Tolerance class for Plastic Gear

AI Thread Summary
The discussion centers on the need for a specific tolerance class chart for plastic gears, particularly 11e28 and 10e28. Users clarify that the previously shared chart pertains to hole and shaft tolerances, which differ from gear tolerances. A link to a relevant resource on gear tolerances is provided, but the initial poster seeks further assistance on the specific requirements for gear tolerances. There is also an inquiry about the purpose of this information, suggesting it may relate to testing equipment. The conversation highlights the distinction between different types of tolerance classes and the need for accurate information in gear design.

Hi Prassanna,
Thanks for the feedback.
The chart that you attached is Hole and shaft tolerance class.

But I'm requesting for Gear tolerance class.
Both are different.
Pls assist me if you have any info on gear tolerance class.

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?'

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...
