Specifications:
The document outlines the specifications for metal sliding materials, specifically focusing on bronze with graphite (SP2) as the base material. The dimensions and tolerances for various components are provided, including diameter, width, and length measurements. The sliding direction is specified, and the material includes a hatched area for solid lubricant (GR-1).
Operation Range:
The operation range is defined by the lubricant type and environmental conditions. For GR-1, no lubrication is required in atmospheric conditions, with a maximum allowable load of 100 N/mm², sliding speed of 15 m/min, and PV value of 150 N/mm²•m/min. The temperature range is from -50°C to +300°C. With regular lubrication (grease), the load increases to 30 N/mm², speed to 200 m/min, and temperature range narrows to -50°C to +150°C.
Physical Properties:
The material has a specific gravity of 7.9 g/cm³, hardness of 210 HB or more, elongation of 12% or more, tensile strength of 755 N/mm² or more, and a linear expansion coefficient of 1.9 ×10−5/°C.
Order and Mounting Information:
Catalog numbers are provided for ordering, with specifications for bolt positions and mounting bolts. The document lists various sizes and quantities for bolts, indicating the flexibility in ordering different dimensions.
Special Requests:
The document notes that special parts can be requested or ordered. It also mentions that for high-temperature applications (150°C or more), the embedding specification of solid lubricant differs, and further details can be obtained by contacting the supplier.
