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.

Industry applications
For the most demanding bottling and container applications, there is no substitute for the performance and productivity of Rexnord TableTop and MatTop Chains. Since 1938, with the ground-breaking 815 TableTop stainless steel straight-running chain, Rexnord has pioneered innovation in beverage and food conveying that has inspired loyalty and driven specification for Rexnord conveyor chains from customers around the globe.
Line efficiency
Smooth container flow at high speeds is essential to increase line efficiency and preventing product damage. Especially when moving from multiple to single lanes or the reverse, the gentle slide of bottles across ultra-flat, highly polished stainless steel Rexnord chain can contribute significantly to the quality and efficiency of your beverage production line.
Applications in beverage
Rexnord products cover a wide variety of applications like: general conveying of glass bottles one-way and return, PET bottles and other plastic containers, jars, cans 2- and 3-piece, crates, plastic containers, boxes, shrink-wrapped packages.
Product Portfolio
Rexnord offers a comprehensive of conveyor products which include
Metal TableTop chain
Plastic TableTop chain including LBP and Supergrip
Plastic MatTop chain in standard, small pitch and heavy duty alternatives.
Magnetflex Corner tracks as well as alternatives like Tab and Bevel curves
Machined and moulded sprockets
High performance polymer materials & economic alternatives for less demanding applications
Pack and case conveying that offers flexibility of line configurations and total system cost efficiencies can significantly improve productivity at the dry end of filling lines. At the same time, brand extensions, innovative packaging, and light weight packaging materials are driving more demanding performance in pack and case handling. Cases and packs must be protected from damage even as they move rapidly out of case packers and shrink wrap machines and into, around, and out of curves.
That’s why Rexnord’s case and package handling conveying chains come in our modular small pitch, lightduty 15mm 1500 Series to medium duty 25.4mm pitch 1000 Series to the heavy-duty 1 in pitch 1005 Series in both versions for general conveying and in Super Grip / RubberTop™ versions for metering, incline, decline and braking applications. Furthermore the programm includes a comprehensive portfolio of Sideflexing MatTop chains like the versatile 1200-series MatTop. For accumulating conveyor the LBP (Low Backline Pressure) chains offers a solution to a large variety of applications.
With the Rexnord original Heavy Duty TableTop chains for packaging conveying, no other company provides the breadth of conveying solutions for your case and package handling requirements.
Rexnord products are known for their reliable performance in though conditions and challenging applications due to their robustness in design and drive technology. In container making therefore Rexnord products are often the preferred choice for applications like vacuum elevators, high speed (magnetic) conveyors, UV applications, high temperature applications and inspection conveyors.
Rexnord Material innovation
On top Rexnord offers the most comprehensive material portfolio in the market to meet an extensive variety of application requirements. Several applications in glassworks and container making lines combine an abrasive environment with the need for smooth container handling. Often these applications can not be easily lubricated to neutralize the effect of the hard abrasive particles in the environment. Therefore specialized materials can be part of a custom made solution. This is why, besides several proven specialized high performance materials like WX, HP and PS, Rexnords material portfolio is now completed with DKA aramid reinforced material.
Processing and packaging food faster with a lower life-cycle cost, less downtime, and reduced product waste requires people, technology, and processes working together to make plant efficiency and productivity the number one goal.
Conveying technology in this respect is a vital part in every food processing plant. As conveying chain and components come into direct contact with food during processing, they strongly contribute to plant process hygiene. Easy-to-clean conveying chain, based on sound hygienic design, contributes to better food safety while at the same time reducing costs through more effective cleaning. Further the reliability and robustness of the chain strongly contribute to the up time of the processing line.
Rexnord food conveying chain technology and food-safe material innovations offer high productivity solutions for food applications throughout each food manufacturing plant. That is why Rexnord’s 510, 1010, 1200 and 2010 Series MatTop® Chain, with their foodgrade design and easy-to-clean features, can be an important part of a robust and effective food safety program in every food processing plant.
Rexnord’s automotive solutions build on more than 100 years of conveying technology experience across multiple industries. From the mechanical press to the final inspection conveyors, Rexnord has developed low maintenance modular chain solutions for your applications. By assessing your individual needs and objectives, Rexnord’s skilled engineers will help you obtain the lowest Total Cost of Ownership (TCO), resulting in significant cost savings by improving operational safety, efficiency and productivity.
Rexnord 6990 Series Hybrid MatTop Chain
The 6990 Series Hybrid MatTop Chain (patent pending) is designed for automotive conveyors with high loads or frequent load variations (people movers). The steel structure in the chain creates stiffness and strength enabling the chain to be used in conveyors with lengths over 328-feet (100m) (moving people, vehicles or a combination of the two).
Rexnord 3120 Series MatTop Chain
The 3120 Series MatTop Chain is primarily used for industrial type applications: car washes, skid handling, people movers, pallet handling, and automotive parts handling. The sturdy design is molded in high-strength acetal material and utilizes Rexnord’s Twistlock pin retention system.
Rexnord 3180 Series MatTop Chain
Rexnord recognizes the importance of opportunities to easily and economically convert from existing technology in skid applications and has developed the 3180 Series MatTop Chain. These chains are suitable for 3.2 inch (81mm) skid conveyors, allowing the skids to be aligned mechanically before transferring to the next conveyor.
Successful processing in tunnel pasteurizers, warmers and coolers requires highly reliable, controlled conveying through the tunnel pasteurizer, and smooth container transfers at the infeed and outfeed. To have the highest conveying chain reliability, to eliminate product waste from tipped or broken containers, and to achieve durable conveying performance, Rexnord’s 2000-series USP MatTop chain and the Rexnord’s 9200 series Fortrex Stainless Steel MatTop Chain are specifically designed for superior performance in the demanding environment of pasteurizers, warmers and coolers.
DTS-C Dynamic In- and Outfeed Transfer
DTS-C patented by Rexnord combines special transfer combs and in/outfeed chains to the main Rexnord Pasteurizer belt for full self clearing transfers. This eliminates the dead plate area and ensures a continuous product flow eliminating back line pressure and potential product damage.
USP Ultra Stabilized Polypropylene Material
USP material is a unique formulation of stabilizers and anti-oxidants which protects the chain’s polypropylene material from degradation due to heat and/or chemicals. The USP material increases the reliability throughout the chain life cycle and helps to avoid the risk of unscheduled downtime.
PosiTrack centre guides
Patented integrated center guiding lugs ensure optimum chain tracking and keeps the chain sides from touching the tunnel structure, and eliminates the need to lock sprockets on the shaft.
