• This package includes 30 pieces of 693ZZ bearings—high-performance small ball bearings designed for daily maintenance and mechanical assembly needs. As practical mini bearings, they effectively solve the problem of worn or damaged bearings in various small mechanical equipment, providing a cost-effective and sufficient replacement solution for both personal and professional use.
• Each 693ZZ bearing has accurate dimensions: Inner Diameter = 3 mm, Outer Diameter = 8 mm, Thickness = 4 mm—exactly matching the size requirement of 4mm ball bearing for specific equipment. The bearings are made of carbon steel, which ensures excellent durability, strong deformation resistance under heavy loads, and easy installation and removal. Whether you’re replacing old bearings or assembling new devices, the stable material and precise size can save you time and effort.
• These small ball bearings feature low-noise and Tolerance precision, ensuring smooth operation without annoying noise. Meanwhile, they have outstanding high-temperature resistance, which allows them to work normally even in high-temperature environments—avoiding performance degradation or damage caused by overheating. The high-precision design also enables the bearings to support both radial and axial loads, greatly improving the operating efficiency of the equipment they’re installed in.
• Each 693ZZ bearing is equipped with shields on both sides, which can effectively block dust, debris, and other impurities from entering the bearing interior. This dust-proof design not only extends the service life of the bearings but also ensures smoother and quieter operation during high-speed rotation. Whether it’s the fast spinning of skateboard wheels or the continuous operation of electric motors, these bearings can maintain stable performance.
• As multi-functional mini bearings, they have a wide range of applicable scenarios. They are perfect for bicycle wheel bearing replacement, ensuring smooth riding
• suitable for trolleys to reduce friction and make pushing easier
• ideal for skateboard wheels to enhance sliding stability
• also applicable to lawnmowers and electric motors to maintain normal mechanical operation.
