Stock Drive Products & Sterling Instrument - SDP/SI 65.1mm Overall Length Neo-Flex Coupling With 4mm / 4mm Bores on either sides. Allowed for Shaft to Isolation S50PLRM0404

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 Summary
Powered by GS/AI

The S50PLRM0404 is a metric Neo-Flex coupling with 4 mm bore sizes on both hubs, designed for shaft-to-shaft torque transmission with torsional vibration isolation. It features 303 stainless steel hubs and a molded neoprene center with a durometer of 73, providing ribbed smooth-style misalignment compensation up to 8° angular offset and 0.25 mm lateral offset. The coupling has a maximum torque capacity of 65.1 N·m and an overall length of 65.1 mm. Its set screw hubs include a spot-drilled feature for secure shaft clamping.
