10Pcs Lead Screw Lock Collar Axis Sleeve 304 Stainless Steel Bore 2-12mm for CNC Milling Machine Mechanical Repairs

### Key Advantages 1. Unbeatable Structural Strength: Manufactured with high-grade solid steel, this shaft lock ring offers outstanding resistance to wear, impact and shape distortion, guaranteeing long-lasting stable function even when used in high-load mechanical working environments. 2. Broad Size Compatibility: It comes in 9 commonly used inner diameter sizes (2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm), fitting nearly all mainstream shaft diameters available on the market, so you don't need to pay extra for custom sizes for regular applications. 3. Secure Locking Design: The pre-drilled fixed screw holes on the steel ring let you tightly fasten it to the shaft to avoid unintended axial displacement, which effectively enhances the stability and safety of your mechanical assembly work. 4. High-Precision Craftsmanship: Every surface of the ring goes through precision grinding processing, so it has minimal dimensional tolerance and a super smooth contact surface. It fits seamlessly with shafts and supporting parts, reduces installation gaps and elevates overall transmission accuracy.
