User-friendly crusher liner epoxy with strength and consistency

Linebacker® Standard Crusher Liner Epoxy

For use in the majority of crushing applications with average strength ore, the Standard Crusher Liner Epoxy is designed for smaller cone crusher applications, typically crushing aggregates and other soft-to-medium hardness materials.

You have peace of mind that the uniform consistency, pourability and cured toughness assure support of cast wear parts operating under typical service conditions.


Compressive strength: 114 MPa (16,500 psi) ASTM D 695.


Linebacker® Heavy Duty Crusher Liner Epoxy

This heavy-duty option is the preferred backing material for tough, demanding or troublesome crushing applications such as those handled by gyratory and larger cone crushers. It is uniquely formulated for high-impact resistance, high compressive strength, and very low water absorption to ensure extra strength.


Compressive strength: 124 MPa (18,000 psi) ASTM D 695.


Linebacker® Cold Weather Crusher Liner Epoxy

Heavy duty backing material is featured in the Cold Weather Liner Epoxy so it’s suitable for tough, demanding, and troublesome crusher applications. Specifically for curing in cold temperature environments, it is suitable for use when air temperatures are between -4 to 16° C (25 to 60° F) with optimum pouring temperature between 7 to 13° C (45 to 55° F).


Compressive strength: 129 MPa (18,700 psi) ASTM D 695


Linebacker® Bushing Lock

We also offer Linebacker Bushing Lock, which is a specifically formulated product for locking bushings into position in all makes of gyratory and cone crushers.


None of the backing products contain VOCs, butyl glycidyl ether (BGE)¹ or nonyl phenol².


¹ Butyl Glycidyl Ether. The EPA (SARA Title III, section 312) lists it (BGE) as “toxic” (per ANSI Z129.1) by skin absorption and an immediate health hazard.


² Nonyl Phenol is a Marine Pollutant and considered “dangerous for the environment” per the EU directive 79/831/EEC.
