Sliding Block Couplings Overview Sliding block couplings connect two shafts while allowing axial movement and accommodating minor angular misalignment. They provide reliable torque transmission in systems with movement, thermal expansion, or dynamic loading, with a compact and robust design suitable for industrial environments. Key benefits Enables axial travel without disconnecting the drive Maintains alignment while accommodating angular misalignment Provides smooth torque transmission with low backlash Robust construction for demanding industrial use Simple integration with common shaft sizes and mounting arrangements Attributes at a glance Function Transmits torque between two shafts while allowing axial sliding and limited angular misalignment Compatibility Available for multiple bore sizes and standard shaft styles; compatibility varies by model Suitable for common metric and imperial shaft standards depending on SKU Size Offered in a range of bore sizes and overall lengths; exact dimensions are specified per model or SKU Material Material options vary by model; typical selections include durable metals with appropriate finishes or coatings Performance Engineered for dependable torque transfer, controlled axial movement, and long service life under industrial conditions Specifications and selection Refer to the product SKU for exact bore size, overall length, mounting configuration, and material options Choose a model that matches your shaft diameter, mounting pattern, and expected axial travel Verify compatibility with your application's operating environment, including temperature, load, and exposure to corrosion Typical use scenarios CNC machine tools with a sliding or thermally expanding component where axial movement must be accommodated without disconnecting the drive Packaging lines where a motor shaft drives a conveyor or rotor that experiences slight axial motion during operation Robotic or automation systems linking a motor to a linear actuator or flexible link where precise torque transmission remains important despite small misalignments Installation and maintenance Ensure bore size and mounting holes match the connected shafts and rails Secure setscrews or retaining features as specified for the model Inspect for wear and corrosion during routine maintenance; if signs of wear or reduced performance are detected Follow manufacturer installation guidelines for torque specs and alignment procedures Notes Material finishes and exact specifications vary by model; consult the product page or datasheet for precise information This description reflects general characteristics of sliding block couplings; verify modelspecific capabilities before selection and use
