Rexnord 6990 Series
Hybrid MatTop Chain
High load capacity
High load distribution up to 50,000 N/m with standard
polypropylene pins, over 70,000 N/m with PBT Pins.
Raised performance level for high loads, frequent load variation(people movers).
Load distribution over
....
N/m through steel tensions plates and steel pins.
Higher chain stiffness
Robust design with equally divided hinge eyes.
Integrated steel structure that creates high stiffness and strength. Smooth
running chain eliminating slip-stick or pulsation. Realizing conveyors over 656 ft
(200m) in applications moving people, vehicles or combinations.
Long life chain design
Large pin diameter. Optimized hinge eye width and
proven wear resistant design of the chain underside.
Steel pin and wear plates guarantee extreme wear resistance.
Easy installation and
maintenance
Twist-Lock
pin retention clips prevent the loss of

The 6990-Series 2¼-inch pitch heavy-duty MatTop chain is designed for the automotive industry, to be used in long and wide
conveyors, without the requirement for tensioning. The 6990 technology is suitable for minimizing the overall conveyor height
construction avoiding deep pit constructions. The high load capability of these belts allow the handling of people and cars
in assembly lines, water and leak testing and car wash applications. The 6990-series is available in full plastic and in the so
called hybrid versions which raise the performance level of plastic modular chains. Conveyors with lengths up to 656 ft (200m)
and beyond are realized. The belts are standard supplied in high-performance Acetal with a closed surface or with a (non-skid)
safety top surface.
Features
•
High Load capacity up to 50,000 N/m with standard pins and over 70,000 N/M with PBT Pins.
