Overview of Metal Sliding Materials

This document provides detailed specifications and operational guidelines for various metal sliding materials, focusing on copper powder sintered types and related components.

Material Specifications

• Materials: Copper powder sintered (SO#220), S45C base plate, and sintered hatched areas.
• Thickness: Minimum 1.2 mm for sintered layers; 10 mm thickness for oilless slide plates.
• Hardness: Approximately 70 HRM.
• Compression Strength: 200-250 N/mm² (0.2% proof stress).
• Specific Gravity: Around 6.2 g/cm³.
• Impregnation Ratio: 18% or more.

Dimensional and Geometrical Data

• Various catalog numbers (e.g., UWM38Y48, TWX28, TWXT) correspond to specific dimensions (width, length, height) and tolerances.
• Key dimensional tolerances include ±0.01 to ±0.3 mm for lengths and widths, with chamfered edges (R2, R5, R10) and corner radii (C1.5) specified for durability and fit.
• Special bolt types (e.g., LCS-10-20 brazier head bolt) are used for mounting accessories.

Operational Parameters

• Maximum Allowable Load (P): 50 to 75 N/mm² depending on lubrication and environment.
• Maximum Sliding Speed (V): 30 to 60 m/min.
• Maximum PV Value: 100 to 150 N/mm²·m/min.
• Operating Temperature Range: -40°C to 120°C.
• Lubrication Conditions: Both no lubrication (atmospheric conditions) and regular grease lubrication are considered, affecting allowable loads and speeds.

Product Variants and Ordering Information

• Multiple product variants are available with different widths (W), lengths (L), and thicknesses, suitable for various sliding applications.
• TWX and TWXT series include oilless slide plates and sintered 2-hole types, with specific dimensional data provided.
• Bolts are not included with some models (e.g., TWX18).
• Custom orders and special parts requests are accepted.

Recommendations and Best Practices

• Ensure proper lubrication to maximize load capacity and sliding speed.
• Use specified mounting bolts and observe dimensional tolerances for optimal assembly and performance.
• Consider environmental conditions and temperature limits when selecting materials.
