Ruland RSS8-4-2-A, 0.250" x 0.125" Short Slit Coupling, Aluminum, Set Screw Style, 0.512" OD, 0.661" length

PRODUCT SPECIFICATIONS

Ruland RSS8-4-2-A is a set screw style slit coupling with 0.2500" x 0.1250" bores, 0.512" OD, and 0.661" length. It is manufactured from a single piece of material and has two sets of intermittent slit cuts allowing for a maintenance-free coupling with high torsional stiffness in relation to comparable couplings, such as beam type. RSS8-4-2-A is commonly used in precise positioning applications found in semiconductor, medical, and test and measurement equipment. This short style slit coupling is ideal for compact installations where the long type may not fit. It is a suitable alternative to comparatively sized disc couplings due to the ability to accommodate all forms of misalignment whereas a single disc coupling has no accomodation for parallel misalignment. RSS8-4-2-A is zero-backlash, has a balanced design for reduced vibration at speeds up to 30,000 RPM, and can accommodate all forms of misalignment with light bearing loads. It is manufactured by Reliance Precision Ltd. in their County Cork, Ireland factory from 7075 aluminum for lightweight and low inertia. RSS8-4-2-A is inventoried by Ruland and RoHS3 and REACH compliant.
