| Part Category | Part Name | Material Recommendation | Specifications and Models (National Standard / Example) | Core Dimension Parameters (Example, Unit: mm) | Key Performance Parameters | Applicable Scenarios | Remarks |
| General Support Type | General Shaft Sleeve | - Gray Cast Iron (HT200/HT250) - 45# Steel (Quenched and Tempered) - Tin Bronze (ZCuSn10Pb1) | GB/T 2889 (General Specification for Shaft Sleeves) Example: φ20, φ40, φ60 | Inner Diameter (d): 20 (H7), 40 (H7), 60 (H7) Outer Diameter (D): 30 (H8), 55 (H8), 75 (H8) Length (L): 30, 50, 80 Wall Thickness (t): 5, 7.5, 7.5 | Hardness: HB180-220 (HT200), HB220-250 (45# quenched and tempered) Compressive Strength: ±250 MPa (HT200), ±600 MPa (45# steel) Temperature Resistance: ±300°C (cast iron), ±400°C (45# steel) | Low speed (≤1500 r/min), light/medium load applications, such as agricultural machinery gearboxes and general machinery drive shafts | Interference fit (H7/r6) is used for installation, and assembly oil is required; calcium-based grease is used for normal operating conditions. |
| Precision wear-resistant type | Precision steel sleeves | - 20CrMnTi (carburizing steel) - GCr15 (bearing steel) - 38CrMoAlA (nitriding steel) | GB/T 18324 (Specification for Precision Bushings) Example: φ15, φ30, φ50 | Inner Diameter (d): 15 (H6), 30 (H6), 50 (H6) Outer Diameter (D): 25 (H7), 42 (H7), 65 (H7) Length (L): 25, 40, 60 Wall Thickness (t): 5, 6, 7.5 Coaxiality: ≤0.005mm (overall length) | Hardness: HRC58-62 (20CrMnTi carburized), HRC60-64 (GCr15 quenched) Wear Resistance: Wear Loss ≤0.01mm/100h (oil lubricated) Surface Roughness: Ra ≤0.4µm (inner bore) | High-speed (1500-8000 rpm) and heavy-load applications, such as machine tool spindles, motor shafts, and hydraulic pump shafts | Inner bore requires fine grinding; 20CrMnTi carburized layer depth 0.8-1.2mm, 38CrMoAlA requires nitriding; use high-speed extreme pressure grease. |
| Corrosion-resistant type | Corrosion-resistant bushing (steel base) | -304 stainless steel-2Cr13 (martensitic stainless steel)-copper alloy bushing (ZCuAl10Fe3) | GB/T 2889 (corrosion-resistant type) Examples: φ12, φ25, φ45 | Inner diameter (d): 12 (H7), 25 (H7), 45 (H7) Outer diameter (D): 20 (h8), 35 (h8), 55 (h8) Length (L): 20, 35, 50 Wall thickness (t): 4, 5, 5 | Hardness: HB140-180 (304), HRC28-32 (2Cr13) Corrosion resistance: Neutral salt spray test ≥48h no rust Temperature resistance: -200~600℃ (304) | Humid and corrosive environments, such as marine equipment, chemical machinery, food machinery | 304 material is not suitable for strong acidic environments; copper alloy bushings need to be regularly lubricated to prevent dry friction |
