Rollon Corp, a global leader in linear motion systems, this week launched the HVC-MG and H1C-MG telescopic rails. The new MG version integrates magnets that allow the sequential opening of the rail elements.

“After successfully introducing this technology on the HGT range, we are now extending it to additional telescopic rail families,” says Andrea Tosi, vice president of technology at Rollon. “The integrated magnets enable an ideal combination of high load capacity and smooth and controlled motion. This development reflects our ongoing commitment to engineering solutions that go beyond meeting technical specifications, addressing the real operational challenges our customers face across industrial applications.”

Founded in 1975, Rollon designs and manufactures highly specialized linear motion systems. Since 2018, the Norton Shores, Mich.-based company has been part of The Timken Co., contributing to its growing portfolio linear components, actuators and systems, ball screws, and rotational units.

Magnets make linear motion smoother

Rollon said the magnets in its new rails deliver improved load management, smoother extension, and increased durability, even under intensive operating conditions. The MG version, available for Sizes 54 and 68 of HVC and for Size 68 of H1C, also features a redesigned ball cage with reduced pitch, combined with end blocks incorporating internal magnets.

The reduced pitch increases the number of balls within the same cage length, resulting in higher load capacity without changes to overall dimensions, according to Rollon.

The integrated magnets also enable a defined motion sequence of the rail elements during extension, improving control and reducing the force required to open the rail. This combination enables the handling of higher loads while helping to improve overall ergonomics, the company said.

It added that the optimized load distribution aids in reducing stress on the raceways, contributing to extended service life and more consistent long-term performance.

The HVC and H1C telescopic rails are fully and over-extending solutions, respectively, designed to maximize accessibility while minimizing space requirements, said Rollon. The company makes all of its rails and sliders from steel. The rails feature zinc electroplating and comply with REACH and RoHS standards.

Rollon offers additional surface treatments to enhance resistance in harsh environments. It can also supply HVC slides in stainless steel for superior corrosion protection.

Rollon builds HVC and H1C for demanding rail applications

Engineered for high rigidity and low deflection, HVC and H1C rails are used across multiple industries, including construction and industrial machinery. At the same time, their characteristics make them particularly suitable for the railway industry, where reliability and service life are critical, Rollon said.

Typical applications include extraction of battery compartments and other onboard equipment that require both easy accessibility and reliable structural support. In railway applications, components must support safe and ergonomic access for operators during maintenance while withstanding continuous exposure to shocks, vibrations, and environmental factors such as humidity and contaminants. In this context, smooth motion is not only a matter of usability but also of safety and operational efficiency.

“The MG version directly addresses these needs by improving motion control and reducing operating forces, even under heavy loads,” said Tosi.

With the launch of the HVC-MG and H1C-MG, Rollon said it has strengthened its portfolio of high-performance linear motion solutions. The company said it has a special focus on tailored solutions, and its products serve markets such as industrial automation, aerospace, medical equipment, and material handling.
