Technical Library

Material selection, tolerance interpretation and failure analysis, written for the engineer specifying the part.

Planned articles

This section is the long-term search asset. One analysis of a million newly published pages found that only about 1.7 per cent reach the top ten results within a year, which is precisely why technical content has to start early and continue without interruption rather than be commissioned in a burst.

Hydraulic cylinder components

  • Honed bore or skived and roller burnished: choosing by length-to-bore ratio
  • Reading a rod specification: chrome thickness, HV hardness and what each protects against
  • Induction hardening case depth and why hardness alone is not a specification
  • Salt spray hours in ISO 9227 AASS and what a nickel underlayer actually buys
  • Seal housing dimensions: why the groove radius matters as much as the width
  • EN 10305-1 E355, DIN 2391 ST52 and SAE 1026 compared
  • Distortion in welded cylinder assemblies and the correct machining sequence

Hydraulic Breaker parts

  • Tool diameter as the primary key of a breaker spare parts catalogue
  • Why through bolts must be thread rolled rather than turned
  • Reading breaker wear: what a worn bushing tells you about the front head
  • Dual-hardness chisels and cold-climate fracture
  • Piston land geometry and its effect on impact energy
  • Cleanliness in rebuilt breaker bodies: cross-hole deburring and washing
