Frequently Asked Questions
Q: What is the difference between 6700ZZ and 6700-2RS bearings?
A: The 6700ZZ features double-sided steel shields that protect against dust and light debris, making them great for dry, high-speed applications. The 6700-2RS uses double-sided rubber seals for better retention of lubrication grease and improved resistance to moisture — ideal for slightly wet or contaminated environments. Both share the same 10×15×4mm dimensions and can be used interchangeably where sealing requirements allow.
Q: What applications are the 6700 miniature deep groove ball bearings suitable for?
A: These 6700 series bearings with a 10mm inner bore are widely used in RC vehicles, drones, 3D printers, small electric motors, robotics, inline skates, computer cooling fans, and various precision equipment repairs. Their compact 15mm outer diameter and 4mm width make them an excellent choice wherever a slim, low-friction rotating component is needed.
Q: How many bearings come in one order?
A: Each order includes 10 pieces of the selected bearing type (ZZ or 2RS). This pack size is ideal for bulk repairs, workshop stock, or multi-unit builds where having spare bearings on hand saves time and cost.
Q: Are these bearings pre-lubricated?
A: The 2RS rubber-sealed variants are pre-packed with grease and are sealed to retain lubrication throughout their service life. The ZZ steel-shielded bearings are lightly lubricated at the factory; for demanding applications, additional lubrication through the shield gap may extend service intervals.
