THK HSR30CA1SS(GK) is an LM Guide carriage block, four-way equal-load, full-complement ball, for a 28 mm wide HSR size-30 LM rail. Block only, no LM rail. GK series: interchangeable block-only and rail-only line. Assembly height 42 mm, block width 90 mm. Unit Quantity: 1 Pc.
HSR — THK four-way equal-load full-ball LM Guide series.
30 — size, 28 mm wide rail.
CA — flanged block with tapped mounting holes, mountable from the top or the bottom.
1 — THK coding field for the number of LM blocks used on the same rail.
SS — end seal, side seal and inner seal. (DD is double seal; UU is end seals only.)
GK — interchangeable block-only and rail-only series; blocks and rails combine freely with the same model number.
