Product ReleasePneumatic - Endurance Technology Extends Life of Rodless Pneumatic Cylinders
 TOL-O-MATIC Inc., announces Endurance TechnologySM innovations for their BC Series of pneumatic band cylinders. Endurance Technology assures that every TOL-O-MATIC Band Cylinder is designed for long life in the most demanding applications. Four complete lines of rodless band cylinders, including the BC4, BC2, BC3 and BC3D, deliver peak performance for a range of industrial load requirements. "BC Series cylinders are built for durability. Only the highest quality materials are used for a more cost effective and longer lasting solution," said Cory Danks, Tol-O-Matic Product Manager. BC Series cylinders feature a patented stainless-steel band, rigid extruded aluminum tube and internal air cushioning. In addition, the load is supported through the entire stroke, keeping seal wear to a minimum. Endurance Technology makes BC Series cylinders ideal for a variety of demanding applications. For example, the BC4 features a patented floating bearing system that is self-lubricating and runs the entire length of the carrier for maximum bearing surface. And a durable, engineered resin piston offers 50% greater bearing area. The engineered resin load bearings and independent piston featured in the BC2 offer consistently low friction for longer wear and seal life. The BC3 also offers a longer seal life and less friction—even with changing load orientation—and a recirculating ball bearing system supports the load for consistent performance. The BC3D includes a heavy-duty 180º carrier that wraps around the housing for higher moment load capacity and a larger load-mounting surface. TOL-O-MATIC Band Cylinders are used in a wide variety of applications in the packaging, automotive, food and beverage, material handling & conveying, plastic injection molding, metal processing, paper & textiles, medical, electronics and printing industries. TOL-O-MATIC, Inc. is an ISO 9001:2000 certified manufacturer with sales representation throughout the world. TOL-O-MATIC has been designing and building high quality linear motion control products for over 50 years. |

Tol-O-Matic has announced the SW Series Servo Welding Actuator—a patented new design that offers compact design, significantly extended service life and zero maintenance. Available in high performance roller screw or a ball screw models, the SW Series actuator features rated life at weld force exceeding 10 million cycles for the roller screw and 5 million for the ball screw when side loading is within specification. In many applications, service life can exceed these levels.
The SW Series Actuators incorporate an 8-pole Nd-Fe-B hollow core rotor with skewed stator laminations that provides low cogging torque. This design results in superior force repeatability of ±3.0% over millions of weld cycles, with actual field results to ±1.5%, independent of position. The design also results in greatly improved weld quality, offering weld force up to 2,500 pounds (11.12kN) and peak force of 4,400 pounds (19.57kN).
Tol-O-Matic has announced its new Absolute Position Feedback (APF) technology, the first fully-integrated linear actuator sensor that eliminates the need for homing routines. APF-equipped Tol-O-Matic actuators provide analog feedback to the controller or PLC to determine actual load position. Work point variances can also be accommodated throughout the cycle, eliminating stoppage for manual set-ups. Systems with APF provide position feedback as soon as power is applied, allowing immediate resumption from shutdowns, resets and power losses. The APF option is currently available for Tol-O-Matic BC3 pneumatic and B3S electric series actuators, and unlike fixed length sensors, can be ordered in incremental stroke lengths from 2 to 156 inches.
“APF is fully integrated within the actuator body, eliminating the need for complex mounting and also reducing the chance of damage to the transducer,” said Michael Dornfeld, Tol-O-Matic Project Engineer.
ServoGate™ Electric Linear Actuator replaces complex hydraulic valve gating for improved quality and repeatability TOL-O-MATIC has announced the ServoGate™—a new, patent-pending electric servo actuator designed for valve gate control applications, in particular those in injection molding applications. The ServoGate actuator is the first compact, high performance electric actuator developed specifically to replace the bulky hydraulic valve manifolds and hydraulic power systems used for valve gate control and sequencing. By eliminating a number of variables found in fluid power systems, such as fluid bulk modulus and viscosity changes, the ServoGate actuator delivers precise gate control in a compact package measuring less than 7.0” X 7.0” (17.8 cm X 17.8 cm). “For years, veterans of hot runner molding technology have looked for the perfect valve gate. ServoGate’s all-electric solution improves shot accuracy and repeatability of injection molded parts, regardless of whether it’s applied to a standard or all-electric injection press," said Gary Rosengren, Director of Engineering.
