Taber Abradants

Article No. 10063

Crocking Cloths pkg/1000

  • Commonly employed to conduct rubbing / abrasion tests. 
  • Originally used to determine the color fastness of textiles to dry/wet rubbing. 
  • Square cloth is typically wrapped around a 16mm diameter "finger" and held in place with a wire spring clip.  
  • Testing consists of rubbing it back and forth over the specimen surface.

The abradant supplied with the Taber® Linear Abraser and Reciprocating Abraser is referred to as a Wearaser®.  Comprised of silicon carbide or aluminum oxide abrasive particles embedded in a resilient or vitrified (clay) binder, the Wearasers are designed so the binder material breaks down during use - thus exposing and creating a new abrading surface.


Utilizing a proprietary formulation developed by Taber Industries, two general types of Wearasers are offered - Calibrase® (resilient identified by "CS" reference) and Calibrade® (non-resilient identified by "H" reference).  With standardized grades to meet varying requirements of abrasive action, many different types of material surfaces may be evaluated.  The quality and uniformity of the Wearasers is maintained by continuous inspection sampling and tightly controlled manufacturing processes.


The standard Wearaser has a diameter of 1/4" and is the size and shape of a pencil eraser.  This is secured in place with the Wearaser collet with approximately 0.100" exposed for testing.  Two other abradant configurations are also offered.  The Jumbo Wearaser has a 1/2" diameter (requires the Jumbo Wearaser collet assembly) and the Weardisc™ is a 3/4" diameter by 3/16" thick (requires the Universal Attachment).  Due to the larger contact area, both the use of the Jumbo Wearaser and Weardisc should be limited to flat specimens or samples that have little to no change in its shape / contour. Taber recommends applying the Weardisc to the Universal Attachment with pressure sensitive adhesive.


How long the abradant will last is dependent on the load, surface texture and frictional characteristics of the material being tested and frequency of refacing.
