impact from misalignment of the conveyed item. Lubricated for life & zinc plated for resistance to corrosion. Standard materials; Body & cap AISI 1015, Balls AISI 52100. Stainless steel upgrade ‘A’ & ‘SS’ feature AISI420 balls Shock Resistance & body. Main ball sizes ≥19mm incorporate a felt seal to restrict contamination.

This series features a single drain hole.

Air Cargo Ball Units – Compliant with ISO Air cargo industry standards these units utilise stainless steel (AISI 420) balls recirculating within a precision machined Steel (AISI 1015) housing. All models feature fluid drain & omit felt seal. Consult page 11 for C-type (stainless steel) & K-type (spring steel) optional fixing clips.

MV ‘Imperial’ Series – Integral moulded scraper cap reduces weight & noise levels during operation. Compact inch series dimensions ideal for high-density ball cargo decks.

MX ‘Cargo’ Series – Steel scraper cap protects against impact damage from misaligned loads. Multiple debris/drain channels rapidly eject contamination & fluid.

MW ‘Washdown’ Series – Internal stainless steel liner cup provides a cost efficient alternative to all stainless steel construction. Effective corrosion resistance & fluid draining in washdown applications. Also available in all stainless steel.
