Overview of RoHS Metal Sliding Materials

This document provides technical specifications and operational guidelines for RoHS-compliant metal sliding materials, focusing on copper powder sintered types and their physical and operational properties.

Material Specifications

• Material Type: Copper powder sintered (SO#220) with a hatched sintered area and SS400 base plate.
• Thickness: Minimum 1.2 mm, with some components specified at 20 mm thickness.
• Shape: Chamfered shape at both ends, with all-around chamfering.
• Dimensions: Various catalog numbers with dimensions W, L, W1, W2, L1, L2 specified for different product variants (SOX and SOXT types).

Operational Conditions

• Lubrication Conditions: No lubrication (atmosphere) and regular lubrication (grease) are considered.
• Maximum Allowable Load (P): 50 N/mm² without lubrication, 75 N/mm² with lubrication.
• Maximum Allowable Sliding Speed (V): 30 m/min without lubrication, 60 m/min with lubrication.
• Maximum Allowable PV Value: 100 N/mm² without lubrication, 150 N/mm² with lubrication.
• Operating Temperature Range: -40°C to 120°C.

Physical Properties

• Specific Gravity: Approximately 6.2 ± 0.3 g/cm³.
• Hardness: 70 to 90 HRM.
• Compression Strength (0.2% proof stress): 200 to 250 N/mm².
• Impregnation Ratio: 18% or more.

Product Variants and Dimensions

The document lists multiple catalog numbers for SOX and SOXT types with detailed dimensions (W, L, W1, W2, L1, L2) tailored for different applications. Dimensions range from widths of 25 mm to 300 mm and lengths from 15 mm to 250 mm, accommodating various sliding plate requirements.

Additional Notes

• Special orders and custom parts are accepted upon request.
• W1 and W2 dimensions apply only to SOX types with widths of 100 mm or more.
• The document emphasizes compliance with RoHS standards, ensuring environmental safety.
