10Micron GM4000 Counterweight 20 kg

10Micron GM4000 Counterweight 20 kg

This 20 kg stainless-steel counterweight is the maker’s 10M4083 accessory for the GM4000 / AZ4000 mount family. It has a satin finish and a hand-operated tightening screw for securing its position on the shaft.

Shaft compatibility

10Micron lists this part for GM4000/AZ4000, but its accessory-page bore conflicts with the mount technical sheets. A numerical bore is therefore not stated here as verified.

Balancing arrangement

Choose the quantity and shaft position for the actual optical tube, cameras and accessories. The counterweight is a balancing component and does not increase the mount’s rated instrument payload. This product is one weight, rather than a complete counterweight set.

Compatibility notes

Exact mass, manufacturer SKU and mount-family accessory matched. Quantity and placement depend on balancing the complete instrument train. The accessory page says a 50 mm bore, but both GM4000 and AZ4000 technical sheets specify a 60 mm shaft. No bore value is assigned; the contradictory accessory-page number is not repeated as a verified fit dimension.
