Thin Line Shaft Collars

Thin line shaft collars are designed for applications with space and weight restrictions in industries such as packaging, printing, medical, and food, and are particularly suitable for split hub componentry such as encoders. They function as clamps, positioners, guides, spacers, and stops in a smaller profile than traditional shaft collars. Two-piece styles have a balanced design for higher RPM applications. Most bore sizes are available with different outer diameter and width dimensions and screw sizes allowing the user to match space limitations and holding power with their application requirements. Ruland manufactures double thin line shaft collars in lightweight 2024 aluminum and 303 stainless steel. Bore sizes range from 3/16" to 1-1/2" and 5mm to 40mm.

Features
