Stop Overpaying for New Parts. Get Precision Japanese Engineering for Less.
You run a factory. You know the pain of a machine going down. You also know that buying brand-new replacement parts from Japan costs a fortune and takes weeks to ship. You need a solution that is fast, cheap, and works perfectly.
We have exactly what you need. This is a disassembled KAIJO cross slide plate assembly. It comes with a high-precision 1205 ball screw. The travel distance is 59mm by 84mm. This is a real Japanese import. It is not a cheap copy. It is built for heavy-duty industrial use.
We strip these units from working machines. We test them. We clean them. Then we sell them to you at a fraction of the cost of new ones. You get Japanese quality without the Japanese price tag. Stop waiting for shipping. Start fixing your machines today.
What Exactly Is This KAIJO Cross Slide Assembly?
Let’s break this down simply. This is not just a random piece of metal. It is a complete motion control system. “Cross slide” means it moves in two directions (X and Y). It allows you to position things with extreme accuracy.
The star of the show here is the 1205 ball screw. This is the industry standard for precision linear motion. The “12” means the screw shaft is 12mm wide. The “05” means the lead (how far it moves in one turn) is 5mm. This gives you a great balance of speed and force.
KAIJO is a famous Japanese brand. They make equipment for semiconductors and electronics. When you buy a KAIJO part, you are buying reliability. These parts were designed to run 24/7 in clean rooms. They are made of high-grade aluminum and steel. They do not bend. They do not warp.
This specific unit has a travel range of 59mm x 84mm. This is a common size for small to medium positioning tables. It is perfect for aligning lenses, sensors, or small mechanical parts.
Technical Specs: The Numbers That Matter
You need to know if this fits your machine. Here are the hard numbers. We list them clearly so you don’t have to guess.

Why Choose a “Disassembled” Part?
You might be worried about used parts. Let us tell you why this is a smart business move.
First, Cost. A new KAIJO stage costs $1,000+ easily. This refurbished unit costs a fraction of that. You save 60% to 80%.
Second, Availability. New parts from Japan have a 4-week lead time. Your machine is broken now. We have these in stock. We ship immediately.
Third, Quality Control. These parts come from Japan. Japanese factories maintain their machines perfectly. This part was likely removed because the machine was upgraded, not because it broke. It has plenty of life left. The ball screw probably has less than 500km of travel on it. That is basically new for a factory machine.
We clean the old grease. We check for play in the bearings. We make sure the screw turns smoothly. If it’s not good enough for us, we don’t sell it.
Where Can You Use This? (Real World Scenarios)
This 59x84mm slide is versatile. Here are three common ways our customers use it.
Scenario 1: Semiconductor and PCB Testing
KAIJO makes wire bonders and inspection machines. If you are repairing a PCB tester, you need precise X-Y movement to align the probe needles. This slide provides the exact rigidity needed to hold the probe steady. It stops the “wobble” that ruins test results.
Scenario 2: Laser Marking and Engraving
In laser marking, focus is everything. You need to move the laser head or the part very slightly. A 1205 ball screw gives you smooth, jitter-free movement. You get clean, sharp marks on metal or plastic. The 59x84mm size is perfect for small jewelry or electronic components.
Scenario 3: DIY CNC and 3D Printers
Hobbyists and small shops love these. If you are building a desktop CNC mill, you need a solid base. This aluminum plate is stiffer than 3D printed plastic. It handles the cutting forces better. The 1205 screw gives you the resolution to cut fine details in wood or aluminum.
Scenario 4: Medical Device Assembly
Medical devices need high reliability. You are assembling syringes or diagnostic kits. You need a stage that won’t drift over time. This unit holds its position well. It is clean (we wipe it down) and suitable for light clean-room use.
Installation and Maintenance Tips
Installing this is not rocket science, but you need to be careful.
- Mounting Surface: Make sure you bolt this to a flat surface. If the surface is warped, the slide will bind and the motor will skip steps. Use a machinist’s square to check the angle.
- Alignment: When connecting the motor to the ball screw, use a flexible coupler. Do not rigidly connect them. Even a tiny misalignment will destroy the bearings in a month.
- Lubrication: We ship it greased. Do not over-grease it. Too much grease attracts dust. Add a drop of light oil every 6 months if it runs dry.
- Dust: If you use this in a dusty workshop, add a simple rubber strip or a bellows cover. Dirt is the #1 killer of ball screws.
Frequently Asked Questions (FAQ)
Q: Is the ball screw ground or rolled?
A: It is a rolled screw (C3 or C5 precision). Ground screws (C7 or better) cost 10x more. For 95% of factory automation, rolled screws are perfect. They are durable and handle heavy loads better.
Q: Does it come with a motor?
A: No. This is the mechanical assembly only (plate, screw, nut, bearings). You reuse your existing stepper or servo motor. This saves you money if you already have a spare motor.
Q: What is the max load it can hold?
A: With a 12mm screw, it can handle about 50kg of static load. For dynamic movement (moving while cutting), keep it under 10kg for best accuracy.
Q: Do you ship to my country?
A: Yes. We use DHL or FedEx. It usually takes 3-5 days to reach the US, UK, or Europe.
