Wear parts

Bits, Drill Strings, Rock-Drill Front Ends, Bolting Units, Feeds and Pivot Wear Areas

Material links support engineering selection of ANRANST replacement parts; they do not imply one OEM material across all Boltec machines. Confirm the choice using rock properties, impact, threads, grout medium, support method, failure mode, used-part inspection and drawing requirements.

Bolt-Hole Bits and Carbide Buttons

Rock-bolt Drill Bits & Carbide Buttons

Bits directly face impact, rotation, abrasion and flushing media. Check hole diameter, thread, face design, button layout, flushing, rock properties and COP RR11, RR14 or COP 628 configuration together.

Material assessment: Assess tungsten-carbide grades for the buttons. The steel body must balance impact toughness, thread fatigue resistance and surface wear resistance. Confirm the selection from the original part, catalogue number and failure mode.

Shank Adapters, Couplings, Rods and Guide Tubes

Shank Adapters, Couplings, Rods & Guide Tubes

The shank adapter transfers rock-drill impact and torque into the drill string; couplings, rods and guide tubes transmit energy and maintain hole direction. Check the rock drill, thread system, rod diameter, length, flushing hole, end geometry and wear location.

Material assessment: Drill-string parts generally require fatigue-resistant alloy steel, controlled heat treatment and surface strengthening. Thread geometry, concentricity, straightness and core toughness are as important as the material itself.

Wear Pairs at Boom, Mesh-Handler and Stabilizer Pivots

Boom, Mesh-handler & Jack Pivot Wear Pairs

Pins, bushings, thrust parts and telescopic guides in the boom, optional mesh handler and stabilizers face alternating bending, impact and sliding wear. Check BUT 45 or the specific arm, left/right position, shaft diameter, length, lubrication grooves, housing bore and clearance.

Material assessment: Assess strong, tough alloy steels and surface strengthening for pins. Bushings follow the original copper-alloy, bearing-steel or sliding-composite design; hardness alone cannot replace complete fit verification.
