The accurate bore size ensures no wobble or offset during high-speed rotation, delivering stable running performance and effortless bolt-on replacement for most standard mounting shafts. - 45 MM OD: 45 mm outer diameter pulley body provides optimal contact area for wire rope traction and linear sliding. Balanced wheel size reduces per-unit pressure, minimizes abrasion, and extends the overall service life of both the pulley and matched cables. - 6 MM GROOVE WIDE: Built with 6mm wide and 3mm deep u-groove with standard radian structure, firmly locks wire ropes in position. Effectively prevents rope slipping, derailment and friction damage, ensures smooth, safe lifting and sliding operation for long-term continuous use. - DOUBLE SHIELDED: Pulleys with a ball bearing are easier to turn than pulleys without a bearing. Pulleys with double shielded bearings block out dust and other contaminants. These pulleys are used to assist with horizontal pulling or to guide a rope, wire or cable. - POM TREAD: Outer wheel made of polyoxymethylene with outstanding abrasion and compression resistance, hard to crack or deform under frequent sliding. Integrated bearing steel inner bearing ensures smooth rotation, the elastic POM coating buffers collision, avoids scratching guide rails, reduces operating noise and greatly prolongs roller service life, with max 30KG single pulley load capacity. - WIDE APPLICATIONS: Ideal for wire rope sheave traction, mechanical power transmission, sliding track systems, garage sliding doors, furniture hardware, 3D printer guide mechanisms and various DIY industrial mechanical equipment. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D8RP4KZ | | Bearing Number | 608ZZ | | Bearing Type | Ball Bearing | | Best Sellers Rank | #232,254 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,462 in Deep-Groove Ball Bearings | | Brand Name | CNBTR | | Compatible Lubricant | Grease | | Customer Reviews | 4.4 4.4 out of 5 stars (556) | | Included Components | 4 x POM Pulley | | Item Dimensions | 1.77 x 0.45 inches | | Item Highlight | Width: 11.5mm | Groove Width: 6mm | Groove Depth: 3mm | For Sliding Doors, Windows, 3D Printers, and Sliding Equipments | | Item Thickness | 11.5 millimeters | | Item Weight | 3 g | | Manufacturer | YQLTD | | Material Type | POM + BEARING STEEL | | Model | M6180521112 | | Number of Items | 4 | | Number of Packs | 1 | | Outside Diameter | 45 millimeters | | Part Number | M6180521112 | | Specification Met | 608zz | | Unit Count | 4 Count | ## Product Details - **Bearing Number:** 608ZZ - **Brand:** CNBTR - **Item Weight:** 3 g - **Item dimensions L x W x H:** 1.77 x 0.45 inches - **Material:** POM + BEARING STEEL ## Images ![4Pcs U-Groove POM Pulley | 8mm BORE | 45mm OD | 167KG Load Capacity - Image 1](https://m.media-amazon.com/images/I/413tDOUCRPL.jpg) ![4Pcs U-Groove POM Pulley | 8mm BORE | 45mm OD | 167KG Load Capacity - Image 2](https://m.media-amazon.com/images/I/51mOaH-XggL.jpg) ![4Pcs U-Groove POM Pulley | 8mm BORE | 45mm OD | 167KG Load Capacity - Image 3](https://m.media-amazon.com/images/I/415V6-D64YL.jpg) ![4Pcs U-Groove POM Pulley | 8mm BORE | 45mm OD | 167KG Load Capacity - Image 4](https://m.media-amazon.com/images/I/41+P3+iJJCL.jpg) ![4Pcs U-Groove POM Pulley | 8mm BORE | 45mm OD | 167KG Load Capacity - Image 5](https://m.media-amazon.com/images/I/41Z+Jxn4AFL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - CNBTR 4PCS U-Type Pulley Wheel 0.31X1.77X0.45inches U Groove Bearing for Doors and Windows with Steel Bearings 8mm Shaft Hole 45mm - 4Pcs U Groove Pulley Wheel U-Groove Roller Guide Pulley Rolling Bearing Roller Wheel 8x45x11.5mm for Bicycle Accessories Pulleys Equipment - uxcell 4pcs U Type Groove Pulley Nylon Guide Rolling Bearing 5x25.5x8.5mm U Groove Roller Wheel for Door Window, Blue --- ## 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/91518917-4pcs-u-groove-pom-pulley-8mm-bore-45mm-od-167kg](https://www.desertcart.tn/products/91518917-4pcs-u-groove-pom-pulley-8mm-bore-45mm-od-167kg) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-11*
