Streamlined Wire & Cable Assembly: Beaded Systems Now on Chamfr
Strand Products Joins Chamfr
Chamfr’s latest additions bring fresh innovation to wire and cable assemblies with two precision-engineered systems from Strand Products: the Beaded Wire System (BWS®) and Beaded Strand System (BSS®). These systems, available in stainless steel, nitinol, and tungsten, offer plug-and-play simplicity for engineers designing everything from steerable catheters to robotic arms—without the need for secondary hardware or terminal machining.
Both product lines use a proprietary process to create spherical beads at the end of solid wires or stranded cables, forming secure mechanical stops directly from the source material. The result? Fewer parts, less friction, and more streamlined builds.
Beaded Wire System (BWS®)
Strand Product’s Beaded Wire System® (BWS®) includes solid wire and tube-based assemblies made from stainless steel and nitinol. Each features a precisely formed bead, built to hold tolerances while eliminating the need for external anchors or connectors.
Key specs include:
- Materials: 304 Stainless Steel, Nitinol
- Diameters: 0.015″–0.042″
- Lengths: 60″
- Bead sizes: 0.030″–0.060″ (±0.010″)
Use cases: steerable shafts, catheter tips, guidewire terminations, and fluoroscopic tools where low profile, repeatable performance matters.
Beaded Strand System (BSS®)
For more flexibility and tensile strength, the Beaded Strand System® (BSS®) line features stranded stainless steel, nitinol, and tungsten cables with integrated spherical terminations.
Key specs include:
- Materials: 304 Stainless Steel, Nitinol, Tungsten
- Constructions: 1×7, 1×19, 7×7, 7×37, 8×19
- Diameters: 0.006″–0.027″
- Lengths: 12″ or 60″
- Bead sizes: 0.010″–0.050″ (±0.010″)
Ideal for: angioplasty guidewires, prosthetic linkages, robotic tools, and endoscopic systems where reliability, radiopacity, or compact geometry are critical.
Bonus Additions for Prototyping & Integration
Beyond the core BWS® and BSS® SKUs, Strand Products is also bringing three useful additions to Chamfr:
- Preassembled Subassembly (SUTP-006-NITI-01): Combines a shape-set nitinol loop and hypodermic hypotube—great for catheter shaft prototypes and retrieval tools
- Plated Brass Grip (SG1): Threaded accessory for securing BWS®/BSS® components in test setups or device prototypes. Fits wire diameters from 0.015″–0.040″
- R&D Sample Pack featuring the Beaded Wire System®, Beaded Strand System®, and Advanced Mechanical Assemblies
Precision Meets Practicality
All components are processed in ISO Class 7 cleanroom conditions and feature:
- Beads formed from the base material for seamless biocompatibility
- Surface finish of 63 µin
- Labeling with lot #, part #, and tolerances for medical-grade traceability
- Optional passivation and ultrasonic cleaning available
Whether you’re streamlining a catheter tip, prototyping a robotic joint, or building out test rigs, Strand Products’ new offerings make it easier to achieve high-performance, low-profile terminations with less rework and fewer parts.
