    Our 1” to 2” Differential Shafts are direct friction style differential shafts. With low tension and easy roll positioning, this shaft can fit cores from 1” to 2” diameters. It can also have face lengths up to 18” and is ideally suited for cores in ¼” increments.

     

    Features
    The 1” to 2” Differential Shaft has three rows of external gripping elements spaced at 120 degrees and is able to slit rolls as narrow as 1/2" wide. It features a multiple bladder design that is a vast improvement over previous air or mechanical designs. Our differential shaft does not have any weak journal connections since it is made entirely from one piece of solid steel. This kind of one piece design is capable of holding more weight with less deflection.

    You can expect extremely low friction from the abrasion-resistant elements with this shaft. We have placed the abrasion-resistant elements to impart sensitive resistance to the core ID. There are also expanders along the entire length of the shaft, which allows for one or multiple cores to be placed anywhere along the shaft at the same time.

     

    Customization
    Our 1” to 2” Differential Shaft is custom designed to fit your specifications. When placing an order for the 1” to 2” Differential Shaft, we ask that you specify whether you need a quote for the cantilevered or flanged version so that we can make sure your differential shaft fit your needs and specifications.

    As with all of our shafts, chucks, and accessories we guarantee that your 1” to 2” Differential Shaft will be designed and manufactured to the same tolerances as all of our industry’s leading shafts.

    These shafts are typically available 4-5 weeks after ordering. Please contact our office for a more specific lead time.

    The Convertech Concentric Shaft is available in many variations.  Some are simple air shafts with larger body diameters or ledges to help hold the core more centered (concentric) on the shaft.  Others are air-mechanical where a piston pushed mechanical expanders that center the roll.  Yet others are fully mechanical and can be used in vacuum environments.

     

    Features
    The Concentric Shaft is truly a custom shaft that fits your purpose and ensures a smooth running core. This shaft has specific designs for wide and narrow web, light and heavy duty, and high torque shafts. The air, mechanical or mixed designs also assure concentric rotation of the cores. There are also lug and leaf styles available depending on the application.

    The Concentric Shaft can be designed with face lengths up to 80” and diameters from 70mm to 6” but is able to use an adapter to hold up to 12” diameter cores. Some Convertech Concentric Shaft features a fail save operation, where their natural state is expended and air is used to retract the expanders to allow roll changes.

     

    Customization
    Our Concentric Shafts are custom designed to fit your specifications. When placing an order for Concentric Shaft, we ask that you specify whether you need a quote for the double journal version so that we can make sure your Concentric Shaft fits your needs and specifications.

    With our Differential Air Shaft, you are able to run multiple rolls on a single shaft while maintaining equal tension on all rolls. The internal differential slip allows for running rolls with a wide range of core sizes and types without using cones, core stops, or spacers. It also will not have any “wobble” or side to side movement. Our Differential Air Shaft is easy, safe, reliable and efficient to use.

    Features
    With easily controlled tensions from under 0.15 PLI, it is able to wind multiple cores down to ½” width. It can also have face lengths up to 100” in 70mm – 10” Diameter.

    The Differential Air Shaft also has patented GlideLock™ Clutched Rollers that auto-lock to equalize tension on multiple width cores that can be placed anywhere on the shaft.  It features a bi-directional, internal clutching mechanism which actuates based on the location of each core on the shaft. When the shaft begins to rotate, the rollers under each core lock independently and apply tension to each individual core. As the material is wound onto the cores, the GlideLock™ Clutched Rollers self-adjust to ensure the correct tension. And slide bearings on each GlideLock™ Clutched Roller allow cores to slide on and off the shaft quickly and easily. Heavy, finished rolls slide effortlessly off the shaft and decrease load time.

    Our Lug Shaft is heavy duty shaft with steel or aluminum bodies and lugs available. This shaft has our QuickChange™ Bladder Change Cartridge that allows you to change bladders in minutes with common hand tools.

     

    Features
    Designed with the operator in mind, QuickChange™ Bladder Repair Cartridges are a unique feature of Convertech Lug Shafts. Each QuickChange™ Bladder Repair Cartridge is an all-inclusive repair part that can be kept in stock —much less expensively than the time lost during a typical lug shaft bladder repair. Using only common hand tools, such as pliers and hex wrenches, an operator can remove the old bladder cartridge, install, and position the replacement in a few minutes.

    No special banding tools or hydraulic presses are required. Ensure maximum uptime by keeping a spare bladder cartridge as a backup.
