RE30035 Crossed Roller Bearing - FAQ
How is the RE30035 tested before delivery?
Each bearing undergoes 100% inspection for dimensional accuracy, smooth rotation, noise level, and preload verification. This ensures that every unit meets the precision grade ordered (P5, P4, or P2).
How is the RE30035 packaged for shipping?
Each bearing is individually vacuum-packed in anti-rust film, cushioned with foam, and placed in reinforced cartons or wooden cases for export. This ensures safe and contamination-free delivery worldwide.
What materials are used in the RE30035 bearing?
The bearing rings and rollers are manufactured from high-carbon chromium bearing steel, heat-treated for hardness and fatigue resistance. Optional surface treatments can be applied for corrosion resistance or special operating environments.
How does thermal expansion affect bearing clearance?
Temperature changes can alter internal clearance and preload. In precision systems, thermal effects should be considered during design to prevent excessive preload or loss of stiffness during operation.
