The A 5R 3-035 is a rubber spider for jaw-type flexible couplings, designed to be assembled with A 5D 3-035.. series hubs to form a complete coupling. It features an NBR rubber compound with 80A ± 5 Durometer hardness, capable of compensating for up to 1° angular misalignment and 0.015 inch lateral offset. It operates within a temperature range of -40°F to +212°F and is oil resistant. The spider has four legs and is used with couplings rated for 3.5 lbf·in torque at 1800 rpm, transmitting 0.10 hp under those conditions. The coupling series has a 1/8 inch bore and uses a #6-32 screw for the set screw. The entire assembly has an overall length of 13/16 inch and an outer diameter of 5/8 inch.
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.
