Cheap as they are I'll not go through the trouble of a return but order more and perhaps end up with a couple of spares. I will, however, look for another seller. ## Frequently Bought Together - HiPicco Linear Motion Ball Bearing Slide Block, SCS20UU 20mm Pillow Block Closed Linear Bearing Aluminum Bushing Linear Rail Support Guide Shaft Bearing for CNC 3D Printer Parts 4 Pack - 1 PCS 20mm x 400mm (0.79 x 15.75 inches) Vigorous Linear Motion Rod, Case Hardened Chrome Shaft Linear Rail Rod Shaft for 3D Printer, DIY, CNC - Metric h8 Tolerance - HiPicco 4pcs SHF16 Aluminum Linear Rod Rail Shaft Support 16mm Linear Motion Guides for CNC 3D Printer --- ## 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.vn/products/516778533-linear-motion-ball-bearing-slide-block-scs20uu-20mm-pillow-block](https://www.desertcart.vn/products/516778533-linear-motion-ball-bearing-slide-block-scs20uu-20mm-pillow-block) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-17*
