[ ! ]Cautions: Do not let the nuts overrun its stroke or remove the nuts from the screw shafts.
It may cause the balls to fall out or damage the ball recirculation parts.

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.
