ASM Turret Handler ms90 parts

The IKO CRWG3-50 is a crucial mechanical component—a crossed roller guide—in the high-precision motion system of the ASM MS90 sorting machine.

As a hardware entity, it's not a "sensor" or "wiring cable" on the sorting machine, but rather a guiding mechanism used to achieve precise linear motion.

Simply put, it's like the "spine" of the ASM MS90 motion system, providing a high-precision, high-rigidity, low-friction linear motion foundation for core components such as the swing arm and test head, allowing them to smoothly and quickly complete actions such as picking up, placing, and testing.

Let's take a closer look at it: Precise Positioning: From Part Model to Equipment Role

The "IKO CRWG3-50" slider in your image precisely points to its role in the ASM MS90 sorting machine.

Brand: IKO, a brand of Nippon Thompson Co., Ltd. of Japan, renowned for its high-precision needle roller bearings and linear motion technology.

Series: CRWG, belonging to IKO's "internal rack & pinion type crossed roller linear guide". One of the most noteworthy core technologies is its built-in rack and pinion mechanism, which perfectly solves the "cage crep" problem commonly found in traditional crossed roller guides.

Specifications: 3 represents a roller diameter of 3mm; 50 represents a guide rail length of 50mm.

Equipment Affiliation: Due to its close collaboration with ASM, this type of high-precision component is typically used in core motion units. It is the precision motion platform component in the MS90 sorting machine that achieves "precise XY positioning," or the Z-axis guide component of the Pick & Place Unit.

Core Technology Analysis: Why is it irreplaceable?

To help you better understand its role, let's break down its three core technical points:

"Crossed Roller" Arrangement: Cylindrical rollers are arranged alternately at 90° angles to each other between the guide rails. This structure allows it to withstand loads from any direction, including radial and axial, ensuring the stability of the sorting machine during high-speed movement.

"Rack & Pinion" Anti-Cage Creep: This is a major highlight of the CRWG series. Traditional crossed roller guides suffer from roller retainer misalignment during high-speed or vertical shaft operation. The CRWG3-50, with its built-in small precision rack and gears, forces the retainer to synchronize with the guide rail, completely resolving this issue.

High rigidity through "line contact": Compared to ball guides ("point contact"), its rollers make "line contact" with the guide rail, resulting in a larger contact area and significantly improved rigidity and load capacity. This allows the MS90 to accommodate multiple test modules for high-speed, high-frequency operation.

Core parameters: The cornerstone of precise data. A typical IKO CRWG3-50 crossed roller guide assembly consists of two guide rails and two sets of roller retainers. Its core parameters are as follows: Parameter Category | Specific Parameter Value | Key Model | Model: CRWG3-50; Weight: Approx. 94.58g; Origin: Japan | Core Performance | Dynamic Rated Load (C): 2740N; Static Rated Load (C0): 3660N; Allowable Load (F): 1220N (both are rated values for a 4-rail + 2-roller combination) | Key Dimensions | Stroke Length: 13mm; Rail Width (A): 18mm; Rail Height (H): 8mm; Rail Length (L): 50mm; Roller Diameter (Dw): 3mm; Number of Rollers (Z): 6 | Installation Information | Mounting Hole Spacing (F): 25mm; Mounting Thread: M4 (for easy fixing) | Regarding the parameters, one point needs special explanation: the rated load in the table is the combined value of "4 rails + 2 rollers". While a basic CRWG3-50 unit includes two guide rails and two sets of roller retainers, the ASM MS90 may use two sets (i.e., four guide rails) in parallel along critical axes to achieve ultra-high rigidity and stability. This is a common design approach for high-precision equipment.

Maintenance and Spare Parts Recommendations

To ensure stable equipment operation, we recommend:

Lubrication and Cleaning: Using a suitable lubricant and keeping the guide rails clean is crucial for extending their lifespan.

Summary

Therefore, the "IKO CRWG3-50" crossed roller guide rails in your image are the core physical foundation enabling the ASM MS90 sorting machine to achieve sub-micron level positioning accuracy and high-speed operation. This small component is a key element in ensuring the equipment can stably produce high-yield chips.
