About this item

• •Description:
• •-LMKLUU series Linear Ball Bearing Slide Block Units are complementary to linear ball bearings.
• •-They usually consist of a light-weight, aluminum housing to provide high strength and stiffness.
• •-Compact design with High load carrying capacity, Linear Motion Bearing Unit is a rolling friction supporting element that usually used for linear motion mechanical parts with small friction.
• •-Coordinate with Linear Motion Shaft, recirculating balls provide unlimited stroke at low friction movement, permit temperature within 80 degree Celsius.
• •-It is great for 3D printer, CNC, and other applications.
