Frequently Asked Questions
What shaft diameter does the SC8UU fit?
The SC8UU is designed for standard 8 mm diameter hardened smooth rods (linear shafts). Ensure your shaft is ground and hardened for optimal bearing life and smooth motion.
What is the difference between SC8UU and LM8UU?
The LM8UU is the bare cylindrical linear bearing, while the SC8UU includes the same LM8UU bearing pre-installed inside an aluminum housing block with four M4 mounting holes. The SC8UU is ready to bolt onto a flat surface, making installation much easier.
Can I use this on a vertical axis?
Yes, the SC8UU works on vertical, horizontal, or angled axes. For vertical applications, pair it with a lead screw or belt drive to prevent the carriage from sliding under gravity.
How many SC8UU bearings do I need per shaft?
For stable motion without rocking, use at least two SC8UU blocks per shaft, spaced apart on the carriage. Most 3D printers and CNC machines use two bearings per rod.
Does it require lubrication?
It comes pre-lubricated. For extended life, periodically apply a light machine oil or lithium grease to the shaft and bearing, especially in dusty environments or after prolonged use.
