Products classified under HTS 8482.10.50.12
THK HSR20 Linear Motion Guide Rail Bearing
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.
Bosch Rexroth R1651 Ball Monorail Guidance System
Bosch Rexroth R1651 features four rows of recirculating balls in a compact monorail design for high rigidity linear motion in CNC machines and semiconductor fab tools. Classified under HTS 8482.10.5012 as other linear ball bearings for their specialized linear load handling.
NSK NH/NS Series Linear Guide Blocks
NSK NH/NS linear guide blocks pair with rails for high-speed, low-friction linear motion using ball circulation technology, essential in semiconductor photolithography stages. HTS 8482.10.5012 covers these as linear ball bearings optimized for uni-directional or bi-directional loads.
Hiwin HGH20CA Linear Carriage Block
Hiwin HGH20CA is a heavy-load linear ball bearing block with equal load in all directions, used in semiconductor wafer polishing equipment for precise table motion. Falls under HTS 8482.10.5012 as a complete linear bearing unit.
IKO Super Thin Linear Roller Bearing SR25
IKO SR25 super thin linear bearing uses needle rollers caged between raceways for space-constrained applications like semiconductor probe cards. While primarily roller-type, certain ball variants fall under HTS 8482.10.5012 as linear bearings.
