Cylindrical Ball Spline "LBS": THK

Cylindrical Ball Spline "LBS": THK

It is a cylindrical straight spline nut. It is the most compact type that transmits torque by driving in a key.

【 Angular Latch "Zero"】 The high-torque ball spline can reduce angular latch to zero and increase rigidity. It facilitates a more compact design compared to conventional ball splines. 【 High Rigidity and Accurate Positioning】 With a large contact angle, minimal initial displacement, high rigidity, and precise positioning accuracy can be achieved. 【 Capable of High-Speed Motion and Rotation】 Thanks to low friction, an excellent lubricant retention structure, and a rigid retainer, long-term use with grease lubrication is possible even for high-speed linear motion. Additionally, the influence of centrifugal force acting on the balls during high-speed rotation is minimal, allowing for smooth linear motion. 【 Compact Design】 The outer diameter of the spline nut is small, enabling a compact design that does not take up much space. 【 Ball Retention Type】 The retainer prevents the balls from falling out even when the spline nut is removed from the spline shaft. 【 Usable as Heavy Load Linear Bush】 The ball rolling surface has a large contact area and exhibits high load performance against radial load. 【 Change from Parallel Use of Two Axes to Single Axis Use】 Areas previously using two axes in parallel can be converted to a single axis.

Gear-equipped rotary ball spline "LBG": THK

Gear-equipped rotary ball spline "LBG": THK

This is a unit with gear machining on the flange outer circumference and a bearing assembled in the nut section. It is ideal for a torque transmission mechanism driven by a spline nut.

The rotary ball spline is a unit type where gear machining is done on the outer peripheral part of the LBR-shaped flange, and radial and thrust bearings are compactly combined in the spline nut section. The ball rows are held in a way that allows them to move in a circular motion, aligned by a special synthetic resin retainer, ensuring that the balls do not fall out even when the spline shaft is removed. 【Angular Backlash "Zero"】 Due to the structure where three rows of rolling protrusions are evenly distributed around the outer circumference of the spline shaft, the ball rows are pinched, allowing for preloading to be applied, which eliminates backlash in the rotational direction and increases rigidity. 【Compact Design】 The structure combines radial and thrust bearings compactly in the spline nut section, allowing for a compact design. 【High Rigidity】 By applying a suitable preload with a large contact angle, high torque rigidity and moment rigidity can be achieved. Additionally, the needle bearings in the support section allow for strong support of the nut against radial loads, enhancing rigidity. 【Optimal for Torque Transmission of Spline Nut Drive】 The support bearings enable rigid support of the nut, making it optimal for torque transmission in spline nut drives.

Combined motion of rotation and linear movement Ball screw and spline 'BNS': THK

Combined motion of rotation and linear movement Ball screw and spline 'BNS': THK

This is a ball screw that achieves a combination of rotational motion and linear motion, known as "helix," by incorporating a ball screw groove and a ball spline groove on a single shaft.

Linear motion + rotational motion. The BNS type is a stroke and rotation unit that features a ball screw groove and a ball spline groove crossed on a single axis, with dedicated support bearings directly incorporated into the outer circumference of both the ball screw nut and the spline outer cylinder. By rotating or stopping the ball screw nut and the spline outer cylinder, it is possible to achieve rotational motion, linear motion, and spiral motion on a single axis.

Compact Ball Spline LT-X / LF-X / LTR-V: THK

Compact Ball Spline LT-X / LF-X / LTR-V: THK

This is a ball spline with a nut shape that has become more compact compared to the conventional LT/LF type due to the new circulation path.

The new circulation path enables a compact nut shape. Compared to the conventional LT/LF types, the outer diameter ratio has been reduced by up to 10%, and the variation in sliding resistance has decreased, allowing for smooth operation. It achieves optimal ball circulation and enables high-speed operation. Additionally, there is the compact rotary ball spline LTR-V, which directly incorporates a support bearing into the outer circumference of the LT-X spline nut. For more details, please refer to the catalog or feel free to contact us.

Press-type ball screw integrated ball spline 'DSP': THK

Press-type ball screw integrated ball spline 'DSP': THK

The DSP, born for press use, integrates linear guidance and drive. It transmits great thrust with smooth movement.

The integrated structure of the ball spline for linear motion guidance and the ball screw as the drive source transmits large thrust with smooth movement. Since the drive and linear motion guidance are integrated, a more space-saving structure is possible compared to conventional designs. By reducing the number of components, it contributes to the efficiency of equipment manufacturing through reduced assembly labor and shortened processing time for parts.

Ball spline

Ball spline

Large load capacity, zero clearance in rotation direction, high performance, high rigidity, and easy assembly.

Features of Ball Splines High Load Capacity Ball splines utilize a precisely ground rolling surface with a 40° Gothic arch contact angle, resulting in a significant load capacity for both radial loads and rated torque due to the increased contact angle. Zero Play in Rotational Direction The spline shaft and spline outer cylinder are composed of a 40° contact angle with two-row and four-row ball arrays. By properly adjusting the pre-load, the play in the rotational direction can be reduced to zero, enhancing rigidity. High Performance The ball in the raceway is composed of unique contact points, providing high rigidity, high performance, and low friction for energy savings. High Rigidity The raceway has a large contact angle (40°), which results in high rigidity. Additionally, by applying appropriate pre-load, excellent torque rigidity and moment rigidity can be achieved. Ease of Assembly Due to special design, the balls do not fall out even when the spline outer cylinder is removed from the spline shaft. Therefore, assembly, maintenance, and inspection become easier.
