Stock Drive Products & Sterling Instrument - SDP/SI 18mm & 18mm Bores (Side1 & Side2), Zero Backlash Miniature Slit Type Flexible Coupling S50MSKMA40K18K18

Description
Couplings Types Couplings can be divided into two categories: flexible and rigid. Both types are used to connect two rotating shafts driven by a motor and transmit torque and angular velocity; however, flexible couplings and shafts are designed to accommodate angular misalignment, angular offset, axial movement, and a variety of load conditions. A flexible coupling is pliable due to the twisting and compression of a durable, adaptable material, like neoprene, rubber, or silicone. Flexibility can also be achieved with thin metal disks, corrugated aluminum bellows (bellows couplings), or even a stainless-steel ball (miniature ball couplings). Some materials can provide vibration reduction, as in our precision flexible antivibration couplings. Rigid couplings are limited by comparison; rigid couplings are used when shafts are already positioned in precise lateral and angular alignment. Their rigid design inhibits shaft misalignment. They can generally transmit more power than flexible couplings due to their rigidity. Even the most complicated application challenges can be solved by our skilled engineers, they will identify the best coupling solution for your application. SDP/SI provides a comprehensive range of rigid and flexible couplings. Many of our precision couplings, including the Miniature Bellows Coupling and the Neo-Flex Coupling, have our patented Fairloc® Hub design, which solves phasing, timing, positioning, and frequent removal problems.

Datasheet
Datasheet Summary
Powered by GS/AI

The S50MSKMA40K18K18 is a miniature slit-type flexible coupling with 18 mm bores on both sides, designed for zero backlash and high torsional stiffness in precision motion control applications. It is made of anodized aluminum and has a body diameter of 40 mm and a length of 56 mm. The coupling accommodates a maximum angular offset of 2° and an axial offset of ±0.5 mm, with a torsional stiffness of 700 N·m/rad and a maximum torque capacity of 8 N·m. It is secured with an M5 set screw and complies with ISO projection standards for keyway alignment.
