All products used in the cleanroom have a common requirement: As less particles as possible should be emitted into the environment during operation. This is especially applicable for moving machine parts. To generate as less particles as possible, high abrasion resistance is called for - and is thereby also an indicator for long service life. This is a design and development objective of all igus® products. This brochure lists all certified products including plastic bearings, e-chains and cables that are suitable for use in cleanroom environments.
