How Often Should Cleaning Agents Be Used for Linear Modules?
The frequency of using cleaning agents for linear modules mainly depends on the module’s working environment and contamination level. Below are some recommendations:
Daily Cleaning
For daily dust and dirt, simple cleaning can be performed with a dry cloth or vacuum cleaner. This can be done daily or regularly, based on the cleanliness of the working environment and actual usage conditions.
Regular Deep Cleaning
For heavy dirt or grease, deep cleaning with a cleaning agent may be required. The frequency of deep cleaning is determined by the module’s operating environment and contamination level. Generally, deep cleaning once a month or once every quarter is appropriate.
On-Demand Cleaning
If the linear module is severely contaminated, or if special stains and grease need to be removed, cleaning can be carried out as needed. In such cases, consult the manufacturer or professional maintenance personnel for proper cleaning methods and frequency.
Note
When using cleaning agents on linear modules, follow the manufacturer’s recommendations and operating manual to ensure proper cleaning agents and methods are applied, so as to avoid unnecessary damage or performance degradation. Meanwhile, the cleaning frequency and methods can be flexibly adjusted according to actual usage and working conditions to maintain the module’s good condition and performance.

With the popularization of industrial automation, more and more enterprises adopt multi-axis manipulators to replace manual labor. What are the characteristics of these modules? Today we will explain the unique internal structure of PMI linear modules.
Integrating PMI’s technology and experience in linear guides and ball screws, PMI linear modules feature an integrated design of the nut and slider, paired with an optimized high-rigidity U-rail profile. This achieves optimal space utilization and greatly reduces installation time, ensuring high rigidity and high precision.
The ball rolling surface adopts a 2-row Gothic arch design with a 45° contact angle, providing four-directional load capacity.
The ball rolling surface of the U-rail is designed with 2 rows of Gothic arches and a 45° contact angle, delivering four-directional load capacity and suitability for any mounting orientation.
The integrated slider-nut design, which combines the linear guide slider and ball screw nut, enables the KM series to achieve optimal space utilization.
The U-rail profile is optimized via FEM (Finite Element Method), achieving an ideal balance between lightweight design and high rigidity.
The 2-row Gothic arch design and stable manufacturing process minimize deformation caused by fluctuating loads, ensuring smooth and stable operation to meet high-precision feeding requirements.
Through the above overview of the PMI linear module structure, we believe most customers have gained a clear understanding. For any questions during practical application, please feel free to contact us.

A Brief Discussion on Common Structural Types of Linear Modules
With the popularization of industrial automation technology, more and more enterprises are adopting intelligent machinery. From unmanned supermarkets to unmanned convenience stores, automation is being gradually implemented, and machines may one day replace manual labor. In the long run, this is an inevitable future trend. To avoid being eliminated, continuous progress is essential.
Dongguan Jiayi is no exception. Since the first half of this year, we have entered the R&D phase of new products, focusing on linear modules, screw modules and other manipulator components. Below we explain several common structures used in mass production.
