定义
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.
工作原理
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.
材料
Typically made from hardened steel (e.g.AISI 52100440C)stainless steel (e.g.304316)aluminum alloys (e.g.6061-T6)or engineered polymers (e.g.POMPTFE composites) depending on loadspeedand environmental requirements.
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
标准
ISO 14728DIN 636
