Linear Abradants – Taber

Premium Abradants for Linear and Reciprocating Abraser Testing

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.

Product Configurations

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).

Calibrase Wearasers & Weardiscs

CS-6 Calibrase – Resilient Wearaser that produces slight abrading action. CS-8 Calibrase – Resilient Wearaser that produces mild abrading action, designed to operate under light loads. CS-10F Calibrase – Resilient Wearaser that produces moderate abrading action, designed to operate under light loads. CS-10 Calibrase – Resilient Wearaser that produces medium abrading action. CS-17 Calibrase – Resilient Wearaser that produces harsh abrading action. CS-19 Calibrase – Resilient Wearaser that produces severe abrading action.

Calibrade Wearasers & Weardiscs

H-10 Calibrade – A non-resilient, vitrified Wearaser that provides harsh abrading action. H-18 Calibrade – A non-resilient, vitrified Wearaser that provides a severe abrading action. H-22 Calibrade – A non-resilient, vitrified Wearaser produces a extreme abrading action. H-38 Calibrade – A non-resilient, vitrified abrading wheel that provides a medium abrading action. Comprised of very fine abrasive particles, similar to a polishing stone.

Specialty Wearasers

CS-2 Calibrase – Resilient Wearaser that has no abrasive material. CS-5 Calibrase – Resilient Wearaser that is comprised of densely compacted felt. CS-7 Calibrase – Similar to CS-5 but slightly harder for increased abrasion. H1 Felt – Resilient Wearaser that is comprised of densely compacted felt according to DIN 61200. Eraser – According to MIL 12397. Resilient Wearaser that produces very mild abrading action.

FAQ - Linear Abradants – Taber

What are Linear Abradants used for?

Linear Abradants, specifically Wearasers, are used with Taber Linear Abraser and Reciprocating Abraser instruments for abrasion testing. They evaluate material surfaces for wear resistance and abrasion characteristics across various industries.

What is the difference between Calibrase and Calibrade Wearasers?

Calibrase Wearasers are resilient (identified by "CS" reference) and have an expiration date, while Calibrade Wearasers are non-resilient, vitrified (identified by "H" reference) and do not have an expiration period. Each type offers different levels of abrading action.

What configurations are available for Linear Abradants?

Three main configurations are available: Standard Wearaser (1/4" diameter), Jumbo Wearaser (1/2" diameter), and Weardisc (3/4" diameter by 3/16" thick). Each requires specific collet assemblies or attachments.

How do Wearasers work during testing?

Wearasers are designed so the binder material breaks down during use, exposing and creating a new abrading surface. This ensures consistent abrasion throughout the test cycle and maintains testing accuracy.

What materials are used in Wearaser construction?

Wearasers are comprised of silicon carbide or aluminum oxide abrasive particles embedded in either a resilient or vitrified (clay) binder, utilizing proprietary formulations developed by Taber Industries.

Do Calibrase Wearasers require special handling?

Yes, Calibrase Wearasers should always be refaced with S-14 Refacing Strips before testing and should not be used after their expiration date due to possible deterioration. They may also need periodic refacing during testing if the surface becomes clogged.
