[Clean & Pack]Pulleys for Flat Belts - Width L = 25 to 100 (Part Numbers)

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.

Cleaning Process

· Degreasing (Part Number: SL-□□)

* Stainless steel products may be used with alkaline hot pure water. There is no change in cleanliness.
* If the surface treatment is low-temperature black chrome plating, IPA cleaning will be applied.

Working Environment: General environment
Hydrocarbon cleaning Ro water cleaning Neutral Detergent Cleaning		High-pressure jet washing (Ro water) followed by pure water cleaning		Oil-free Compressor Used		Anti-rust single packing

· Precision cleaning (Part Number: SH-□□)

				Working Environment: Class 1,000				Working Environment: Class 10
Hydrocarbon cleaning Ro water cleaning Neutral Detergent Cleaning		High-pressure jet washing (Ro water) followed by pure water (10 MΩ·cm) cleaning		Use pure water (13 MΩ·cm)		Use nitrogen blow		Conducted on a clean bench in a Class 10 clean environment

· Electrolytic polishing + precision cleaning (Part Number: SHD-□□)

						Working Environment: Class 1,000				Working Environment: Class 10
Hydrocarbon cleaning Ro water cleaning Neutral Detergent Cleaning		Electrolytic polishing with an electrolytic polishing layer according to the material		High-pressure jet washing (Ro water) followed by pure water (10 MΩ·cm) cleaning		Use warm pure water (13 MΩ·cm)		Use nitrogen blow		Conducted on a clean bench in a Class 10 clean environment

Packaging Example

For degreasing:
(Part Number: SL-□□)

Depending on some products and dimensions,
packaging type may vary.

For precision cleaning or electrolytic polishing + precision cleaning:
(Part Number: SH-□□/SHD-□□)

[ ! ] Both the first and second layer packaging are degassed.
