The Bosch Rexroth RETURN 120+ AL (3842547518) is a sophisticated return unit featuring an AL construction, designed to provide a reduced noise emission due to its slide rails guided within the unit. It offers the flexibility of installing the drive kit on either side—right or left—accommodating motor, coupling, and flange. This versatility extends to driving a parallel conveyor section or bridge with an integrated standard hexagonal hollow shaft. Crafted with durability in mind, the RETURN 120+ AL boasts ball bearings made from non-rusting steel, sealed on both sides and filled with FDA-compliant grease, ensuring reliable operation in various environments. The side elements include slots for attaching holders for lateral guides or similar components, enhancing the unit's adaptability. The material composition is robust and hygienic; housing is made from die-cast aluminum that's powder-coated for extra protection, while chain wheels and guides are constructed from PA. For larger sizes, the hexagonal shaft is made from non-rusting steel, ensuring longevity and compliance with stringent standards. This return unit is capable of supporting all track widths and chain types while withstanding a permissible chain tensile force. It can function as a return unit with a maximum section length of m or as a head drive without a chain bag for lengths up to m. The conveying speed stands at vN m/min, offering efficiency in operations. Additional features include its capability as a wedge conveyor drive when used with the drive kit but it’s not suitable for reversible operation. The design allows for high flexibility and short delivery times due to its innovative concept and standardized components. With stainless steel ball bearings sealed on both sides filled with FDA-compliant grease and implementation options for parallel sections down to zero gap dimension, this unit exemplifies efficiency combined with adaptability. In summary, the Bosch Rexroth RETURN 120+ AL return unit is fully assembled upon delivery and includes all necessary fastening material. It represents an advanced solution for conveyor systems requiring reliable returns or drives functionality within their operations.

Return unit AL; VFplus 120

Unpacked Weight: 1.95 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
