The Bosch Rexroth RETURN 320+ STS (3842547533) is a sophisticated return unit designed to facilitate the efficient movement of goods in conveyor systems. This return unit boasts a VFplus feature, which significantly reduces noise emissions through its slide rails that are carefully guided within the unit. It offers flexibility in installation, allowing for the drive kit to be mounted on either the right or left side and includes a motor, coupling, and flange. The RETURN 320+ STS is equipped with a standard integrated hexagonal hollow shaft that enables the driving of parallel conveyor sections or bridges. The ball bearings are made of non-rusting steel and feature seals on both sides along with FDA-compliant grease filling, ensuring durability and compliance with food safety standards. The capability for implementing parallel sections is further enhanced by its pluggable shaft, while side elements provide mounting options for attaching holders for lateral guides or similar components. This product comes with an effective sliding rail length and an actual chain length tailored to specific requirements. Its weight is optimized for performance without compromising strength. The scope of delivery includes all necessary fastening materials, and it arrives assembled with connectors enclosed. Designed for versatility, this unit supports all track widths and chain types within certain limits of permissible tensile force. It can function as both a return unit with a maximum force of Fmax N and as a head drive without a chain bag supporting the same maximum force. Maintenance intervals may be shortened due to chain elongation considerations. The RETURN 320+ STS can accommodate conveying speeds of vN m/min, with other speeds available upon request. It's not suitable for reversible operation but excels in combination with the drive kit as a wedge conveyor drive. The Bosch Rexroth RETURN 320+ STS demonstrates an innovative approach to conveyor system drives, providing comprehensive solutions that include complete drives consisting of head drive direct configurations as well as configurable drive kits.

Return unit STS; VFplus 320

Unpacked Weight: 5.4 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
