Short Rigid Couplings
Short rigid couplings can be used in applications where space is limited. The short rigid coupling has a reduced torque capability compared to a standard rigid coupling due to its use of a single socket head cap screw per shaft. However, the compact size of the collar reduces inertia making it ideal for motion control applications. Ruland manufactures short rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and high-strength 2024 aluminum. Bore sizes range from 1/8" to 2" and 6mm to 25mm.
Features Does not mar the shaft
Superior fit, finish and holding power
Excellent for high axial loads
Transmit torque in confined spaces
Step bores available
Additional sizes available
RoHS3 and REACH Compliant
Width tolerance: +.003"/-.010"
Temperature Range (Deg. F)Steel:
-40° to 350°
Aluminum:
-40° to 225°
Stainless:
-40° to 350°
