Mounted Linear Ball Bearings
Bearings are for use with round end-supported shafts. All have end seals to keep lubricant in and dirt out.
Fixed-alignment bearings are for use where shaft misalignment is unlikely.

Metric Precision Ball Screws and Nuts
Precision cut threads make these metric ball screws approximately four times more accurate than standard ball screws. Use them when exact positioning is essential. They come with finished ends and the nut already on, so they’re ready to use right away. The ball nuts have a flange design that makes it easy to mount objects on them. Inside, they have ball bearings to produce smooth, low-friction travel for applications that require high-speed and repeatable movement.
Ball nuts with a travel distance per trun greater than 1 mm have a seal that prevents some contaminants from getting inside them. However, to make sure they don’t create torque and heat, there’s a bit of clearance between the seal and screw, so the seal can’t keep out everything.
Root diameter indicates the diameter the ball screw will be after machining away the threads.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
