THE sole distributor of Bosch Rexroth products in sub-Saharan Africa, Tectra Automation, has announced the addition of Rexroth inverted-tooth chains to its product line. Modern-day machinery production demands that drives be cost-effective, precise and reliable. The Rexroth inverted-tooth chain meets these requirements owing to its unique two-part rolling pivot joint and specially meshed inverted-tooth chain and sprocket. The inverted-tooth chain is suitable for use in a wide range of conveying applications, including heavy-duty and robust operations, conveying parts with small or large dimensions, processed or unpro-cessed work pieces, and fragile items. The inverted-tooth chains are used for classic circuit operation and, owing to their technical advantages, are ideal for drives with shafts that run in counter rotation or for reverse-operation drives.

The chains can also be used as couplings. The Rexroth inverted-tooth chain drive solution is distinguished by extremely smooth, quiet and precise running. Wear is evenly distributed over all joints and pitches are increased at the same rate. Consequently, all links scribe one common pitch circle. The interlocking power transmission between the chain and sprocket is slip-free and no pretensioning is necessary. The variable construction of the inverted-tooth chains allows for any width or length. This is of significance when used in cramped spaces.
