Product catalog summary

Specifications:
The document outlines the specifications for guide bushings made from bronze with graphite (SP2) and solid lubricant (GR-1). It includes details on operation range, physical properties, and material composition.

Operation Range:
- Lubricant Type: No lubrication or regular lubrication with grease.
- Environment Condition: Suitable for atmospheric conditions.
- Max Allowable Load: 100 N/mm² without lubrication, 30 N/mm² with grease.
- Max Allowable Sliding Speed: 15 m/min without lubrication, 200 m/min with grease.
- Max Allowable PV Value: 150 N/mm²·m/min without lubrication, 150 N/mm²·m/min with grease.
- Temperature Range: Up to 150°C for regular lubrication, up to 300°C without lubrication.

Physical Properties:
- Specific Gravity: 7.9 g/cm³
- Hardness: 210 HB or more
- Elongation: 12% or more
- Tensile Strength: 755 N/mm² or more
- Linear Expansion Coefficient: 1.9 ×10−5/°C

Design and Tolerances:
- The document provides detailed dimensions and tolerances for various catalog numbers, including diameter, length, and tolerance after press-fit.
- Mating post tolerance is specified as d8 for general use with high load, e7 for light load, and f7 for high precision.

Additional Characteristics:
- The bushings can be used in atmospheric and fresh water conditions.
- They perform well under high load and low-speed operations.
- Special embedding specifications for solid lubricant are required for temperatures above 150°C.

Recommendations:
- For high-temperature applications, contact the supplier for specific embedding specifications.
- Ensure proper chamfering and tolerance adherence during installation.
