Prevent Component Loss and Ensure Machine Compliance

Elesa offers a comprehensive range of retained clamping elements and securing accessories designed to prevent the loss of critical machine components, reduce maintenance downtime, and ensure compliance with international safety standards, including the Machinery Directive 2006/42/EC.

Secure Clamping Under Stress

One of the most common retention solutions involves the use of threaded inserts with locking mechanisms that keep handwheels and knobs firmly in place—even under vibration or mechanical shock. Elesa's offering includes:

BT-HP and BT-HP-AV: Retained fluted knobs

GN 653.2: Retained screws with knurled knobs

VCT-RC and VTT-RC: Lobe clamping knobs or handwheels with retaining ring, offered without a pre-attached chain to allow complete customization of chain type and length.

Retaining Chains and Cables for Loss Prevention

Elesa offers various technopolymer, metal, and hybrid chain/cable solutions to support a wide range of assembly needs. These can be used to attach knobs, handwheels, pins, and other components directly to the machine body.

CT-S Series – Technopolymer and Stainless-Steel Ball Chains

These flexible retention solutions pair well with ball pins and locking pins:

CT-S: Chain without rings
CT-S-A: Chain with one ring
CT-S-2A: Chain with two rings

CV-T Series – Polyethylene Retaining Cables

Made from high molecular weight polyethylene (HMWPE) and stainless steel, these lightweight yet durable cables are optimized for ball pin applications:

CV-T: Cable without plate or ring

CV-T-P: Cable with one plate

CV-T-A-P: Cable with one ring and one plate

CV-T-2P: Cable with two plates

CV-T-2A: Cable with two rings

GN 111 Series – Stainless Steel and Brass Retaining Chains

Elesa also offers a robust line of stainless-steel retention chains, including:

GN 111: Brass and stainless-steel ball chains

GN 111.2: Stainless steel cables with optional PVC coating (black or transparent)

GN 111.8: Stainless steel retaining cables in multiple types (A & B) with equal or stepped ring diameters, suitable for use with ball pins and axially locked centering pins

GN 111.4 – Spiral Retaining Cable

This version combines stainless steel with a polyurethane spiral sheath, offering high flexibility and strong retention performance for dynamic applications.

GN 111.6 – Retaining Rings

Designed for use with cranks and rotating components, these stainless-steel rings mount via a groove and can be paired with additional retaining cables like GN 111 or GN 111.2 to prevent loss

Compatible Components and Applications

These retention solutions integrate seamlessly with Elesa's range of indexing plungers, ball pins, spring plungers, and self-locking studs:

GN 124

GN 113.1

GN 113.8

GN 114.2

GN 114.6

Various sizes and material executions are available to suit different application environments, including those exposed to corrosion, vibration, or high mechanical stress.

Why It Matters

Component loss in machines not only disrupts operations but can also pose significant safety risks. Elesa's retained clamping elements, chains, and cables are engineered to provide a secure, compliant solution that minimizes downtime and supports equipment longevity—ideal for OEMs and MROs across North America's manufacturing, packaging, automation, and food processing industries.
