■Outer cylinder strength of flanged oil free bushings

■Test conditions: 1. Testing instrument: universal tensile compression testing machine
2. Bushing: copper alloy
3. Shaft: MISUMI's hardened g6 shaft

■Testing method

Load (*) and displacement measured when the shaft is deflected 1 degree
(*) Load at approx. 5% of the tensile strength of EN 1.0038 Equiv.
