Characteristics and performance
The Hallite 87 bronze-filled PTFE bearing strip is designed to provide an extremely effective, hard wearing, and easy-to-use bearing solution for lubricated or non-lubricated reciprocating, oscillating, and slow rotary movement applications. Hallite recommends using the Hallite 87 in light-duty applications and particularly for small diameters where the flexibility of the strip makes installation into a groove easier.
The low friction PTFE material reduces ‘stick slip’ between moving parts. The material is compatible with hydraulic mineral oil, lubricating oil, water based and synthetic fire resistant fluids and lubricating grease. It has excellent heat resistance and strength to resist creep. Although the material is rated at 200°C (390°F), the recommended maximum temperature for bearing applications is 60°C (140°F).
