Product Introduction
The KOGANEI CS4HA is a compact pneumatic slide cylinder designed for precision linear motion in tight spaces. It is commonly used in pick-and-place units and small assembly machines where reliability is non-negotiable.This unit integrates a slide guide directly into the cylinder body, which saves mounting time and ensures stability. It operates effectively within a pressure range of 0.1 to 0.7 MPa. Unlike larger actuators, the CS4HA focuses on high repeatability for light loads, making it a staple in electronics manufacturing.

Application Scenarios & Pain Points
Imagine a PCB handler jamming because a component wasn’t pushed fully into the tray. The culprit is often a worn-out or underpowered slide cylinder that lacks the rigidity to handle the side load. The KOGANEI CS4HA solves this by integrating the guide rails directly with the pneumatic drive, ensuring the rod doesn’t rotate or deflect under light lateral forces.
- Electronics Assembly: If you are handling small chips or connectors, this cylinder provides the necessary precision without crushing delicate parts.
- Pick-and-Place: It excels in moving light objects between conveyors. The compact footprint allows for high-density mounting on small carriages.
- Testing Jigs: Used to actuate switches or buttons. The consistent stroke length (10mm) ensures uniform pressure application every cycle.
- Medical Dispensing: Often found in fluid dispensing robots where smooth, non-lubricated operation is critical to prevent contamination.
Quality Control Process
We don’t just look at the box; we verify the part. Here is how we inspect the CS4HA before it leaves our warehouse:
- Inbound Inspection: We verify the hologram on the KOGANEI packaging and check the serial number against the packing list. We look for any yellowing of the body or scratches on the guide rails.
- Live Functional Test: We mount the unit on a test rig connected to a 24V DC supply and air source. We cycle it 50 times to ensure the magnetic switch engages correctly and the slide moves smoothly without sticking.
- Leak Test: We submerge the pressurized unit in water to check for bubbles at the rod seal and port connections. Even a tiny leak is a fail.
- Dimensional Check: We use digital calipers to verify the bore and stroke length match the datasheet specs exactly.
- Final QC: The unit is cleaned, placed in an anti-static bag, and sealed with a “QC Passed” label dated for that day.
Installation Pitfalls Guide
I’ve seen too many of these ruined by simple mistakes. Keep these in mind and you’ll cut 90% of your rework time.
- ❗ Side Load Limits: Just because it has a guide doesn’t mean you can hang a heavy toolbox on it. Exceeding the allowable moment load will wear out the slide bushings in days. Check the moment rating chart.
- ❗ Air Line Debris: Blowing out your air lines before connecting the cylinder is mandatory. A single speck of Teflon tape or metal shaving can score the internal seal, causing an instant leak.
- ❗ Mounting Surface Flatness: If your mounting surface isn’t flat, you are pre-loading the slide mechanism. This creates drag and reduces the cylinder’s lifespan. Use a feeler gauge to check the gap.
- ❗ Speed Controllers: Don’t run this at full speed without flow control. The rubber bumpers at the ends are for light cushioning, not stopping a piston slamming at maximum velocity. Meter-out speed control is your friend here.
- ❗ Auto Switch Installation: When installing the magnetic switch, don’t force it into the groove. Slide it in gently from the end of the stroke and tighten the screw just enough so it doesn’t move—over-tightening strips the threads in the plastic housing.
