dadaji ke project me lagaya
my father wanted to build a small automated gate mechanism for our backyard farm setup. bought this because of the right angle 90 degree offset design which saved a lot of space in the tight enclosure. aluminum housing feels very sturdy and sealed properly so oil won't leak out.

solid build quality
box arrived a bit crushed on the corner by the courier guys which gave me a mini heart attack, but thank god the part inside was totally safe. fitted this 20 to 1 worm gearbox for my automation setup and it works smooth. heavy duty stuff.

kaam chalau acchi cheez hai
sach batau toh mujhe zyada umeed nahi thi ki yeh itna heavy load sambhal lega, bas ek chote conveyor project ke liye mangwa liya tha. par fit karne ke baad torque kaafi sahi mil gaya. bas thoda sa sound karta hai chalte waqt, baaki sab badhiya hai.
