The Bosch Rexroth BASE UNIT 90+ CENTER (3842552941) is a versatile and robust center drive basic unit designed to integrate seamlessly into conveyor systems where space is at a premium at either end of the conveyor section. This unit can be easily converted into a fully functional center drive by adding the provided drive kit, making it adaptable for various industrial applications. The BASE UNIT 90+ CENTER features a reduced noise emission due to its slide rails that are guided in the head drive. The installation of the drive kit is flexible, allowing for motor mounting on either the right or left side. The unit includes a hexagonal hollow shaft as standard, which facilitates the driving of parallel conveyor sections or bridges. It boasts stainless steel ball bearings with seals on both sides and FDA-compliant grease filling, ensuring durability and compliance with strict hygiene standards. The side elements come with slots for attaching holders for lateral guides or similar components, enhancing its adaptability. With an effective sliding rail length and actual chain length that varies per specific application requirements, this base unit has been engineered to support a maximum chain tensile force of Fmax N and can handle conveying lengths up to m. It operates with a chain return on the underside of the profile and offers conveying speeds of vN m/min, with other speeds available upon request. Users are advised that since there's no length compensation chain bag present, regular checks and adjustments to the chain length may be necessary. The scope of delivery includes all necessary fastening materials and comes assembled, with a profile connector enclosed for ease of installation. The construction materials include non-rusting steel for housing and connectors, PA for chain wheel and guide, further ensuring longevity and reliability in various operational environments. An assembly module is required when assembling the chain onto this BASE UNIT 90+ CENTER by Bosch Rexroth.

BASE UNIT 90+ CENTER

Basic unit center drive VFplus 90

Unpacked Weight: 4.28 kg

Drive of a parallel conveyor section or bridge using a hexagonal hollow shaft integrated as standard Stainless steel ball bearings, with sealing on both sides and FDA-compliant grease filling Side elements with slot to attach holders for lateral guides, or similar

The center drive basic unit is used if the available space is limited at the ends of the sections. It is quickly turned into a center drive with variable motor mounting position by adding the drive kit

Size: 65-120 Chain return on the underside of the profile Conveying speed: vN = 2 ... 60 m/min, other speeds available on request Permissible chain tensile force: Fmax = 600 N Max. conveying length: 7 m Because no length compensation (chain bag) is present, the chain length must be checked regularly and shortened if necessary Recommendation: No accumulation up to 1000 mm after the return unit An assembly module is required for assembling the chain
