General Information

Ready-to-install plastic plain bearing bushes

Dry running possible at low sliding speed

Design as bushes without flange or as flange bushes

For shaft diameters till 60 mm

For low speed unlubricated or medium speed lubricated

Very low-wear with smooth shafts and sufficient lubrication

Noise-absorbing and vibration-damping

After press-fitting into a bore H7, the inside diameter tolerance is approx. E10

Material: PA 6.6 (polyamide 6.6, die cast)

pv-value: up to 0.34 MPa x m/s, depending on sliding speed and bearing temperature

Dyn. bearing load: max. 18 N/mm2, depending on sliding speed and bearing temperature

Max. peripheral speed: 2 m/s, depending on the surface pressure

Temperature range: -40 to +80 °C

Bearing clearance: 0.01 mm per mm shaft-Ø

Shaft (recommended): tolerance h9, surface finish Ra max. 1.3, strength min. 650 N/mm2
