EXPANDED RANGE OF SHORT RIGID COUPLINGS GIVES DESIGNERS MORE CHOICE
Ruland has expanded its range of short rigid couplings, giving designers the widest variety to suit application demands
T
o give designers a wider variety of standard short rigid coupling options, Ruland has recently expanded its range of short rigid
couplings to include keyways and step bore sizes. Short rigid couplings – also referred to as double-wide shaft collars – are ideal for applications with space or weight restrictions, or where designers prefer a simplified assembly with fewer fewer screws than traditional rigid couplings.
MEETING DESIGN DEMANDS Many servo-driven applications in industries such as semiconductor, medical, packaging and robotics, require a coupling with torque and torsional stiffness needs that exceed the capacity of a flexible coupling. While a traditional rigid coupling meets the performance requirements,
Summary:
• Short rigid couplings offered with step bore sizes and keyways • Higher torque and torsional stiffness compared to flexible couplings • One- and two-piece styles available • Manufactured and inventoried in Ruland’s Marlborough, Massachusetts factory
• Available in the UK from Acorn Industrial Services
they often have different envelope requirements. Short rigid couplings, however, offer
significantly more torque and torsional stiffness than flexible couplings while fitting in a similar envelope. With keyways and step bore sizes,
designers now have the widest variety of standard short rigid couplings to choose from to fit the needs of their application. The short rigid couplings are available in
steel for the highest torque and torsional stiffness capabilities; stainless steel for corrosion resistance; and aluminium for low inertia. Designers must be careful when interchanging traditional flexible couplings for steel and stainless steel short rigid couplings that significantly increase inertia. Ruland manufactures its short rigid
couplings in one- and two-piece clamping styles. Furthermore, they are available in straight or step bore combinations, with or without keyways, in bore sizes ranging from 6mm to 25mm or 1/8 in to 2in.
