For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.
Shielded bearings dissipate heat more efficiently than sealed bearings.
Sealed bearings block out dust and other contaminants better than shielded bearings.

Air Slides
Convenient for use with devices such as grippers and printing heads, these air slides have a nonrotating head that provides steady motion and a larger mounting area than air cylinders. Air slides have two guide rods parallel to the piston that keep the head from twisting as it extends and retracts.
The magnetic piston inside these slides can activate relays and controllers when used with a sensor (not included). When the piston moves past the sensor, the sensor activates. You can use multiple sensors—attach one for each action to trigger.
