The unique split-in-half flex element and reversible hubs significantly decrease total costs by reducing inventory and assembly time. Rexnord Omega couplings are non-lubricated, material-flexing couplings utilizing a specially formulated polyurethane material engineered for maximum durability, strength, and fatigue resistance. The Rex Omega HSU coupling (green) is specifically designed for hot and humid conditions. Rexnord is […]

Ringfeder elastomer jaw couplings
The rotationally resilient couplings of the RINGFEDER series GWE, TNM, TNS, and TNB are puncture-proof and flexible in all directions and therefore compensate for angular, parallel, and axial shaft misalignments of the connected machines. Misalignments can be caused for example by inaccurate assembly, heat movements, or settling phenomena. Avoiding torsional vibration By virtue of the […]
Lovejoy reformulates S-Flex Endurance Couplings
Lovejoy’s redesigned S-Flex Shear Type coupling product is the highest quality and longest-lasting offering available in the marketplace. Lovejoy engineers reconfigured the material and have delivered a new and improved, longer-lasting EPDM rubber sleeve. Lovejoy introduced the redesigned product as “S-Flex Endurance Couplings” to signify the increased longevity and other performance improvements. The product launched […]
Optimum connection between drive and main spindle
Manufacturers set exceptionally high standards with regard to the quality of the connection between the main spindle and the drive of a machine tool: To ensure perfect operation of the machine, the connection must provide zero backlash and must be easy to establish. Furthermore, it must meet essential damping functions and compensate various types of […]
June Robotic Summit: Register now and we’ll see you in Boston
Our team hereby welcomes you to Boston in June for the 2019 Robotics Summit — June 5 and 6, 2019 to be exact. Focused on the design, development, manufacture, and delivery of commercial robotics, the Robotics Summit is actually co-located with the DeviceTalks event at the Seaport World Trade Center. As an attendee, expect to […]
Are you overlooking duty cycle in your coupling selection?
Duty cycle is a critical but often overlooked consideration during the coupling selection process. Critical elements like types of motion, potential shock load scenarios, and start/stop situations should all be evaluated when selecting a coupling for your next motion system application. Here, Bobby Watkins of Ruland Manufacturing gives us some insight on what to look […]
Step-Flex couplings from Miki Pulley improve ball screw performance
Miki Pulley’s Step-Flex Couplings improve ball screw performance while solving resonance and vibration problems. The Step-Flex is an altogether new class of shaft coupling. The Step-Flex coupling design has a two-part elastomer element combination. This assembly dampens vibration caused by the actuator carrier when struggling to find its home position by making small adjustments in […]
Dodge paraflex elements
Dodge Para-Flex elements are manufactured with reinforcing fabric tension cords that transmit much of the torque during operation and offer a wear indicator to the user when the element should be changed out. The uniform and centered beads, in the foot of the tire element prevent it from pulling out during operation. Additionally, the tire […]
Servo couplings: Stiffness, damping, hunting, and stabilization considerations
Here we address considerations when specifying servo couplings to satisfy servo requirements — ever-evolving specifications that become more demanding all the time. By Tetsuya Niwa • Director of product planning and development Kei Yamada • Product Manager — Product planning and development Hiroki Goto • engineering specialist Paulo Castelo • Technical solutions supervisor • NBK America […]
