Maximum grip performance

Nim-Cor's special Iso-Grip™ system of independent flanges provides maximum grip at all contact points along the core, achieving optimum torque. This unique design accommodates variations in the inside diameter of the web core, allowing the flanges to securely grip rolls of any continuously wound material to provide ease and speed in unwinding and rewinding.

Advantages of Iso-Grip™ System

• Independent flanges operate together, securing the load with firm, equalized pressure at every point.
• The system is customizable to fit your application by choosing lugs, large, small or midget buttons.
• Lugs, large and small buttons can be hardened for additional durability and serrated for increased torque.

Choice of material to suit application

Every application is different — there is no such thing as the "one size fits all" design. Nim-Cor offers airshafts in a variety of materials to meet the needs of its customers.

• Steel is the most popular choice, providing a cost effective shaft capable of meeting most applications.
• Aluminum is widely used, particularly where users are seeking to reduce the physical effort required in the handling of reels, and can accept lower load bearing limitations.
• Shafts made of Xymid™ Advanced Composites are capable of tackling any application and offer the best of both requirements, giving a shaft with high strength increased speed and reduced shaft deflection. Nim-Cor offers four different fiber modulus options, each one having specific application criteria.
• Stainless steel is used where the application involves high levels of hygiene, or in damp operating environments.

Whichever material is selected, all shafts are available in large, small and midget buttons or lug styles.

High-quality construction —

Nim-Cor airshafts are built to exacting standards for years of dependable service. Our Engineering Department verifies each design to ensure that the shaft will carry the loads specified and meet the expected operating conditions of speed and tension. This study covers both the reeling and work-handling operations.

All Nim-Cor journals are taper-fitted to provide for accurate alignment and concentricity and to permit easy removal. All shafts are tested prior to shipping to ensure that they meet the customer requirements and Nim-Cor's own quality standards.

Nim-Cor Iso-Grip™ Airshafts

Large Button Airshafts
This original and most popular version of the Iso-Grip™ System can be adapted to your unwind, center wind or surface wind operations. Choose from straight, staggered or offset button rows to match your application needs. Ideal for core I.D.'s over 2-1/2" and web widths greater than 6". Large buttons are 5/8" diameter pitched on 1-3/4" centers.

Small Button Airshafts
Unwind or rewind multiple narrow web widths as narrow as 1/4". Buttons can be ordered in straight, staggered or offset rows for maximum performance in your particular application. For core I.D.'s of 1-1/8" and up. Small buttons are 3/8" diameter pitched on 3/4" centers.

Midget Button Airshafts
Get optimum unwind, center or surface rewind performance with our Iso-Grip™ System midget button shafts. Select from straight, staggered or offset button sequence. For core I.D.'s of 1" or less. Midget buttons are 1/4" diameter pitched on 1/2" centers.

Lug-Type Airshafts
Utilize this style airshaft for web widths greater than 6" when working with steel, PVC and conventional cores. Lugs can be hardened for added durability. Or, choose our springless urethane lug for core I.D.'s of 2" or less. For core I.D.'s 2-1/2" and larger we use 2-5/16" long lugs on 5-1/8" centers. For core I.D.'s 2" and smaller we use urethane lugs 1-1/2" long, 2" on center.

External Bladder Airshafts
Nim-Cor's new lightweight external bladder shaft offers precision engineering and ease of handling for standard duty unwind and rewind applications. For ease of maintenance, bladders can be replaced in 15 minutes, and parts can be replaced without removing journals. Shafts are available in a variety of core sizes, and custome shafts are available.
