Shear pin torque limiters are a simple, cost-effective design for protecting equipment from torque overloads. In their most basic form, they incorporate a pin (or, for very high torque ratings, multiple pins) inserted between two rotating elements, such as discs or flanges. When torque is being transmitted from the driving to the driven load, the […]

How do ball detent torque limiters work and when are they used?
Rotating equipment such as motors, gearboxes, and fans can experience a torque overload if the system encounters an unexpected malfunction such as a jam or crash of the driven load. One way to protect these expensive components — and to avoid physical injury to personnel — is to install a torque limiter in the drive […]
New flexible coupling from SDP/SI features vibration damping technology
Stock Drive Products/Sterling Instrument (SDP/SI) has debuted several new series of high-gain couplings. These Antivibration Flexible Couplings are designed for use with high gain servomotors. When a servomotor drives a mechanism, as in applications such as semiconductor manufacturing equipment, blood analyzers or high-speed printers, a change in direction causes a phenomenon called hunting. Hunting is […]
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 […]
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 […]
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 […]
Helical Products names HC Pacific as its new global partner
Helical Products, a precision metal components company of MW Industries, announced its appointment of HC Pacific as its master distribution partner for its standard HELI-CAL Flexure flexible coupling product line. Under the new partnership, HC Pacific will provide this state-of-the-art coupling solution to the domestic marketplace. This agreement, effective October 1, 2017, will expand HC […]
New Sure-Flex Plus coupling cost savings calculator from TB Wood’s
TB Wood’s has created a new program that allows users to quantify just how significant the savings can be when replacing a copy-cat coupling sleeve with the high performance Sure-Flex Plus EPDM or Neoprene sleeve. The program is now available at www.tbwoods.com or it can be installed as a smartphone app on any Android or […]
