AI Thread Summary
The discussion centers on the thread designation for G and G1 holes on an HBM force transducer, specifically a 125kN model. The user is confused about the specified M33x2 thread pitch, questioning its suitability given that the standard coarse pitch for M33 is 3.5mm. They express concern about the difficulty of finding compatible attachments for these fine pitch holes. While some participants mention the use of ISO Metric Course threads, there is uncertainty regarding the fine pitch specifications for M33. The user seeks clarification before proceeding with the purchase to avoid compatibility issues.

Afternoon everyone,

I am slightly confused...

Basically, i will be purchasing a force transducer from a company called HBM.

Now, on their data sheet it shows that there are two tapped holes either end of the transducer, designated by G and G1.

I am using a 125kN transducer, and for G and G1 it gives the following (also see attached screen shot and zoom into the bottom table):

G:M33x2−4H 35.6 deep.

G1:M33x2−4H 35.6 deep.

Now i understand what each number and letter is supposed to denote, but the pitch value of 2mm seems so small. If you notice on the table, all thread pitches are 2mm - even for the M16 to M72 threads that are listed in the table?

Obviously for a course pitch the the pitch for an M33 is 3.5mm, but the fine pitch series doesn't mention anything?

I don't want to purchase the load cell if it will be an impossiible task to get the thread on the attachments - that will screw into the M33 holes.

I also know that the HBM are originally a German company, so maybe they use an odd designation.

I have contacted the UK tech support team and they don't know.

Can anyone please help me?

Have a great weekend,

mech King


Genrally we tend to use ISO Metric Course threas in my industry

Machinery's lists all of those as being part of the M profile as per ASME B1.13M. I can't say that I am familiar with them because I don't use metric threads very often. I don't even have the spec on hand to look at.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
