Component Specifications

Definition
The bearing housing cavity is a critical structural feature within linear bearing blocks, designed to precisely accommodate and secure rolling elements (such as balls or rollers) and their retainers. This cavity maintains proper alignment, distributes loads evenly, and provides lubrication channels to ensure minimal friction and wear during linear motion applications in industrial machinery.
Working Principle
The cavity creates a controlled environment where rolling elements circulate under load, converting sliding friction into rolling friction. This reduces energy loss, heat generation, and wear while maintaining precise linear guidance along shafts or rails.
Materials
Typically made from hardened steel (e.g., AISI 52100, 440C), stainless steel (e.g., 304, 316), aluminum alloys (e.g., 6061-T6), or engineered polymers (e.g., POM, PTFE composites) depending on load, speed, and environmental requirements.
Technical Parameters
  • Hardness 58-62 HRC (steel)
  • Load Capacity Dynamic: 5-50 kN, Static: 10-100 kN
  • Surface Finish Ra 0.4-1.6 μm
  • Cavity Diameter 10-100 mm
  • Roundness Tolerance ≤0.005 mm
Standards
ISO 14728, DIN 636
