HJG-DZ
Rectangle Roller Block
Rectangle block for the HJG-DZ roller guide. Songju’s published roller guide is a recirculating roller rail, code HJG-DZ, not a separate non-recirculating crossed-roller way.
HJG-DZ Rectangle Block (ZC)
The HJG linear-motion catalog specifies roller guidance as HJG-DZ. Rollers recirculate in the block. The catalog does not list a separate crossed-roller cage series. This page describes the rectangle block, code ZC, including the extended ZCL where the size table shows it.
Nominal sizes in the HJG-DZ tables run 35, 45, 55, 65, 85, and 100 mm. Sizes 35–65 mm sit in the published 15–65 mm portfolio range; 85 and 100 mm are additional sizes in the specification tables. Preload is H1, H2, or H3. Accuracy grades are P, H, and SP. Flange blocks are on the HJG-DZ flange page. Dimensions are in the catalog PDF.

Rollers provide the high contact rigidity described for HJG-DZ.
Vibration absorption
The catalog lists strong vibration absorption and high load capacity.
Preload H1–H3
Light, medium, or heavy preload for the duty of the axis.
