Makers, workshop builders, and automation hobbyists who need a compact, low-friction wheel that stays quiet under continuous duty will find the 696ZZ U Groove Nylon Plastic Pulley a reliable drop-in solution.\u003c\/p\u003e\n    \u003cp\u003eEach pulley is built around a 696ZZ deep groove ball bearing core and fitted with a nylon outer wheel featuring a U-shaped groove profile. The overall dimensions are 6 mm bore × 27 mm outer diameter × 9 mm width (approx. 0.24\" × 1.06\" × 0.35\"). The nylon rim keeps rolling noise low while the steel bearing handles radial loads cleanly. Available in packs of 1, 4, or 10 to match your project scale.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include DIY 3D-printer filament guides, small conveyor and rope-tensioning systems, sliding door or drawer glide assemblies, and compact belt-drive automation rigs where a 6 mm bore U groove pulley wheel is required.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits 6 mm shafts or M6 bolts.
