More than double the 18 kg body in the same family. That mass absorbs interrupted cuts and also means the vise no longer moves by hand between machines: plan a hoist, and check the table load rating before assuming it can sit at the end of a small table.
FIG. / PRODUCT VISUAL / 6 VIEWSGT150 / GT175 / GT200 modular vise, 38 kg
A family of modular machine vises in 20CrMnTi with jaws at HRC 58-62, jaw-face parallelism of 0.005 mm / 100 mm and squareness of 0.005 mm. The range covers QKG and GT100 at 18 kg, and GT150, GT175 and GT200 at 38 kg, all hand-driven for CNC machining centres.

GT150, GT175 and GT200 are three jaw widths under one record with one 38 kg figure. The weight cannot be identical across all three, so confirm the size and its actual mass in the quotation rather than reading 38 kg as a per-size value.
The family accuracy, unchanged by size. Larger jaws make it harder to hold, not easier: the same 5 µm now spans a longer face, so temperature and clamping force matter more than on the 100 mm body.
Manual drive, machining-centre use. The larger opening means more overhang on the moving jaw, so heavy side loads belong on a fixture rather than on the vise alone. Hard jaws mark finished faces at this hardness.
Which sizes are covered?
GT150, GT175 and GT200 under one listing.
How heavy?
38 kg on the record, for the family rather than per size.
What accuracy?
Parallelism 0.005 mm / 100 mm, squareness 0.005 mm.
