🎯 What You Get ------ In this kit, you will receive 60 pieces of ball bearings in 6 sizes. The 6 types are 3×8×4-693ZZ, 3×10×4-623ZZ, 4×13×5-624ZZ, 5×11×5-685ZZ, 7×14×5-687ZZ, and 7×22×7-627ZZ. There are 10 pieces of each size, so you can find the right bearing for your needs in our kit. The 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 vibrations and impacts, reduce noise, minimize energy loss, and improve transmission efficiency.
🎯 Pre-lubricated ------ The ball bearings retain lubricant, ensuring smooth operation and reducing the need for frequent maintenance, making them easy to service. You can also reapply lubricant as needed to promote longevity.
🎯 6 Size Options ------ We offer 6 different sizes of ball bearings. Each bearing has its own unique inner diameter, outer diameter, and thickness, making them suitable for various applications. Our bearings operate smoothly. You save time and energy because you don't have to search for different bearings separately.
🎯 Wide Applications ------ This component is made of carbon steel with a black, unmachined outer surface. Designed for rotational speeds below 200 RPM, the inner diameter has a machining tolerance of ±0.08 mm. It is suitable for undemanding applications such as slow-speed equipment, casters, and children's toy cars.
