THK HSR20 Linear Motion Guide Rail Bearing from Canada
The THK HSR20 is a precision linear bearing system consisting of a rail and carriage with recirculating steel balls, designed for smooth linear motion in automation equipment. It falls under HTS 8482.10.5012 as a linear ball bearing, distinct from radial ball bearings, used in semiconductor wafer handling stages for precise positioning.

Import Tips
• Verify dynamic/static load ratings and precision class (e.g
• C0-C3) in technical specs for correct subheading classification
• Include manufacturer test certificates showing ball recirculation mechanism to confirm as ball-type linear bearing
• Avoid misclassification as plain shaft bearings; provide CAD drawings illustrating rolling elements
