The Bosch Rexroth BASE UNIT 120+ AL DIRECT (3842546122) is a versatile and efficient base unit designed for conveyor systems, featuring a direct drive kit that allows for the quick transformation into a head drive with variable mounting positions. This product is engineered to reduce noise emissions through the use of slide rails guided in the head drive, enhancing the operational environment. The unit can be installed on either side with options for right or left motor, coupling, and flange configurations. The integrated double-sided hexagonal hollow shaft enables the drive of a parallel conveyor section or bridge, facilitating synchronous operations and allowing for easy connection to other components. The BASE UNIT 120+ AL DIRECT supports all track widths and chain types, with a maximum permissible chain tensile force and adjustable section lengths to accommodate various applications. It has been designed for non-reversible operation and includes a chain bag to compensate for elongation over its service life. Constructed from die-cast aluminum with a powder-coated silver finish, this base unit ensures durability and resistance to corrosion. The chain wheel and guide are made of PA material while the ball bearings are crafted from non-rusting steel with FDA-compliant grease filling, ensuring high standards of hygiene for industries requiring such compliance. The hexagonal shaft is made from PA up to a certain size, beyond which non-rusting steel is used. Furthermore, the side elements come equipped with slots for attaching holders for lateral guides or similar accessories. For inclined sections, it is recommended to use a chain sprocket to prevent backslipping of the chain. The scope of delivery includes fastening materials with assembled chain guards enclosed. While active or passive bridge connection kits and synchronous drive connection kits serve as recommended accessories, additional components such as drive kits and motor support are required to complete installation and functionality. Overall, the Bosch Rexroth BASE UNIT 120+ AL DIRECT stands out as an innovative conveyor component offering flexibility in application while maintaining high performance in material handling tasks.

BASE UNIT 120+ AL DIRECT

Base unit AL, VFplus 120 dir.

Unpacked Weight: 4.07 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 Implementation of parallel sections with gap dimension down to zero Side elements with slot to attach holders for lateral guides, or similar A chain sprocket must be used to limit the chain slipping back on inclined sections.

The base unit is quickly turned into a head drive with variable mounting position by adding a drive kit.

With the double-sided hexagonal hollow shaft, other components can be easily driven using a transmission (active bridge).

Size: all track widths Suitable chain types: all Permissible chain tensile force: Fmax = 1250 N Section length: L ≤ 30 m Conveying speed: vN 4-27 m/min, other speeds available on request Chain bag to compensate for chain elongation during service life Not suitable for reversible operation
