300 Series Neckring

Product catalog summary

Introduction
The document describes the "300 series" of enhanced mechanisms, specifically focusing on the Backlash-Free Neckring Mechanism used in hollow glass manufacturing. This mechanism features significant improvements over previous designs.

Specifications

The mechanism replaces the old splined shaft with three axial shafts sliding on hardened bushings.
Pneumatic chambers in each arm holder are sealed with low friction seals.
Accurate machining ensures precise alignment without mechanical adjustments.
Redesigned casting and geometry reduce moving masses and inertia.

Features

Optimized air ducts for balanced arm motion.
Reduced weight and seal friction.
Zero backlash and symmetrical motion even at low speeds.

Advantages

Smoother and more accurate mechanism response when opening.
Improved motion speed.
60% reduction in compressed air leakage.
Long service life and repairability for multiple machine campaigns.

Neckring Configurations

Basic Group
With needle bearings at shaft ends, one side air entry
With needle bearings at shaft ends, two side air entry
