The REXROTH CS351S-D is a single-channel tightening controller specifically designed for fastening applications. It is part of the Compact Tightening System series from Bosch Rexroth. The controller is typically used in combination with compatible tightening spindles (such as the CS351E-D or CS351S-G) and is mainly applied to bolt fastening tasks on automated production lines.
1. Key Features
Single-Channel Design:
Unlike multi-channel controllers (such as the CS351E-D), the CS351S-D controls only one tightening channel. It is suitable for single-tool applications or standalone fastening tasks.
Compact Module:
The controller features a compact design, making it easy to install in space-constrained workstations or machinery.
Modular Compatibility:
It is commonly paired with tightening spindles such as the CS351E-D (single-channel spindle) or the CS351S-G (compact spindle), forming a complete and integrated tightening solution.
2. Application Areas
Automotive Manufacturing:
Used for bolt pre-tightening and final tightening after body welding operations.
Electronics Manufacturing:
Applied for fastening components on PCB assemblies.
Aerospace Industry:
Suitable for precision fastening of high-accuracy components.
General Industrial Assembly:
Including bolt fastening applications in home appliances, machinery, and other manufacturing sectors.
