Description: Chakra range of flexible drive couplings are manufactured that could be used for positive transmission of power from one shaft to another. Chakra couplings consist of two gear hubs engaged in a sleeve of high grade plastic material. This material is of superior strength and wide operating temperature range. The gears have crowned tooth form, which permits axial and angular misalignment. The couplings are easy to assemble and require no maintenance or lubrication and generate no transmission raise. These find application in all ranges of hydraulic equipment and in the transmission market and is maintenance free. Features include no lubrication. Crowned teeth form gears permitting axial and angular misalignment. Regarding features it is cost effective and easy to assemble; compact and streamlined.
