Product Overview
E-KUA/E-KUAC single axis unit, which has standardized the mechanism self-made by the customer with high usage frequency, is driven by rolled/precision ball screw to achieve high precision positioning. High-load transfer is also made possible by using a linear guide for medium and heavy load.
Product Features
Feature 1: High precision. Achieves high precision positioning through the combination of linear guide and ball screw.
Feature 2: Low cost. Saves time in design, procurement and assembly, significantly reducing labor costs for customers.
Feature 3: Heavy load resistance. Suitable for high and heavy load transfer thanks to the use of a linear guide for medium and heavy load.
Structure Features
Adopts a lightweight aluminum base with high rigidity, featuring a ball linear guide.
Driven by rolled screw, two products (without cover type and with cover type) are added to the lineup.

Usage Method
■ Mounting Method
Mount by positioning on the side of the base.
To ensure the precision of the single axis unit, fix it to an iron plate with flatness of ±0.02mm or less and thickness of 20mm or more through the mounting holes of the base, otherwise the base will be deformed and jamming will occur.
See above for motor mounting method.


■ Maintenance Method
①Grease Replenishment Method
Ball screw: After applying grease directly to the ball screw, move the sliding table by hand over the full stroke to achieve overall uniform application.
     Linear guide: Insert the grease gun into the slider oil nozzle and inject grease.
     After injection, move the table over the full stroke several times to achieve overall uniform application.
     Recommended grease: Showa Shell Albania Grease S2.

②Frequency of Grease Replenishment
     Replenish grease every 6 months (or when the travel distance reaches 1000KM).
     The replenishment interval varies with operating conditions and operating environment. Please make appropriate judgments.
Precautions
■ Product Arrival and Usage:
     ①The sensor unit and the single axis unit are shipped in the same package. The customer installs by himself.
     ②Due to the large number of fine parts, please check the supplied parts immediately after unpacking.
     ③Turn on the power and use the product after ensuring safety in the surroundings, thus avoiding equipment damage or personal injury accidents.

■Operating Environment
     Use at an ambient temperature of 50°C or less. Recommended operating temperature: 0 to 50℃ (without freezing or condensation).

■Avoid using the single axis unit in the following environments
     ①Dusty environment (especially metal powder)
     ②Environment with splashing water and oil
     ③Near fire sources
     ④Environment with excessive organic solutions and salt
⑤Environment with direct sunlight and heat radiation
⑥Environment subject to strong vibration and shock
⑦Environment with corrosive gas, combustible gas

Frequently asked question (FAQ)

Question: Do single axis units come with couplings?
Answer: Single axis units do not come with couplings. MISUMI has recommended coupling models. Please select the appropriate coupling model referring to the "Examples of Applicable Coupling - Models" in the Specification Table for Single Axis Unit Selection.
Question: Is the optional sensor already installed on the body of the single axis unit when the product is shipped?
Answer: When the single axis unit is shipped, the sensor is not installed on the body. The sensor unit is packaged separately and shipped as an accessory in the original packaging carton for the body of the single axis unit. Upon arrival of the product, the customer needs to install the sensor himself.
Question: Do you sell single axis units in a set along with a motor?
Answer: Single axis units are not sold in a set along with a motor. The customer needs to select and purchase the motor himself. You can choose the appropriate motor model referring to the "Motor Application Table" in the MISUMI catalog.
Question: How to install the sensor?
Answer: The installation method of the sensor varies with the specific operating conditions of the customer. The commonly used method is to install an origin sensor in the middle of a single axis unit and a limit sensor at both ends.
