The Bosch Rexroth RETURN 90+ AL (3842547517) is a versatile and advanced return unit designed for conveyor systems. This unit is characterized by its reduced noise emissions, which are achieved through slide rails that are meticulously guided within the return apparatus. It is engineered to allow for the installation of a drive kit on either the right or left side, including a motor, coupling, and flange. The RETURN 90+ AL also facilitates the drive of a parallel conveyor section or bridge via an integrated standard hexagonal hollow shaft. Constructed with high-quality materials, the housing of this unit is made from die-cast aluminum with a durable powder coat finish. The chain wheel and guide are crafted from PA (polyamide), while the ball bearings are made from non-rusting steel 1.4301, complete with seals on both sides and FDA-compliant grease filling for reliable performance in various environments. These ball bearings ensure smooth operation and longevity of the system. The RETURN 90+ AL is designed to cater to all track widths and is compatible with all types of chains that the system might employ. It can handle maximum permissible chain tensile forces efficiently in both return unit function (Fmax = N) and head drive function without chain bag (Fmax = N). The innovative design allows for conveying speeds up to vN = m/min, with customization options available upon request. This product also boasts high flexibility and rapid delivery times due to its standardized components that facilitate easy stock-keeping. Additionally, it includes side elements with slots designed for attaching holders for lateral guides or similar accessories. The Bosch Rexroth RETURN 90+ AL comes fully assembled including all necessary fastening materials, ensuring ease of installation. Its implementation allows for seamless integration into existing conveyor systems or as part of new installations where efficiency, reliability, and low maintenance are key operational requirements.
