Före inbyggnad, mät upp bussningens nominella "L"-mått, lägg därefter till längdutvidgningen så att bussningens spets ligger exakt vid intagspunkten i uppvärmt tillstånd. 3 2 8 L max 1,5 0.25-0.5 R=1 ØD Ø(D+4) Gate on runner or on surface not perpendicular to bushing. Increased temperature in the front end of the bush due to reduced heat loss. more 2.03.2 Date: 030930, © LKM Heatlock Co Ltd
