1.0:1 Turn Ratio. Small Radius Omni-Flex® conveyor belts can negotiate a much tighter turn than regular Omni-Flex belts. 

Small Radius Omni-Flex®

In general, the inside radius can be equal to the belt width, making Small Radius Omni-Flex ideal for use in applications where floor space is limited. Small Radius Omni-Flex can turn either left or right (only), pivoting about a center link.

Superior Strength & Load Capacity for High Speed, High Tension Spiral and Turn-Curve Applications

Superior Strength & Load Capacity for High Speed, High Tension Spiral and Turn-Curve Applications

Ashworth Omni-Flex® belts are the original turn-curve conveyor belts and have been delivering reliable performance since 1959.

These flat wire belts are constructed with heavy duty, precision formed rod ends for extended cage life and button heads for maximum strength and reduced wear. Unlike straight-running flat wire belts, Omni-Flex® belts are constructed with slots instead of holes. The slotted design allows the belt to collapse on either side, for both left-hand and right-hand turns.

Stainless Steel, Heavy Duty Construction

All Omni-Flex® components are precision crafted from premium quality stainless steel to exacting standards. The finish is smooth and burr-free for easy clean-up and excellent sanitary properties. Two rows of reinforcing bar links are standard to provide strength.

Broad Range of Sizes & Accessories

Available flat wire mesh dimensions for Omni-Flex® belts include 1" x 1", 1/2" x 1" and 1/3" x 1". Ashworth patented fatigue-resistant pickets are available on most Omni-Flex® belts and increase belt service life by about 30%. Other accessories such as guard edges, reinforcing bar links, and lane dividers are available for special needs.

Guard Edges

Plates assembled onto belt edges to prevent product from falling off. Guard edges serve to replace bar links on a one-to-one basis. Available heights (above the conveying surface) are: 0.50" (12.7 mm), 0.75" (19.1 mm), 1" (25.4 mm), 1.5" (38.1 mm), and 2" (50.8 mm).

Lane Dividers

Detachable or non-detachable plates assembled into the belt’s surface to locate product. Available heights (above the conveying surface) are: 0.50" (12.7 mm), 0.75" (19.1 mm), 1" (25.4 mm), 1.5" (38.1 mm), and 2" (50.8 mm). The maximum number of lane dividers = Belt Width / 9" (228.6 mm).

Fatigue Resistant Pickets (Patented)

These special pickets, which are manufactured with an outward facing radius centered on the trailing face of the picket, are designed to extend the service life of the belt by approximately 30%. This radius serves to lengthen the belt pitch in selected openings near the outside edge of the belt. This causes the bar links to bear the full load of the belt in a turn, relieving stress on the picket, which increases the belt’s service life.
