The Bosch Rexroth RETURN 90+ 90° (3842552985) is a return unit designed for building alpine conveyors with the chain running exclusively on the upper side. This innovative return unit boasts several advantages over traditional alpine conveyors with head drives. Firstly, it features a shorter chain return, which reduces the tensile force needed for the conveyor chain, allowing for a larger volume within the alpine conveyor system. Additionally, there is no need to mount slide rails for chain return on the underside of the profile, streamlining installation and maintenance processes. The RETURN 90+ 90° is optimized for use with connection drives AL and STS as well as curve wheel drive kits parameterized as AC. It supports a maximum section length for the return unit of Lmax meters and can handle a maximum chain tensile force of up to N for drive purposes. The material specifications include nonrusting steel for both housing and connectors, PA (polyamide) for chain wheel, chain guide, and hexagonal shaft, ensuring durability and compliance with FDA standards where necessary. This return unit comes fully assembled, including fastening materials suitable for AL systems such as an adapter ALSTS. The effective sliding rail length x actual chain length ratio and weight are carefully calibrated to enhance performance while maintaining structural integrity. The scope of delivery includes all necessary components to ensure a quick setup without additional procurement. The Bosch Rexroth RETURN 90+ 90° (3842552985) represents an efficient solution for constructing alpine conveyors that require less maintenance due to its shorter conveyor chains and eliminates the need for additional slide rails beneath the profile—overall providing an improved design over conventional systems.

RETURN 90+ 90°

Return unit 90°; VFplus 90

Unpacked Weight: 3.7 kg

Advantage over alpine conveyor with head drive:

- Shorter chain return, so the required tensile force of the conveyor chain is lower and therefore the possible volume of the alpine conveyor is larger
- No longer necessary to mount the slide rails required for the chain return on the bottom side of the profile
- The required conveyor chain is shorter

For building alpine conveyors with chain running only on the upper side.

Only for use with:

- Connection drive (AL and STS)

- Drive kit, curve wheel AL (parameter AC = 1)

Size: 65, 90 Section length for return unit: Lmax = 30 m Chain tensile force for drive: max. 600 N Alpine conveyor for curve wheel drive or connection drive
