Description

Plain bearings cylindrical Material: Base material, steel. Intermediate layer sintered bronze. Bearing surface PTFE. Version: Steel galvanized. Note: Maintenance-free rolled composite steel plain bearings particularly suitable for dry running. Also highly suitable for lubricated applications (oil lubrication). Very low wear and friction, no stick-slip effect. Suitable for rotary and oscillating movements, high chemical resistance, low water absorption. Technical data: Static load: max. 250 N/mm² Dynamic load: max. 140 N/mm² Friction coefficient, dry: 0.03 to 0.20 Sliding speed, dry: max. 2 m/s Sliding speed, oil lubricated: max. 5 m/s Thermal conductivity: 42 W(m*K)-1 Thermal expansion coefficient: 11*10-6 K-1 Temperature range: -195°C to +280°C Assembly: The use of a suitable press mandrel is recommended to avoid damaging the bearing surface. The butt joint must be opposite the load zone. The bearing has an interference fit after installation. Gluing is possible but not required. Tolerances: Housing: Recommended tolerance H7. Surface finish Ra 0.8 to 1.6. Chamfer (press-in side 0.8 to 1.2 x 15°). Shaft: Recommended tolerance h8 to f7. For applications at a low speed and small loads drawn shafts with h9 can also be used. Shaft surface Ra 0.4 to 0.8 (preferably ground shafts) for drawn shafts Ra 1.6 to 3.2. Drawing reference: 1) Butt joint
