Applications Widely used in gear shafts, motor shafts, short support shafts, shaft pocket models, and miniature axles. Suitable for model planes, model ships, and model cars, providing dependable shafts and axles for hobby projects and smallscale assemblies. Benefits and features precision machining ensures accurate fits in tight tolerances. Strong, durable material that resists wear and corrosion to support repeated use. Surface is smooth and easy to shape, with no cracks, facilitating easy work and finishing. Use scenarios Building a model plane or model car that requires precise drive shafts or axles for smooth rotation. Creating miniature axles or shaft pockets in RC boats or ships for reliable propulsion and alignment. Prototyping small gear assemblies or motorshaft connections in hobby projects and modelmaking. Storage and care During storage, apply a light coat of oil and minimize air exposure to reduce rust risk. The surface remains smooth for shaping, and the rods stay from cracks.
