This set includes 4 SBR16 linear rail stop collars made from aluminum alloy. Each stop collar is a shaft endstop fixing ring with a screw, designed to clamp securely to an SBR16 linear rail. Key benefits Prevent overtravel: act as reliable physical stops to limit motion and protect your components. Easy to install and adjust: slide onto the rail and tighten the screw to fix at the desired position. Lightweight and durable: made from aluminum alloy for strength without adding excessive weight. Versatile stopping solution: compatible with SBR16 rails to provide precise end stops for various applications. Key attributes Compatibility: SBR16 linear rails Material: Aluminum alloy Type: Shaft stop collar / endstop fixing ring Include: Screw for clamping Quantity: 4 pieces Specifications and features Fourpiece set for multiple stopping positions or parallel installations Designed specifically for SBR16 rail systems Provides a secure, clampon endstop along the rail Includes screws to fasten the collar in place Usage and installation Slide the collar onto the SBR16 rail at the desired stopping position Align the collar to the required location Tighten the included screw to fix the collar in place Use multiple collars to create end stops for different components or axes as needed Applications CNC machines: establish fixed end stops on the Xaxis or other axes driven by SBR16 rails 3D printers: set precise travel limits and reference positions along the rail Automation and linear motion systems: provide reliable shaft limits and position references on SBR16 railbased setups Notes This product is a fourpiece set of aluminum alloy stop collars with screws, designed specifically for SBR16 linear rails. Use as end stops or shaft limit fixing rings as part of your railbased motion system.
