In theory it would help the belt run smoother by allowing the ribs of the belt mate with the teeth on the pulley versus rolling over the flat face of the stock pulley. After receiving these, I inspected and tested the smoothness of the bearings. If you take the tip of a small touch paint brush or even the tip of a pen, you can feel the smoothness. 4 out of 5 were rough, not binding but noticeably not as smooth as the used original ones I just removed. I applied bearing oil(RC car specific) to bearings and worked it in, that cleaned up about half of them, the others it didnt make a difference. I then installed them on the X and Y axis belt tensioners. This is where you will notice they do Not fit well on the Ender3V2. These pulleys measure aprox 12.2mm on the diameter(its actually smaller than that since the belt rides in the teeth of the pulley) and aprox 8.5mm(1.5mm narrower than stock pulley, which will allow the pulley to walk side to side) from outer flange face to face. On the E3V2- the X pulley measures 16mm dia and 10mm wide, Y pulley measures 13mm dia and 10mm wide. Also the bore of the pulley is M3(E3V2) versus M5 on these pulleys. Once you combine all the differences in sizes and actually install it, your belts will rub on the aluminum 20x20 bars, because of the decreased daimeter of the pulleys. So I am giving them a 3/5 stars due to the poor quality of the bearings. They will work as a last resort, so I will hold them for spares, just in case. ### ⭐⭐⭐ 3.0 out of 5 stars Edit to review (Bearings badly pressed in) *by J***R on Reviewed in the United States on March 14, 2019* Edit to my first review: after receiving new bearings to replace the ones in these idlers, I found that the bearings themselves are defective and POSSIBLY may not be a result of bad pressing, therefore, I am increasing from one star to three as they are pretty rough, but may not be the fault from assembly. The pulleys themselves are good and concentric.Stick in a shaft and rotate, feels like its grinding, its the same with all 20 that I purchased.Its quite obvious that they were pressed into the pulley from the inner race and not the outer. Pressing from the inner race puts all the force onto the balls causing flat spots on the balls and the race resulting in rough rotation.On the other hand, the machining is pretty nice, but the poor assembly is pretty sad to me.I would NOT recommend buying these, thoughtful assembly by the manufacturer is apparently not a concern.Unfortunately, I will now have to somehow remove the bearings and replace them with new ones, as i'm sure replacements will result in the same situation. :( ### ⭐⭐⭐⭐ 4.0 out of 5 stars Worked fine for me *by G***D on Reviewed in the United States on March 5, 2018* Not as bad as I feared from other reviews. Ordered 10 to make sure I would have enough "GOOD" ones due to other reviews stating bad bearings. Mine all came with good bearings that are smooth and work just fine. I wonder if others are tightening the axle screws down too much causing problems with side load on the bearings making them grind? --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/47563565-wangdd225pcs-gt2-timing-belt-idler-pulley-20-teeth-20t-aluminum](https://www.desertcart.tn/products/47563565-wangdd225pcs-gt2-timing-belt-idler-pulley-20-teeth-20t-aluminum) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
