THK Ball Spline 2LBST40UUCLFM+400LF (High Torque Model LBS)
The 2LBST40UUCLFM+400LF bearing is a THK Linear Motion with an an outer diameter of 60 mm, a width of 60 mm. It typically uses Normal grade grade precision tolerances and UU type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
The Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.
High Torque Model LBS
This Ball Spline has no angular backlash to increase the rigidity by providing a preload with one spline nut since the spline shaft has 3 crests equidistantly arranged at 120 degrees on the circumference, each held by 2 rows (6 rows in total) of balls under a load .
