Engineers, makers, and automation builders who need a dependable close loop synchronous belt in compact perimeter sizes will find exactly what they need here — available in six perimeter options and two widths, ready to drop into your existing HTD 3M pulley system.\u003c\/p\u003e\n\u003cp\u003eEach listing is for one (1) HTD 3M close loop rubber timing belt. The belt body is made from neoprene rubber with a nylon-reinforced tooth face and a fiberglass or steel cord tensile layer for minimal stretch. Available perimeters range from 198mm (≈7.8\") to 231mm (≈9.1\") — specifically 198mm, 201mm, 204mm, 213mm, 228mm, and 231mm — in widths of 10mm (≈3\/8\") and 15mm (≈19\/32\"). The HTD 3M tooth profile features a 3mm pitch with a rounded curvilinear tooth form designed for smooth, high-torque engagement.\u003c\/p\u003e\n\u003cp\u003eThese HTD 3M synchronous belts are widely used in desktop 3D printer drive systems (extruder and axis drives), small robotic arm joints, DIY CNC router axis drives, and light industrial automation conveyor loops.
