The KK linear module adopts a fully enclosed ball screw structure, with a linear repeat positioning accuracy of up to ±0.01mm and a running speed exceeding 2m/s. As a core transmission component in the field of industrial automation, the KK module has become an indispensable key component in intelligent manufacturing equipment due to its high precision, high rigidity and stable performance. The following is an introduction to the Dinghan KK precision linear module.

I What are the advantages of the Dinghan KK type precision linear module?

Its core advantages are reflected in three aspects: Firstly, it adopts a double-row angular contact bearing preload design, effectively eliminating reverse clearance; secondly, the aluminum alloy body undergoes T6 heat treatment, enhancing rigidity while reducing weight; thirdly, it is equipped with a standard dust-proof sealing system, with an IP54 protection level ensuring long-term stable operation in a dust-free workshop.

II. Key Points for Selecting the Dinghan KK Series Precision Linear Module

1. Calculation of Load Characteristics

The axial load (F), radial load (M), and overturning moment (T) need to be comprehensively calculated to ensure that the forces in all directions do not exceed the rated values indicated on the sample. For example, the dynamic allowable torque of the KK60 module is 42 N·m, and the static torque can reach 65 N·m.

2. Principle of Precision Matching

For precision requirements below ±0.02mm, it is recommended to choose preloaded guides in combination with ground lead screws; in ordinary assembly scenarios, rolled lead screws can be selected to reduce costs.

3. Environmental Adaptability

The food and pharmaceutical industries should choose the stainless steel version; in high-temperature environments (＞80℃), special lubricating grease and heat-resistant sealing parts are required.

4. Maintenance Cycle Design

It is recommended that the standard model be replenished with grease every 500 kilometers of operation, while the maintenance-free type (such as those with self-lubricating modules) can be extended to 2,000 kilometers.

The above is an introduction to the KK type precision linear module. The precision linear module adopts a modular design and is mainly composed of core components such as linear guides, ball screws, drive motors, aluminum alloy profile bases, and sliders. From the feedback of actual application, after parts manufacturers adopted the KK module in batches on the stamping line, the mold changing time was shortened.
