AURORA® spherical interfaces are designed to ensure robustness, accuracy and consistent performance even under loads, vibration and shock. These features are particularly important in the aircraft sector, where components must maintain stable performance and controlled clearance over time.

The sliding operating principle allows the bearing to accommodate movement and misalignment, contributing to the overall stability of the system in which it is installed.

The D Series couplings stand out with their six-beam design, which delivers superior torsional rigidity compared to traditional one- or four-beam couplings. This configuration ensures high accuracy in motion transmission even under dynamic loads and operational variations. Additionally, the ability to compensate for up to 7° of angular misalignment and significant axial displacement makes them particularly suitable for situations where perfect shaft alignment cannot always be guaranteed.

Dimensionally, the couplings offer an expanded bore range from 4 mm to 25 mm, covering a wide variety of application requirements. Their longer length, relative to other Ruland couplings of the same size, provides an additional advantage for applications with extended shaft separations. The anodized finish further enhances corrosion resistance, ensuring durability even in demanding industrial environments.

PERMAGLIDE® is a registered trademark of KS Gleitlager GmbH and clearly reflects the core performance of these products: durable sliding capability with limited wear over time.

The technology is based on a metal backing coated with a synthetic sliding layer, creating a composite structure that merges:

• excellent sliding and low-friction properties  
• high mechanical strength
• good thermal resistance

By integrating permanent lubricants directly into the synthetic matrix, many PERMAGLIDE® bearings can operate without the need for external lubrication with oil or grease. This makes them particularly suitable for applications where maintenance must be minimized or where lubrication is difficult to manage

The GE .. SEJR.ICP series features an outer ring in duplex stainless steel AISI 318L, precision-machined and made in a single piece without cuts to ensure greater structural strength and optimized load distribution. This design enhances corrosion resistance and extends operational life in saline environments.

The spherical inner ring is made of advanced thermosetting composite L2 Marine, composed of technical fabrics impregnated with resins and solid lubricants. This material is specifically designed for naval use, providing smooth movement and stability even in the presence of water.

RELS.. side seals can be installed on rod ends of different designs and materials. Their construction allows quick and simple installation without any modification to the rod end, while still permitting full rotation of the inner spherical ring.
Once installed, the seals form a protective barrier that significantly reduces the penetration by contaminants, helping to preserve the functional characteristics of the spherical joint.

Unlike conventional systems, where coupling occurs through sliding between spherical surfaces, the new Rodobal components integrate steel balls as rolling elements between the inner ring and the head.
This design drastically reduces contact points and, consequently, friction, wear and detachment moments. The result? Quick starts, smooth movements and high performance even in the presence of repeated dynamic cycles.
Thanks to the reduced contact surface and optimised load distribution, these components also allow high rotation speeds, comparable to rolling oscillating bearings, increasing efficiency in advanced kinematic systems.
