🎯 What You Get ------ In this kit, you will get 60Pcs 6 Sizes Ball Bearings. 6 types are 3×8×4-693ZZ, 3×10×4-623ZZ, 4×13×5-624ZZ, 5×11×5-685ZZ, 7×14×5-687ZZ, 7×22×7-627ZZ. 10Pcs of each size. you can find the right bearing in our kit. Bearings are pre-lubricated, and easy to maintain.
🎯 High Quality ------ Made of carbon steel, these deep-groove bearings offer excellent durability and resistance to deformation under heavy loads. Absorb vibration and impact, reduce noise, reduce energy loss and improve transmission efficiency. Pre-lubricated, suitable for low-demand applications in the long term.
🎯 Pre-Lubricated ------ Ball bearings keep the lubricant inside, ensuring smooth operation and reducing the need for frequent maintenance and making them easy to maintain. You also can reapply lubricant as needed to promote longevity.
🎯 6 Size Options ------ We have prepared 6 size ball bearings. Each bearing has its unique inner diameter, outer diameter, and thickness, making them suitable for different applications. Our bearings run smoothly. Saves you time and energy, as you don't have to search for different bearings separately.
🎯 Wide Applications ------ This component is manufactured from carbon steel with an untreated, jet-black exterior. Designed for low-speed operation under 200 RPM, it features an inner bore with a machining tolerance of ±0.08mm. It is well-suited for low-demand applications such as slow-speed transmission equipment, casters, and toy vehicles.
