THE TABS

Types of New Cores/Rollers

Core Evaluation and Repair

Steel

We fabricate Engineered Steel cores with the typical grades of Carbon and Stainless steel.

Aluminum

Precision, lightweight rollers offer low inertia and high speed capability.

Carbon Composite

Lighter than aluminum. High strength and rigidity comparable to steel, very low inertia offers high speed capabilities, less vibration, and reduced bearing loads.

Fiberglass Sleeves

We in house manufacture fiberglass sleeves in a wide range of sizes. Contact us to determine if we have an existing mandrel for your specific sleeve system.

Idler

We can design and manufactured idler rolls with groove patterns and a variety of protective coatings to help with air removal, durability, and traction with any substrate.

Heated

We design and manufacture chill and heater rolls. Large and small, single and double shell, spiral wrapped and unwrapped, they are robust in design and made to exacting standards.

Chilled

We design and manufacture chill and heater rolls. Large and small, single and double shell, spiral wrapped and unwrapped, they are robust in design and made to exacting standards.

Plated

We can perform Chrome, Nickel, and Anodizing of Steel and Aluminum cores and journals to the surface finish you specify.

Covered Cores

All of the cores that we fabricate can be covered with our wide range of rubber and urethane compounds.

Acid Flushing

Keeping the internal surfaces of your heated or chilled roll clean by periodically flushing the residual build up of deposits to maintain the flow of the hot and cold liquids.

Static and Dynamic Roll Balancing

RotaDyne offers dynamic and static balancing, as well as whip analysis designed to keep your equipment in tip top shape. We balance to a variety of industry specifications.

Dye Penetration and Magniflux Testing

In addition to visual inspections and comparative analysis, ultrasound, magnetic particle testing, and dye penetrant testing are offered for checking microscopic cracks and flaws in the roller.

Grinding

The RotaDyne team can expertly handle in-house re-grinding to meet the original manufacturing specifications of your rollers – saving production down time, extending roller life, and maintaining high quality production standards.

Core and Journal Repair

No matter how bad a damaged journal looks (seized bearing spun on journal etc) many rolls can be saved by repair instead of replacement. RotaDyne can build up a damaged journal by welding, then machine it to like-new condition. Cracked or damaged welds can be removed and repaired.
