Motion Control Couplings

Parker PD Series couplers are suitable for connecting or disconnecting diagnostic test port connectors with nipples (male thread end) to provide a mechanical sealing (rated at 6000 PSI) and some degree of misalignment between two components. These couplings feature galvanised steel construction for maximum corrosion resistance, push to connect operation for quick interlocking, flush face valves for minimising air intrusion & spillage and nitrile sealant for leakproof bonding. They are compliant with SAE standards that allow global interchangeability with other test point couplings having similar specifications and are available in NPTF and UNF type connections.

Lovejoy BWLC Series bellows clamp style couplings provide flexibility, misalignment compensation and torque transmission in various applications, such as motion control systems, robotics, industrial machinery, pumps and compressors. They consist of a steel bellow element and two aluminium / steel hubs that accommodates angular, parallel and axial misalignments between connected shafts while providing high torsional stiffness for accuracy and repeatability. The hubs can be easily mounted onto the shafts with the bellow positioned in between by using screws or clamps and reducing stress / wear on the connected equipment.

Motion control beam couplings are flexible couplings that use either one or more spiral slots cut in a single metal rod piece, thereby forming a spring centre section known as a beam or helical coil. The beam portions of these couplings flex for accommodating misalignments while continuing to transfer power between the attached shafts.
Lovejoy aluminium clamp style single beam couplings are designed for parallel, angular & axial misalignments of shafts requiring less weight & zero backlash. Lovejoy clamp style single beam couplings are recommended for use in light duty applications such as coupling a servo motor to a lead screw in motion control systems.
These single beam couplings have quicker response time as compared to stainless steel couplers. These beam couplings accommodate parallel misalignment up to 0.005 inches, angular misalignments up to 5 degrees and axial motion up to 0.01 inches. These clamp-style beam couplings can either be installed or replaced without the movement of shafts. These Lovejoy single beam couplings feature single piece construction with anodised aluminium finish to provide longer service life in comparison to couplings with moving parts. They are resistant to corrosion and can be operated at a maximum temperature of 200 degrees F.

Ruland Manufacturing oldham coupling disks feature a three-piece assembly with a balanced design comprising of two hubs and a center disk.The three-piece design facilitates a highly customisable coupling which comfortably combines clamp or set screw hubs with Inch, Metric, keyed and keyless bores. These couplings can accommodate all forms of misalignment and are useful in applications with high parallel misalignments.

Ruland Manufacturing MW Series four beam couplings feature two sets of two spiral cuts to offer high torque capacity & low windup. These spiral couplings have a balanced design for reduced vibration at high speed. They come with small bearings for low radial forces and efficient performance. These set screw style couplings feature a compact design that fits into confined spaces and allows easy retrofits in existing equipment. They are manufactured from 7075 aluminium for light weight & low inertia, and 303 stainless steel for increased torque capability.

Ruland Manufacturing MBC Series motion control couplings are installed on two shafts required to move at the same speed & in the same direction, while preventing misalignment between the shafts. They are ideal for small, dual-shaft applications to run medical equipment, robots, metering devices and computers. The one-piece design of the couplings easily fits the shafts, without causing marring. They are held in place via cap screws and have a spiral slot in the centre, to dampen vibrations. Choose from a wide range of motion control couplings, available in anodised aluminium and black anodised finish variants on Raptor Supplies.

Ruland Manufacturing MDCD Series motion control couplings are aluminium made shaft couplings designed to remove misalignments up to 2 degrees. The balanced one-piece design reduces vibration at high speeds, provides zero backlashes and easily fits the shaft, without causing marring. The double disc mechanism in the centre comprises 2 anodised aluminium hubs, 2 sets of thin stainless steel disc springs and a centre spacer to accommodate misalignment. They are held in place via cap screws and have a spiral slot in the centre to dampen vibrations. Choose from a wide range of 1-piece motion control couplings, available in 25, 50, 100 and 180 inch-lb torque ratings.
