Commonly used when equipment (e.g., pumps, motors) cannot be positioned close together. The spacer acts as a rigid or adjustable component to bridge the gap.<\/li>\n<li><strong>Flexible Coupling<\/strong>: Focuses on accommodating misalignment (angular, parallel, or axial) and absorbing vibrations\/shock loads.

Maintenance may involve checking spacer integrity.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Flexible Coupling<\/strong>:\n<ul>\n<li>Tolerates minor misalignment, easing installation. Maintenance focuses on wear of flexible elements (e.g., replacing rubber inserts).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>Material Considerations<\/strong>:\n<ul>\n<li><strong>Spacer Coupling<\/strong>: Typically metallic (steel, aluminum) for durability in maintaining distance. Flexible variants may include elastomers.<\/li>\n<li><strong>Flexible Coupling<\/strong>: Combines metals with flexible materials (rubber, urethane) or uses flexible metal components (e.g., stainless steel discs).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>Some couplings integrate both features (e.g., flexible spacer couplings), offering both spacing and misalignment accommodation. However, the core distinction remains their primary purpose: spacing vs. flexibility. Choose a spacer coupling when distance is critical, and a flexible coupling when movement or misalignment is the main concern.<\/p>\n<\/div>\n<\/div>\n<\/div>",
