Lug type air expanding shafts are strong and versatile, delivering superior performance in the widest range of converting unwind and rewind applications. Also, eliminate core damage, prevent roll slippage during fast startups and shutdowns, and minimize vibration at high web speeds. Designed for light- to heavy-duty applications with 1” (25mm) to 12"(300mm) ID cores, the lug type air expanding shaft is often used in center unwind and rewind applications with either paper or steel cores.
Tension Leaf type Air expanding shaft is suitable for a full range of converting and web production operations, with a fixed leaf design for greatest core and web concentricity. It is ideal for core or coreless winding, and features a 360° radial expanding grip. Its rugged construction and design are available for any diameter or length, in steel, aluminum or lightweight carbon, with special designs available for heavy duty and extra lightweight applications. Shaft weights for your specific application are available upon request.
The strip material of this strip type air inflated shaft is made of rubber with good clamping elasticity, so it can keep better concentricity, the strip type air inflated shaft body material is hard aluminum alloy or carbon steel, for which kind of shaft body material to use, it depends on material's weight, this strip type air inflated shaft can be used in the cutting, printing, rewinding, unwinding, labeling, and the other materials... Sunrise manufactures to your specificized strip type inflated air shaft to suit your equipment, including cantilevered or custom designs. The strip type air inflated shafts are guaranteed for one year against material and workmanship defects.
Foot mounted safety chuck is a specialized quick coupling used for web handling operations. In order to maintain the desired tension in a web, a shaft from which a roll is being unwound must be subject to a constant level of torque from a tension brake. Similarly, a shaft onto which a roll is being wound must be subject to a constant level of torque from a motor via a slip / tension clutch.
Those position indicators are used in various machinery regions, such as woodworking machine, packing machine, printing machine and so on. They are easily mounted on the spindle and control position variable, distance between rollers, gate widths, valves. Or any other equipment controlled by rotary or screw motion
Aluminum alloy guide roller adopts the high quality of aluminum, and use advanced processing technology, the surface is using anodic oxidation treatment, we have two types of this product: HV300 (white) or HV700 (tawny), roll body smooth finish is 0.8, dynamic balance is G2.5; Aluminum tube generally have 8-10 reinforcement. We can make slot roller according to customers' requirement, such as: Crossover aluminum roller, horizontal center, aluminum roller, roller, and cooling roller.
Strip type pneumatic air shaft core adaptors are the most economical solution to adjust an existing shaft to a larger core diameter. Mounting and dismounting takes just a few seconds, saving time and the cost of a new air expanding shaft.
The NAC pneumatic air clutches are normally air –operated at pressure up to 6 bar/ 90 psi. The maximum energy per engagement figures quoted is based on a frequency of engagement not exceeding 30 per hour.
DBK pneumatic air caliper disc brake is a complete pneumatic air caliper disc brake with several pieces of modules, more modules in quantity, larger force in braking. This air disc brake used to keep moving, rotating machine parts in constant tension or to stop them in a shorter time.
The STC-858A models of web tension controllers automatically control unwinding, intermediate, or winding tension by receiving signals from either the LS-TD or LC model of tension detector. These controllers generate a control voltage of 0 to 24V to the powder clutch/brake or hysteresis clutch/brake, or generate a torque command voltage of 0 to 5 V to the AC servo amplifier.

STC-002 manual tension controller is simple and convenient to applicate, compact, and easy to install. Output stability, using high-quality components and product quality. STC-002 manual tension controller can facilitate the achievement of tension control for the Thin-film printing process and winder which need to control the tension.
