THK SHW21CAN1SS(GK) is a caged-ball LM Guide carriage block, block only with no rail, from the wide low-profile SHW series. It runs on a 37 mm wide SHW size-21 rail. Four rows of balls at a 45° contact angle give equal load capacity in four directions. Assembly height: 21 mm. Block width: 68 mm. Unit Quantity: 1 Pc.
SHW — wide, low-profile caged-ball LM Guide series.
21 — size, corresponding to a 37 mm wide rail.
CA — flanged block with tapped holes, mountable from the top or the bottom.
1 — THK coding field for the number of blocks used on the same rail.
SS — end seal plus side seal.
GK — THK interchangeable block-only and rail-only series.
