Product Introduction

FUJI H65860 – NXT H24/H24G/H24S R-Axis Bearing

Overview

The FUJI H65860 is a high-precision R-axis bearing specifically designed for the rotation axis (R-axis) of the FUJI NXT H24, H24G, and H24S placement heads. This bearing plays a critical role in ensuring smooth and accurate rotation of the nozzle shaft, enabling precise angular alignment during high-speed SMT pick-and-place operations.

It supports the rotational movement of the nozzle unit, allowing for fine-tuned positioning of components with rotational orientation requirements (θ-axis placement).

Key Features

High-Precision Design
Engineered to minimize friction and backlash during rotation, enhancing placement accuracy.

Optimized for R-Axis Movement
Supports continuous and rapid rotary motion required by the nozzle's θ-axis during component alignment.

Sealed and Lubricated
Pre-lubricated with high-grade grease and sealed for protection against dust, flux, and moisture.

Direct Compatibility
Designed specifically for FUJI NXT H24, H24G, and H24S heads — no modification required.

Technical Specifications

Applications

Used in FUJI NXT high-speed placement heads for rotational alignment.
Supports precise angular positioning of nozzles for non-symmetric components.
Critical for achieving high-speed, high-accuracy SMT assembly performance.

Maintenance Tips

Although sealed, monitor for unusual noise or resistance during head rotation.
Replace if signs of wear, vibration, or R-axis error occur.
Avoid contamination during head disassembly — always follow cleanroom protocols.

FAQ Guide – FUJI H65860 NXT H24/H24G/H24S R-Axis Bearing

1. What is FUJI H65860?

Answer:
The H65860 is a high-precision R-axis bearing used in the FUJI NXT H24, H24G, and H24S placement heads. It supports the rotational (θ-axis) movement of the nozzle holder, ensuring smooth and accurate angular positioning of components during pick-and-place operations.

2. What is the R-axis (θ-axis) in FUJI heads?

Answer:
The R-axis, also known as the θ-axis, refers to the rotation of the nozzle to correctly align components based on their angular orientation. The bearing ensures this rotation is stable, low-friction, and accurate, even during high-speed operations.

3. What are the symptoms of a failing R-axis bearing?

Answer:

Nozzle rotation becomes rough, slow, or jerky
Abnormal noise (grinding or squealing) during rotation
Reduced placement accuracy, especially for angular alignment
Vibration or runout in the nozzle tip
θ-axis feedback error or rotation misalignment

4. When should the H65860 be replaced?

Answer:

When showing any of the above symptoms
After extended machine uptime (as part of preventive maintenance)
If contamination (dust, flux, oil) is suspected
After disassembling the R-axis for motor or encoder repair

5. Can it be replaced individually?

Answer:
Yes. The R-axis bearing (H65860) can be individually replaced. However, it requires:

Proper disassembly of the R-axis block
Use of a precision press-fit tool or jig
Avoiding misalignment or stress during reinstallation
Recalibration of θ-axis (if encoder or motor is disturbed)

6. What tools or accessories are needed for replacement?

7. What parts work with the H65860 bearing?

8. How to maintain the H65860 bearing?

Answer:

Do not lubricate if sealed — sealed bearings are maintenance-free
For serviceable types, use manufacturer-approved grease
Clean surrounding area to prevent foreign object contamination
Avoid applying excessive force to bearing during nozzle cleaning
Replace if rotation feels uneven or θ errors increase

9. How often should the bearing be inspected?

Answer:

Every 6 to 12 months, depending on production volume and environment
After any incident involving nozzle collision or vibration
During regular placement head overhauls or preventive maintenance cycles

10. Where can I purchase H65860?

Answer:

FUJI official service centers or authorized SMT parts distributors
