Material:Base material, steel.Intermediate layer sintered bronze. Bearing surface PTFE.Version:Steel electro zinc-plated.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/mm²Dynamic load: max. 140 N/mm²Friction coefficient, dry: 0.03 to 0.20Sliding speed, dry: max. 2 m/sSliding speed, oil lubricated: max. 5 m/sThermal conductivity: 42 W(m*K)-1Thermal expansion coefficient: 11*10-6 K-1Temperature range: -195°C to +280°CAssembly: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
