New Type of Rolling Element Linear Motion Bearing Translide™
7 Result of Endurance Test
Deterioration in surface roughness is not observed on ball tracks of a rail after running the
distance of the estimated life. (Refer to Fig. 2)

Precautions for using Translide™
Please follow the precautions below for your safety.
● Ambient temperature: 50˚C maximum (80˚C, instantaneous), Maximum speed: 200 m/min.
● Allowable mounting accuracy: Parallelism of two sets: 100 µm, Height variation of two sets: 500 µm/500 mm.
● Consult with NSK when using a Translide in a single rail configuration.
● Be sure to take safety measures against falling loads if you mount a Translide upside down.
● Never use in an environment where degreasing solvents are present.
● Balls fall out if a ball slide is removed from a rail. Use a provisional rail if you need to dismount a ball slide
from a rail. NSK assembles interchangeable ball slides on provisional rails for shipping. Take great care when
inserting a ball slide in a rail.

The basic dynamic load rating C is a load that furnishes 50 km rating fatigue life; it is a vertical and constant load to the ball slide 4
mounting surface. To convert C to C100 for a 100 km fatigue life, divide C by 1.26.
