SAMICK Linear Bushing, LM type is the linear motion system with unlimited stroke by applying with LM shaft.
Because of the point contact between Balls and LM shaft, minimum friction can be acquired and that can give yot thr high precision motion. SAMICK Linear Bushing services the alignment of the balls toward the LM Shaft by the single Retainer and cylindrical shape Raceway. Outer Sleeve is made of high-carbon Chromium Bearing Steel and inner and outer grinding processes are applied after Heat treatment.
The Dimensions of SAMICK Linear Bushing are standardized to have full interchangeability. LM shaft is provided with the cylindrical grinding to have high precision fitting dearance.
Hardness and Precisely ground Outer Sleeve is made of Bearing Steel and can be direct assembled with the needle bearing on outer surface.
The single body retainer guides 4~ 6 ball circuits, and it makes the precision guiding against the balls moving direction and smooth motion.
LM Case Unit, SC type is consist of th elight Aluminum case and LM type Linear Bushing, so the assembly can be finished by simple boltong. Longer life can be obtained by adjustng the Ball circuit orientation of Linear Bushing against the direction of load.
SAMICK Linear Bushing are widly used in Precision equipments Computer and peripheral equipments, Measuring equipments, Auto recording equipments and 3D measureing equipments and Linear Motion systems in Machine for Mass Production : Multi-Axis Drilling machines, Punching Press, Tool Grinders, Auto-Gas cuters, printing machines, card selectors food packing machines and etc.
