HGW65CA Flange Linear Guide Block — 65 mm, Extra Heavy Load
The HGW65CA is the largest block in the HG range. It is specified on heavy gantries, large platens and presses where the 45 and 55 sizes run out of margin. Runs on the HGR65 rail.

Where this block is used
The flange body spreads the bolt pattern wider than a square block on the same rail, which helps when the carriage plate is thin or the load sits away from the rail centreline. Typical use is machine-tool tables, gantry beams and automation carriages that are bolted from both above and below.
Mounting: rails and blocks are bolted to machined faces. Rail bolts are tightened from the centre outwards in the sequence given in the catalogue, and running accuracy is checked with a dial gauge before the carriage is loaded. Lubrication is by grease nipple or oil port; the re-greasing interval follows load and duty cycle, so it is agreed with the customer rather than fixed on the datasheet.
Matching rail
HGR65 rail is cut to order from 100 mm. See rail options.

FAQ
| Is 65 mm a stocked size? | It is a production item rather than a stock item in most markets. Lead time is quoted per order. |
| What replaces a 65 mm block in a design review? | Nothing in the HG range — 65 is the top size. Below it, the 55 sits one step down with 114.44 kN. |
