Description Lionsele® B1 bearing strip, with a very low coefficient of friction, is used as a tape-type bearing material within a hydraulic system when the designer needs to accommodate relative movement between two surfaces.
This plain rectangular bearing strip of bronze-loaded PTFE provides cost-effective and easy-to-use alternative to traditional materials such as phosphor-bronze or lead.
Special features
Self-lubricating to provide low dynamic and breakout friction.
Suitable for high speed applications.
High fatigue-strength material that provides long service life and damping of mechanical vibrations to reduce downtime.
Versatile and easy to assemble.
Typical applications Often used in conjunction with 'compact' piston head seals in hydraulic systems to eliminate metal-to-metal contact and other problems associated with offset pistons.
Operating capabilities
Maximum bearing stress at RT (static duty): 25N/mm².
Maximum bearing stress at RT (dynamic duty): 12N/mm².
Temperature range: -60°C to +150°C (or up to +200°C with severely restricted load carrying capacity on dynamic duties).
Maximum recommended relative velocity: 5.0m/s.
Materials of construction Bronze-loaded PTFE.
Media capabilities Chemically compatible with most commonly used hydraulic fluids.
How supplied In length form, machined split or machined endless. For bearing strip selection data, please contact your nearest James Walker office.
