The Bosch Rexroth BASE UNIT 90+ AL DIRECT (3842546121) is a versatile conveyor base unit featuring a direct drive kit that transforms it into a head drive with flexible mounting options. This base unit is designed for quiet operation, thanks to its reduced noise emission and the use of slide rails guided in the head drive. It facilitates easy installation of the drive kit, which can be positioned on either side, and includes a motor, coupling, and flange. The integrated double-sided hexagonal hollow shaft allows for the driving of parallel conveyor sections or bridges, enhancing the unit's adaptability in various configurations. The base unit supports all track widths and chain types, with a maximum permissible chain tensile force of N and section lengths up to m. It offers a standard conveying speed of m/min, with other speeds available upon request. Equipped with stainless steel ball bearings that are sealed on both sides and filled with FDA-compliant grease, this base unit ensures durability and hygiene for food-related applications. The implementation of parallel sections is seamless, even with zero gap dimensions. Additionally, side elements feature slots for attaching holders for lateral guides or similar accessories. For inclined sections where chain slippage might be a concern, the use of a chain sprocket is recommended to prevent backward slipping of the chain. The housing is made from die-cast aluminum that's powder-coated in silver for durability, while other components like the chain wheel and guide are constructed from PA (polyamide). The hexagonal shaft is also made from non-rusting steel for sizes beyond , ensuring longevity. This product comes assembled with included fastening material and enclosed chain guards. While active or passive bridge connection kits are recommended accessories, drive kits and slide rails are required for full functionality. Bosch Rexroth has ensured that this base unit meets stringent requirements while offering flexibility in design and application.

BASE UNIT 90+ AL DIRECT

Base unit AL, VFplus 90 dir.

Unpacked Weight: 4.01 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
