よくあるご質問(FAQ)

質問: What is the allowable temperature range of your ballscrews?
回答: The standard allowable temperature range is 0°C to 80°C.
質問: Can I buy the nut or shaft separately?
回答: No, we do not offer the nut or shaft separately. The ball bearings inside the nut are sized to match each shaft to ensure proper clearance ranges.
質問: What grease is used for your Ball Screws?
回答: The standard grease is Alvania Grease S2 made by Showa Shell Sekiyu K.K. It is an EP 2 lithium bearing grease.
質問: What is the recommended lubrication schedule?
回答: As a rule of thumb, 100 km of linear travel is a good starting point for determining a lubrication schedule. The final schedule should be determined by the customer based on their specific appliation details (load, speed, temperature, contamination ,etc) and application experience.
質問: Do you offer food grade grease?
回答: No, we do not offer food grade grease as a standard option for ball screws.
質問: What does the dynamic load rating mean?
回答: The basic dynamic load rating (Ca) is used to calculate the service life of a ball screw in motion with its ball screw nut under an axial load. The basic dynamic load rating Ca means an axial load at which 90% of a group of identical ball screw units independently operating under the same conditions achieve a rated load of 10^6 revs (1 million revolutions) without causing flaking.
質問: Do you offer screws with right and left hand threads?
回答: We do not offer right and left hand threads on the same shaft as standard. For large volumes, it may be a custom option. Please contact engineering with application details.
質問: What is the difference between pitch and lead?
回答: The pitch is the distance between successive crests of the thread of a screw. The lead is the axial distance traveled by a screw in one turn.
質問: How does temperature increase affect the Ball Screw?
回答: An increase in the screw shaft temperature of 1°C expands the shaft by 12μm per meter. For this reason, although the lead of the Ball Screw is machined to a very high degree of precision, the thermal deformation caused by a temperature increase may reduce positioning accuracy.
