ESPJ Sleeve Bearing
EPJ Plain Bearing
One main advantage of EPJ plain bearings is the combination of a low coefficient of friction in dry operation and the low stick-slip tendency. With a recommended maximum surface pressure of 35Mpa, ESPJ plain bearings are not suitable for
extreme loads.
* Low wear against different shaft materials
* Low coefficients of friction in dry operation
* Vibration-dampening
* Good resistance to chemicals
* Best material to use with soft shaft materials
* Very little humidity absorption
When to use it?
* For high speeds
* For highest wear resistance at low to medium pressures
* Low wear against different shafts
* Low coefficient of friction in dry operation
* Vibration dampening
* Good chemical resistance
* Best performance with soft shaft materials
* Very little humidity absorption
When not to use?

When not to use?
* When high pressures occur
* If temperatures are higher than +90℃
* When a cost-effective bearing for occasional movements is necessary
Tolerances and measurement system
The installation dimensions and tolerances of the Suntron plain bearings are a function of the material and wall thicknesses. For each material, the moisture absorption and the thermal expansion are imperative. Plain bearings with low moisture absorption can be designed with a minimal amount of tolerance. For wall thickness, the rule is: The thicker the bearings are, the larger the tolerances must be.
Assembly
Suntron bearings are press-fit bearings. The inner diameter adjusts only after press-fit in the proper housing bore with a
recommended tolerance. The before press-fit oversized dimension can be up to 2% of the inner diameter. In this manner, the secure
press-fitting of the bearing is achieved. Axial or radial shifts in the housing are also prevented.
