Rectangular Slide Assembly Carriage With Linear Motion Guide Rail and Exposed Bearing Elements

Aerospace actuator stages, automotive test-bench slides, and military sensor positioning systems use a linear motion guide rail where rail straightness and bearing surface Ra together determine carriage travel accuracy and rolling element wear rate; straightness deviation above 0.01 mm per 100 mm introduces a periodic positioning error that accumulates over travel length, while Ra above 0.4 μm on the bearing race surface increases contact stress and accelerates fatigue spalling. Chongqing Jiangjin Changfeng Precision Machining (Chongqing, established 2001, Degan Industrial Park) mills this rectangular slide carriage linear motion guide rail using 5-axis milling and boring & milling at their approximately 20,000 m² Chongqing facility, with rail straightness, bearing surface Ra, and mounting hole positions measured against your released dimensions at the first article stage. ISO 9001 certification covers aerospace, automotive, and military linear motion guide rail applications. Include rail straightness tolerance, bearing surface Ra, mounting hole pattern, and material specification in your RFQ package. For a machining detailed pricing from our chongqing team.
