Series 5

Radius belts are used for spiral cooling, freezing and proofing towers, safely
conveying products in food industries such as baking, meat and poultry
processing and processed food.

Design characteristics

Special features for Series 5 and 9– Suitable for straight, radius andspiral conveying– Nub Top (NTP) Surface for increased
grip and reduced contact area

– Series 5/5 ST with 45 % open area andSeries 9 with 57 % open area for excellent air circulation and drainage– Guided (G) hold down tabs allow for
full product conveyance on the belt
surface, eliminating the need for
C -profile wear strip guide rails– Stainless steel hinge pins for high load
capacity, superior radius belt pullstrength lateral stiffness, fewer belt
supports, and minimal lifting in curves– Integral end module Side Guards (SG)available in 1"/25 mm and 2"/50 mm
heights– Secure hinge pin retention in bothend modules– Very small minimum radius makes thisbelt suitable for spirals requiring smallfootprint (for drawings and details referto leaflets no. 910 and 915)

– Bearing Tab (BT) available for special
applications requiring low friction

Special features for Series 9

Special features for Series 5/5 ST– F2 through F8 end modules with integral radius expansion tabs to limit
inside belt edge collapse and productmovement across belt surface– Friction Top (FRT) center modules
available for secure product retention
and limited product movement
