Received this bearing last week for my 3D printer upgrade. The fit on the 20mm rod is perfect and it runs very smooth. Packaging was decent. Slightly expensive than local market but quality justifies it.

This is a solid bearing. Installed it on a 20mm hardened shaft and the movement is quiet and smooth. No lateral play at all. Great for CNC and print applications. I would recommend it without hesitation.

Review by Tawsif Tahsin
অটোমেশন প্রজেক্টে লাগানোর জন্য নিয়েছিলাম। চেহারায় ছোট হলেও কাজে দারুণ নির্ভরযোগ্য। ২০ মিমি রডের সাথে ফিটিং একদম নিখুঁত, চলাচলে কোনো কাঁপুনি নেই। এখন পর্যন্ত সন্তুষ্ট।

Review by Nabil
২০ মিমি বোরের এই বেয়ারিংটা আমার প্রিন্টার মেশিনে ব্যবহার করছি। মসৃণ গতি আর নির্ভুলতা দুটোই ভালো। বডি মজবুত এবং ফিনিশিং নিয়ে খুশি। প্যাকেজিং ভালো ছিল, কোনো ক্ষতি হয়নি।

Review by Sharar
Bought a handful of these for an automation project. They work exactly as expected. The sleeve is sturdy and the balls roll smoothly. Only minor issue is the price, but the quality is worth it. Very satisfied.

Review by Ekramul Haque
আমার CNC রাউটারের জন্য কিনেছিলাম। ২০mm শ্যাফটে একদম মানানসই, স্লাইডিং খুবই মসৃণ। কোনো শব্দ বা ঝামেলা নেই। ডেলিভারিও দ্রুত পেয়েছি। এই দামে এমন মানের পণ্য পাব বলে ভাবিনি।

Sourav's review emoji-happy
Review by Sourav
Using this LM20UU on my CNC machine build. The bearing moves smoothly along the shaft and there is no play in the housing. It feels well built. I have tried other bearings before and this one performs much better for the price.
