Reliance Mechatronics launched a flexible shaft coupling that offers high torsional stiffness, low bearing load, long service life and low kinematic error. The Reli-a-Flex coupling achieves high torsional stiffness by placing the beams radially around the coupling. Unlike other coupling with spiral pattern beams, the radial beams support the drive loads in compression. The center […]

Couplings from Zero-Max now available with hubs for k6, j6 shafts
ServoClass couplings in both Single and Double Flex models are now available with hubs for k6 and j6 shafts. These couplings from Zero-Max provide high torsional stiffness and are designed to handle high speed reversing loads and precise positioning requirements in today’s demanding servomotor applications. The Single and Double Flex ServoClass models handle bore diameters […]
Stafford Large Bore Shaft Collars and Rigid Couplings
Large bore shaft collars and couplings that can be custom engineered for drive train applications in wind power generation systems are available from Stafford Manufacturing Corp. of Wilmington, Massachusetts. Stafford Large Bore Shaft Collars and Rigid Couplings are custom engineered for applications up to 16” and 8” I.D., respectively, and come in one- and two-piece […]
POSITAL-FRABA multi-turn hollow shaft kit encoders — Rockwell Encompass Complementary Products
POSTIAL-FRABA’s new hollow-shaft kit encoders are now a complementary product in Rockwell Automation’s PartnerNetwork Encompass program. These new products mark a significant innovation for industrial motion control. Until now, almost all through or hollow-shaft encoders have been limited to a single-turn measurement range, largely because fully satisfactory multi-turn technology has been not been available. POSITAL […]
Dual-keyed rigid couplings prevent axial and radial slippage
Stafford Manufacturing Corp. introduces a line of rigid couplings for heavy, suspended loads on shafts used in mixers, pumps, fans and related drive systems. Stafford Dual-Keyed Rigid Couplings feature axial and annular keyways to provide additional security for high torque and axial load applications. Designed to prevent axial and radial slippage with higher loads for […]
Jaw spider couplings from Miki Pulley designed for wide range of applications
Miki Pulley’s ALS couplings are general-purpose power transmission couplings designed to transmit torque by connecting two shafts while damping system vibrations and accommodating misalignment. With a “Curved Jaw” design, ALS couplings feature a polyurethane elastomer element (called the spider) between two sintered aluminum hubs. The three-component assembly fits together with a jaw from each hub […]
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 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 rapid […]
9 considerations when picking servocouplings for servo applications — and 4 references from couplingtips.com
Couplings for servo applications usually connect precision drives to sensitive loads, so they cannot induce any error. That’s why servocouplings should be zero backlash — to prevent issues with timing and predictability (not to mention failures due to hammering on reversing axes). Couplings for servo applications must also have high torsional stiffness while imparting slight […]
New hollow-shaft encoders from HEIDENHAIN provide functional machine safety
HEIDENHAIN’s new series of functionally safe hollow-shaft connection rotary encoders, the ECN/EQN/ERN 400 series, are especially useful in applications where quick machine shut-off is required in dangerous situations. Featuring a new shaft coupling which provides mechanical fault exclusion for connection to the customer’s machine shaft, these new encoders are of particular use in safety-related applications […]
Four of the top mechanical coupling technical updates for 2016
Couplings are simple devices that connect two shafts together — usually to fix motor output shafts to other rotating equipment to transmit motion. Dictating the most suitable coupling are (among other things) required precision of velocity transmission and overall torque. Below are some recent updates on couplings from motioncontroltips.com Design World sister site couplingtips.com. Managed by […]
