THK Ball Spline
THK ball splineThe Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft,Website:, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.THK ball spline contain THK Caged Ball Spline SLS/SLF、THK High Torque Model LBS、THK Medium Torque Model LT、THKRotary with Gears Model LBG、THK Rotary Model LTRTHK Caged Ball Spline SLS/SLFThe adoption of the ball cage enables the circulating motion of evenly spaced balls to be maintained and highspeed response to be achieved. In addition, it eliminates collision and mutual friction between balls, and realizes low noise, pleasant running sound and low particle generation.As the grease retention is increased, long-term maintenance-free operation is also realized.1.THK ball spline-Model SLS (medium-load type)The circumference of the spline nut is shaped in a straight cylinder. Using a key, this model can be secured to the housing, or transmit a torque.2.THK ball spline-Model SLS-L (heavy-load type)A heavy-load type with the same outer diameter as model SLS and a longer spline nut. It is optimal in cases where a large torque is applied in a small space, and in cases where an overhang load or moment is applied.3.THK ball spline-Model SLF (medium-load type)This type is equipped with a flange that enables the product to be secured to the housing using bolts. It can easily be assembled, and allows a shorter housing than securing it using a key.THK High Torque Model LBSThis 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.With the high torque type Ball Spline, the spline shaft has three crests positioned equidistantly at 120 degree, and along both sides of each crest, two rows of balls (six rows in total) are arranged so as to hold the crest.1.THK ball spline-LBSThe most compact type with a straight cylindrical spline nut. When transmitting a torque, a key is driven into the body. The outer surface of the spline nut is provided with anti-carbonation treatment.2.THK ball spline-LBSTA heavy load type that has the same spline nut diameter as model LBS, but has a longer spline nut length.It is optimal for locations where the space is small, a large torque is applied, and an overhang load or moment load is applied.3.THK ball spline-LBFThe spline nut can be attached to the housing via the flange, making assembly simple. It is optimal for locations where the housing may be deformed if a keyway is machined on its surface, and where the housing width is small.Since it allows a dowel pin to be driven into the flange, angular backlash occurring in the fitting can completely be eliminated.4.THK ball spline-LBRBased on the heavy load type model LBST, this model has a flange in the central area, making itself optimal for locations under a moment load such as arms of industrial robots.5.THK ball spline-LBHIts rigid rectangular spline nut does not require a housing and can be directly mounted on the machine body. Thus, a compact, highly rigid linear guide system is achieved.THK Medium Torque Model LTThis Ball Spline has a large load capacity in the radial and torque directions since the spline shaft has 2 to 3 crests on the circumference, each held by 2 rows (4 or 6 rows in total) of balls under a load in order to reasonably provide a preload.With the medium torque type Ball Spline, the spline shaft has two to three crests on the circumference, and along both sides of each crest, two rows of balls (four or six rows in total) are arranged to hold the crest so that a reasonable preload is applied.1.THK ball spline-LTThe most compact type with a straight cylindrical spline nut. When transmitting a torque, a key is driven into the body.2.THK ball spline-LFThe spline nut can be attached to the housing via the flange, making assembly simple.It is optimal for locations where the housing may be deformed if a keyway is machined on its surface, and where the housing width is small.Since it allows a dowel pin to be driven into the flange, angular backlash occurring in the fitting can completely be eliminated.3.THK ball spline-LT-XThis model is much more compact than the standard LT. The length and external diameter of the LT-X ball spline’s outer cylinder are the same as those of an LM-series linear bush, enabling the user to replace a linear bush with the LT-X.4.THK ball spline-LF-XThe nut is more compact than that of the current Model LF thanks to the new circulating pathways. The outer diameter of the nut is the same as that of the linear bushing. The Model LF-XL is suitable for moment loads, torque, and overhung loads that exceed those tolerated by the Model LF-X.THK Rotary with Gears Model LBGThis model is a unit type that has gear teeth on the flange circumference, and radial and thrust needle bearings compactly integrated on the spline nut. This Ball Spline is optimal for a torque transmission mechanism with spline nut drive.1.THK ball spline-LBGThese models are unit types based on model LBR, but have gear teeth on the flange circumference and radial and thrust bearings on the spline nut, all compactly integrated. It is optimal for a torque transmission mechanism with spline nut drive.2.THK ball spline-LBGTThese models are unit types based on model LBR, but have gear teeth on the flange circumference and radial and thrust bearings on the spline nut, all compactly integrated.It is optimal for a torque transmission mechanism with spline nut drive.THK Rotary Model LTRThis model is a compact unit type of Ball Spline whose support bearings are directly integrated with the outer surface of the spline nut.1.THK ball spline-LTRA compact unit type whose support bearings are directly integrated with the outer surface of the spline nut.2.THK ball spline-LTR-AA compact type even smaller than LTR.For detailed product information, please refer to the attached PDF file.
