MU Sliding Bearings
MU is a composite multiple-layer material used for manufacturing of dry self-lubricating sliding bearings.
The main parts composing this product are a loaded PTFE-based sliding layer (without lead), a sintered bronze layer and a low carbon steel support. The bronze layer guarantees a sound coupling for the self-lubricating mixture and allows good heat loss produced during operation. PTFE layer helps to achieve low friction coefficient and high wear resistance properties.
Shapes and Geometries
The shape and geometry of every Technymon Bearing is designed to ft its specifc application. We pay careful attention to the desired outcome, including crucial factors such as the clearance or interference ft with the mating components. The shape of bearing can vary greatly, with characteristics such as fanges, spherical shapes and holes being customized to enhance the overall performance of the application.
Applications
MU Sliding Bearings
Characteristics
- Good calibration/sizing assembly (zero-clearance)
- Fluids like oil or water permit higher PV factors
- Friction factor not affected by “stick - slip” effect
- Higher Chemical resistance to industrial fluids and gases (we recommend previous test for new application / project)
- Volume resitivity could be > 10Ω, but completely depends on surface contact in assembly
