[THK] — JR-A/B/R Structural Rail LM Guide Block (4-Direction Equal Load)

Family ID: THK-JR-ABR

Structural rail type LM Guide. A type: flange tapped / B type: flange through-holes / R type: narrow width tapped. 4-direction equal load with 45° ball contact angle. Rail center is thin — absorbs parallelism error between two rails. High bending rigidity rail cross-section usable as structural member.
