The Bosch Rexroth RETURN 90+ STS (3842547529) is a versatile and efficient conveyor return unit designed for seamless integration into various material handling systems. This unit features a reduced noise emission due to its slide rails guided in the return unit, enhancing the working environment. It is engineered to allow installation of the drive kit on either the right or left side, providing flexibility in motor, coupling, and flange placement. The RETURN 90+ STS is equipped with a hexagonal hollow shaft as a standard feature, enabling the drive of parallel conveyor sections or bridges. The ball bearings are made from non-rusting steel and come with seals on both sides along with FDA-compliant grease filling, ensuring durability and compliance with stringent hygiene standards. The side elements of this return unit include mounting options for attaching holders for lateral guides or similar components, broadening its application scope. This product's material information highlights chain wheels and guides made from PA material, while larger hexagonal shafts are constructed from non-rusting steel. It also includes non-rusting steel housing and connectors for added robustness. The RETURN 90+ STS can support all track widths and is compatible with all chain types. It is capable of handling a maximum chain tensile force of Fmax N in its return unit function and Fmax N when operated as a head drive without a chain bag. With an effective sliding rail length tailored to specific requirements, the RETURN 90+ STS can accommodate section lengths up to L m for its return function and L m when functioning as a drive. It offers conveying speeds of vN m/min, with other speeds available upon request. Notably suitable for use as a wedge conveyor drive when used in combination with the drive kit, it is not designed for reversible operation. The Bosch Rexroth RETURN 90+ STS comes assembled with fastening materials included, offering ease of installation through its complete drives that consist of head drives direct and configurable drive kits. Its innovative design simplifies multitrack system implementation while ensuring reliable operation across various applications.

Return unit STS; VFplus 90

Unpacked Weight: 2.84 kg

Thanks to the innovative drive concept, the return unit can be operated simply by itself or supplemented with a drive kit to be operated as a head drive without chain bag. The section length is limited to a maximum of 7 m.

Size: all track widths Suitable chain types: all Permissible chain tensile force

Return unit function: Fmax = 1250 N

Head drive function without chain bag: Fmax = 600 N

With shortened maintenance interval, due to chain elongation

Section length for return unit function: L ≤ 30 m

Section length for drive function: L ≤ 7 m

Conveying speed: vN = 2-60 m/min, other speeds available on request Use in combination with the drive kit as a wedge conveyor drive Not suitable for reversible operation

The standard drives are easy to couple and enable straightforward implementation of multi-track systems
