Live Shaft
Stainless Steel Idlers
Webex Standard Stainless Steel Idlers are ideal for use in aggressive
environments where corrosive or abrasive elements can damage normal
steel idlers. These Corrosion Resistant (CR) idlers are also specified
frequently for clean room, food grade and medical applications,
or wherever high moisture conditions exist. Like steel rolls, Stainless
Steel Idlers also have the strength to withstand substantial loading
from nips or web tension. They perform well in elevated temperatures.
For greater wear-resistance, Stainless Steel Idlers can be readily
plated with plasma coating, nickel or chrome. To ensure maximum
performance over a wide range of conditions, Webex Stainless Steel
Live Shaft Idlers are constructed with 304 stainless steel. For
more aggressive environments, other stainless steel grades are available.
Application Advantages
Live Shaft Stainless Steel Idlers are often ideal whenever the
web or the environment challenges roll integrity or performance.
Here are a few examples of such challenges:
- Highly
Corrosive Environments
High
moisture environments can rust and corrode steel idlers. Webs
made of PVC materials can form hydrochloric acid. Certain processes
require the use of caustic solutions. All these can damage steel
and impact the performance of standard steel idlers.
- Elevated
Temperature
(Any idler intended for use in elevated temperatures must
have proper venting to avoid explosion. Be sure you identify such
applications upon ordering). Webex Live Shaft Stainless Steel
Idlers can handle substantially elevated temperatures with proper
venting. This makes Live Shafts ideal in ovens where an elevated
temperature or solvent atmosphere would quickly destroy dead shaft
roll bearings.
- Harsh
Environments
By positioning the roller bearings out of the immediate web path,
exposure to process contaminates is minimized. That's why Live
Shaft rolls are often ideal in applications where chemical, dust
or vapors commonly destroy dead shaft roll bearings.
