Material & Certification

A slide bar (also called a guide strip or feed beam liner) is a precision-machined steel component that lines the feed beam channel of a rock drilling machine. It guides the drill drifter (rock drill unit) in precise linear motion during drilling, collaring, and retraction.

Common failure modes: Abrasive wear from rock dust contamination, scoring from inadequate lubrication, fretting corrosion from vibration, deformation from impact loading.

This part is produced under an ISO 9001:2015 certified quality management system. Dimensional verification and functional testing are performed on every batch. Certificate of conformance available on request.

Rubber Material Specification & Testing Standards

Feed beam slide bars for Sandvik rock drilling equipment are precision-machined from tool steel (typically 1.2379 / D2 grade or equivalent) hardened to HRC 58–62 for wear resistance against rock-dust-contaminated lubrication. In aggressive underground environments, stainless steel grades (316L or similar) are specified for corrosion resistance, accepting a slight reduction in surface hardness in exchange for chemical stability in wet, acid-generating rock environments.

Surface finish is critical to lubrication film formation and stick-slip prevention: ground surfaces at Ra 0.4–0.8 μm maintain adequate oil film thickness between bar and channel. Dimensional tolerances of h6 (ISO 286) on bar width ensure correct fit within the feed beam channel with sufficient clearance for lubrication film without excessive lateral play. Deviations from this tolerance cause uneven drifter guidance, steering drift during drilling, and accelerated asymmetric wear on one bar face.

Lubrication compatibility must be verified against the Sandvik specification for your machine. Rock dust-contaminated grease becomes an abrasive compound that accelerates both slide bar and feed beam channel wear simultaneously. Automated centralised lubrication systems that deliver small, frequent grease doses outperform manual greasing intervals, maintaining consistent film thickness and diluting contamination before it concentrates.

Environmental Operating Limits

This component is rated for continuous operation within the following environmental envelope: temperature range −40°C to +100°C ambient, ozone resistance per ASTM D1149, UV exposure resistance per ASTM D4329. For operation consistently above 40°C ambient — desert or tropical sites — confirm the specific high-temperature compound variant with the Sandvik parts department for your machine serial number range.

Chemical compatibility: rated for water, mineral oil splash, and light fuel contact. Not rated for continuous immersion in hydraulic fluids, aromatic solvents, or biodiesel above B20 concentration. Specify unusual chemical exposure conditions when ordering so the correct compound can be confirmed before dispatch.

Batch Certification & Quality Traceability

All 55017281 units are produced under ISO 9001:2015 quality management. Each production batch undergoes dimensional inspection, Shore A hardness verification (ASTM D2240), and adhesion testing (ASTM D429 for bonded parts). Certificate of conformance (CoC) is available on request, identifying production batch, test results, and applicable OEM standard. Traceability marking on each component allows full trace-back to production date, compound batch, and test records.

Request CoC documentation when ordering — provided at no additional cost and essential for fleet warranty management.
