Q. What is a linear motion system?

A.
The linear motion system is a generic term for equipment that allows heavy loads to move linearly with low drag and uses only a coefficient of friction of 0.005 for ball and roller units.


Q. Basic dynamic load rating and the basic static load rating difference?
A.
The basic static load rating is a limit of permissible load at standstill. The basic dynamic load rating is used to calculate the service life of the linear guide under load.


Q: What is the characteristic of the crossed roller collar?
One.
Cylindrical roller body was 90 degrees V-groove rolling surface through the spacer is perpendicular to each other cross-arranged. This design allows a single bearing can withstand radial, axial load and torque load in all directions, such as load. The retainer prevents the rollers from collapsing or rubbing against each other, so that an increase in the rotational torque can be prevented. As compared with the conventional type of iron plate retainer, the one-point contact phenomenon or lock-in phenomenon of the roller does not occur and a stable rotational movement can be obtained even when pressure is applied.


Q. Can I process inner ring and outer ring after purchase?
A.
Hardness is HRC58-64, buy and then have a certain degree of difficulty, but THK can not guarantee the accuracy of this effect. Therefore, when ordering, please specify the additional processing required.

Q. What is the maximum allowable speed?
A.
The upper limit speed is: the DN value of grease lubrication is less than 80000 and the oil lubrication is less than 100000.
D: Rolling pitch circle diameter (mm)
N: revolutions per minute (min-1)


Q. What is the difference between rated load C and C0?
A.
The basic load rating C is the value used to calculate the life of the collar. C0 is the maximum allowable load.
