More about: THK PA15

Note 1: Guidance for Installing the Spring Pad:The below figure shows examples of installing the spring pad model PA to the bottom of the LM Roller and adjustingthe clearance and providing a preload.The dimensions in this example are indicated in the specifi cation table for the spring pad model PA.The following is the procedure for the installation.
(1) Secure the fi xture and the spacer. Adjust them so that the LM Roller can move vertically.
(2) Turn the adjustment bolt until the LM Roller hits the raceway.
(3) Turn the adjustment bolt using a torque wrench and tighten it until the desired torque is reached.A preload is provided via the spring pad model PA.

Application of THK THK PA15

1. THK PA15 THK’s linear motion system helps to provide a guide device that enables this precision and speed to be realized.
2. THK PA15 In order to repeat the production of this advanced product, the LM guide and ball screw in the milling machine guide system which don’t waste of action
3. The LM guide and ball screw are indispensable for the movement of the tool section of the lathe because of its high rigidity and high precision.
4. By combining LM guides and ball screws with lubrication parts, we can reduce system design work and assembly steps, and extend the interval needed for maintenance.
5. Frequent earthquakes have caused great concern among residents in some regions. The vibration control system of THK THK PA15 can help solve the problem.
The system is based on the application technology of LM guide ball screw. It can provide protection to people’s life and life in earthquake. The system can not only prevent the damage caused by the earthquake, but also reduce people’s panic because of its omnipresent, reliable and durable.
