# What factors into the high cost of transmission components? [closed]

I've been shopping around for gears, pulleys and other transmission components for building a milling machine over the past few weeks. Many of these parts are so rudimentary and ubiquitous, yet the prices are very high. A ribbed pulley, for instance, about 3 inches in diameter often sells for over $30 online. Many of these parts are either stamped or cast, making them cheap to manufacture. What factors into the cost of these components? • Rants in disguise do not make for good Q&A. And yes, you're missing out on a number of variables that dictate the retail price of a replacement part. I'm not saying that the example you cited is reasonable, but rather that there are many variables at play. – user16 Jul 8 '15 at 21:45 • I suggest to re-edit your question not looking rant any more.

Low volume may allow "what the market will bear" pricing but in any sort of volume Chinese prices asymptote to about 50% or ludicrously low.look at eg here, find sellers with MOQ = 1 and find price. You CANNOT be sure of$ based on what it says there. You need at least to look at their sites. | Jul 9 '15 at 13:42
• Also try here - use boxes for MOQ=1 free shippung and sort by price ascending. Set min \$ to get rid of small stuff etc. Jul 9 '15 at 13:42
