Telescopic spring cover specification 1. Dimension definition： Parameters F D1 d1 D2 d2 d3 S Lmax Lmin Description ball screw outer diameter inner linear outer diameter inner linear inner diameter spring outer diameter spring inner diameter Outer linear inner diameter stroke maximum extension length minimum compress length How to choose a telescopic spring cover? A looser telescopic spring cover has a better performance in preventing from the dust and it is better for machine working process. Especially for horizontal ball screw occasions, looser telescopic spring may be your better choice. 1. Define the ball screw outer diameter (F). (Unit in mm) 2. D1 = d2-1 (Unit in mm) 3. d3 = D2+2 (Unit in mm) 4. d1 = F+3 (Unit in mm) 5. d2 = F+10 (Unit in mm)
