HGW15CC Flange Linear Guide Block — 15 mm, Interchangeable
The HGW15CC is a 15 mm flange-type heavy-load block for axes where the carriage bolts down from above and below. It uses the HG rail profile, so it fits existing HGR15 rails. Interchangeable blocks are supplied in Z0/ZA preload and C/H/P accuracy.

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
HGR15 rail is cut to order from 100 mm. See rail options.

FAQ
| Is HGW15CC interchangeable with HGH15CA? | They share the same HGR15 rail, but the block bodies differ: HGW is flange type, HGH is square type. Choose by how the carriage is bolted. |
| Can the block and rail be bought separately? | Yes, in Z0/ZA preload and C/H/P accuracy. SP/UP accuracy and ZB preload are supplied as a matched set only. |
| Which rail length do I need? | Use L = (n − 1) × P + 2 × E with P = 60 mm and E = 20 mm for HGR15. |
