The dirt and thread guard on our workshop trolley assistant fulfils several important functions in day-to-day work

Protection against wear

Workshops constantly produce

• Metal shavings
• Dust
• Oil and grease residues

Without the protective ring (dirt and thread guard) on the castors, these particles get into the bearings of the castors and cause faster wear and sluggish castors.

The protective ring also prevents hair, threads or dirt from wrapping around the wheel axle and blocking the bearing (the thread guard)

"Threads" means, for example:

• Textile fibres (rags, clothing)
• Cable remnants or plastic threads

These can wrap themselves around moving parts, especially on rollers.

With thread protection:

• No tangling
• Rollers remain smooth-running
• Less maintenance required

Function: They protect the ball bearing from dust and dirt, which increases the service life and keeps the rolling resistance low.

Less dirt and no tangles = significantly longer service life of the components = more fun with your workshop trolley!

This is particularly important for high-quality trolleys (e.g. for industrial use).

Reliability in daily use

A workshop trolley is constantly being moved and opened.
If castors block:

• costs time
• annoying in the workflow
• can be dangerous in the worst case

In short:

Dirt and thread protection ensures that a workshop trolley remains permanently smooth-running, reliable and low-maintenance - even under harsh workshop conditions.
