Custom Nitrile Butadiene Rubber Roller

The AstraRoll Custom Nitrile Butadiene Rubber Roller (NBR Roller) is designed to provide long-lasting durability, exceptional oil immunity, and uniform pressure distribution for demanding roll-to-roll converting, printing, and liquid application systems. In modern continuous manufacturing—such as offset printing, steel sheet coating, and leather processing—rollers are routinely exposed to petroleum-based fluids, lubricants, and aggressive ink chemicals. Standard rubber compounds often absorb these solvents, causing localized swelling, softening, loss of hardness, or premature surface breakdown.

Our specialized NBR rubber rollers eliminate these process vulnerabilities. By selecting high-acrylonitrile (ACN) content polymer bases, AstraRoll formulates a cross-linked elastomer matrix that actively repels oils and non-polar solvents. Precision-ground to micron-level geometric tolerances on automated CNC machinery, each NBR shaft guarantees steady contact friction, flawless ink/liquid metering, and zero web-tracking vibration, even under high-speed, multi-shift operating conditions.

Applications & Industry Uses

Printing & Graphic Arts: Essential for offset inking rollers, dampening system rollers, and gravure liquid application shafts using oil-based and solvent inks.

Metal Processing & Steel Coating: Used as oiling rollers, squeeze rollers, and feeding rolls in continuous steel strip processing, tin-plating, and coil coating lines.

Converting & Packaging Machinery: Ideal for glue application, laminating pressure nips, and web-guiding loops running flexible films, paper, and foils.

Textile & Leather Manufacturing: Widely used in liquid squeezing, dye liquor padding, and oil-treating operations where mechanical abrasion and chemical exposure are constant.

Why Choose AstraRoll's NBR Rubber Roller?

Optimized High-ACN Formulation Prevents Oil Swelling:

Exposure to mineral oils and petroleum inks can cause inferior rubber to swell and lose its structural dimensions. AstraRoll utilizes high-ACN content nitrile matrices, keeping swelling ratios to absolute minimums and preserving exact roller outer diameters over long service cycles.

High Abrasion & Tear Resistance for Extended Service Life:

Continuous material friction wears down soft elastomers rapidly. Our NBR compound boasts high tensile strength and superior tear resistance, allowing the roller to withstand heavy mechanical shear, edge-wear from traveling webs, and high linear nip pressures.

Advanced Autoclave Vulcanization Prevents Delamination:

Heavy shear forces can tear rubber sleeves away from their steel shafts. We treat every metal mandrel with specialized chemical bonding primers prior to computer-controlled autoclave curing, creating an unbreakable fusion between the metal core and NBR jacket.

Micron-Level CNC Precision for Flawless Contact Synchronization:

Any rotational eccentricity causes ink banding, uneven coating thickness, or film wrinkling. Every AstraRoll NBR cylinder is finish-ground on automated CNC tooling to achieve an ultra-strict ≤0.015 mm TIR, securing uniform pressure and parallel contact across the entire web.
