Ruland FCR16-4-4-A Clamping Beam Coupling, Polished Aluminum, Inch, 1/4" Bore A Diameter, 1/4" Bore B Diameter, 1" OD, 1-1/2" Length, 35 lb-in Nominal Torque

 Ean: 0634529008409   |    PartNumber: FCR16-4-4-A   |   Asin: B002SJXILE

Shaft Couplings - Flexbeam zero-backlash flexible couplings are machined from a single piece of aluminum and feature two sets of spiral cuts. The multiple cut design provides higher torque capabilities and greatly reduced wind-up compared to commodity type single beam couplings. The Flexbeam design provides superior parallel misalignment capabilities as well as angular misalignment, axial motion or any combination of all three. The clamp style also has the additional benefit of dynamic balancing due to the unique configuration of the socket head cap screws. The Flexbeam-3 couplings are ideal for light duty power transmission applications. These couplings feature larger body sizes and stronger beams to provide high torque capacity and very low wind-up, while not sacrificing misalignment capabilities. Flexbeam-2 couplings are designed specifically for precision applications such as encoders and tachometers. Flexbeam-2 provides extra flexibility to yield reduced bearing loads, and shorter industry standard lengths to fit in confined spaces and allow for easy retrofits in existing equipment. All Flexbeams handle up to 3 degrees of angular misalignment.

Flexible couplings are used to link 2 rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from 1 shaft to the other. Most flexible couplings consist of 2 hubs and 1 middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the 2 shafts. Shaft misalignment are generally either parallel or angular and cause complications to transmitting rotational power from 1 shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from 1 type of misalignment to another. Specification: Length: 24cm Outside Diameter: 15mm Bore Diameter: 6mm to 6mm Torque Range: 0.5N.m to 1.2N.m Material: Aluminium Alloy and TPU Feature: Designed for encoder; High flexibility, not easy to break; Simple structure, installation is convenient; Bushings are made of high-strength aluminum alloy; Elastomer is made of TPU, anti-oil and anti-oxidation; Package: 1 x Plastic Coupling

Features

  • 15mm Diameter X 24mm Length
  • Clamp-style mount for secure attachment to shaft
  • Accommodates angular, axial and parallel misalignment
  • Aluminum hubs for light weight, TPU elastomer for flexibility
  • Shaft couplers are applied for connect servo motor, stepper motor, encoder, machine platform etc.
