THK BL10BD is a BL-series Link Ball designed for mechanical linkage applications requiring angular movement. The model features an M10×1.5 threaded connection, a 15.875 mm ball diameter and a permissible tilt angle of 40°.

Application of THK THK BL10BD

THK BL10BD is a compact Link Ball designed for mechanical linkage applications where radial load and angular movement are required. As part of the THK BL series, BL10BD provides a compact and wear-resistant spherical joint for connecting moving components while allowing smooth angular movement. With an M10 × 1.5 threaded connection and a 15.875 mm ball diameter, BL10BD is suitable for a variety of mechanical control, linkage and articulated applications.

1. Mechanical Linkage Systems

THK BL10BD can be used in mechanical linkage systems where motion needs to be transmitted between connected components while allowing angular movement at the joint. The spherical construction allows the connected components to move relative to each other while maintaining a stable mechanical connection.

2. Machine Tools and Industrial Equipment

BL10BD can be used in mechanical control and linkage mechanisms associated with machine tools and industrial equipment. It is suitable for applications where a compact threaded joint is required to accommodate angular movement between connected components.

3. Automation and Control Mechanisms

BL10BD is suitable for automation equipment and mechanical control mechanisms that use linkages to transfer movement between components. The spherical joint can accommodate relative angular movement while maintaining the required mechanical connection.

4. Automotive and Transportation Applications

THK identifies the BL series as suitable for applications such as automobile height sensors and transmission control mechanisms. The compact Link Ball structure is particularly suitable for mechanical control linkages where reliable movement and limited installation space are important.

The BL series is also used for transmission control joints in automobiles, trucks and buses, as well as steering mechanisms for agricultural tractors.

5. Compact Articulated Mechanisms

BL10BD can be used in compact articulated mechanisms where two moving components need to be connected through a threaded spherical joint. Its 40° permissible tilt angle allows the connected components to accommodate angular movement during operation.

6. Radial-Load Applications

Model BL is designed for radial load applications. When selecting BL10BD, the actual load direction, applied load, required angular movement, mounting dimensions and operating environment should be checked carefully.

For applications where the primary load is in the axial direction, other THK Link Ball models such as the RBI series should be considered according to the required load direction and installation conditions.

7. BL10BD and BL10D Thread Difference

BL10BD and BL10D have the same 15.875 mm ball diameter, 40° permissible tilt angle, 18,300 N applied static load and 11,300 N yield point strength. The main dimensional difference is the threaded connection.

Model Thread Ball Diameter Permissible Tilt Angle Mass
THK BL10D   M10 × 1.25     15.875 mm   40°   87 g
THK BL10BD M10 × 1.5     15.875 mm     40°   90 g

The thread specification should be confirmed carefully when replacing or selecting between BL10D and BL10BD.
