Product Q&A
Q:What are the exact dimensions of the 6706 thin section bearing?
A:
The 6706 bearing has metric dimensions of 30mm (inner diameter) * 37mm (outer diameter) * 4mm (width). It's an ultra-thin section bearing with only 4mm thickness, making it ideal for space-constrained applications like cooling tower fans and compact machinery.
Q:What is the maximum speed rating for the 6706 ball bearing?
A:
Our high-precision 6706 bearings can achieve a limit speed of up to 18,000 RPM with grease lubrication and 22,000 RPM with oil lubrication. The thin section design reduces friction and heat generation, making it perfect for high-speed cooling fans and HVAC applications.
Q:What are the advantages of thin section bearings like the 6706?
A:
Thin section bearings like the 6706 offer several advantages: 1) Space-saving design with only 4mm width saves 60% space vs standard bearings, 2) Lower weight reduces rotating mass, 3) Reduced friction for higher efficiency, 4) Suitable for compact designs in cooling towers, office equipment, and precision instruments without sacrificing load capacity.
Q:Can the 6706 bearing be used in cooling tower fans and HVAC systems?
A:
Yes, the 6706 bearing is specifically designed for cooling tower fans, HVAC systems, and ventilation equipment. Its low vibration (Z1-Z4 levels available), high-speed capability, and ultra-thin 30x37x4mm design make it ideal for smooth, quiet operation in temperature control and air circulation applications.
Q:What materials and certifications do Welink 6706 bearings have?
A:
Our 6706 bearings are manufactured from premium GCr15 chrome steel or stainless steel 440C for corrosion resistance. The cage is available in steel, nylon, or brass. All bearings are ISO9001 certified, SGS tested, and RoHS compliant. We offer precision grades from P0 to P4 with various clearance options (C0/C3/C4/C5) to meet your specific requirements.
