Product Introduction

The 61816 (also categorized under the 6816 series) is a precision thin-section deep groove ball bearing designed for applications where space and weight savings are crucial. Measuring 80 x 100 x 10 mm, this bearing features an extremely small cross-section relative to its shaft diameter, enabling compact structural designs without sacrificing rotational accuracy. Manufactured in our high-precision production center, the 61816 utilizes vacuum-degassed GCr15 steel and ultra-smooth ground raceways. Our strict quality laboratory tests every batch for low torque, low noise (Z2V2/Z3V3), and high concentricity, providing our global B2B clients with an ideal component for high-precision, space-restricted mechanisms.

Applications

Industrial robotics arms and joint actuators.
Precision medical imaging equipment and optical rotary tables.
Aerospace instrumentation, encoders, and automation equipment.

FAQ

Q: What is the main difference between 61816 and 6816?
A: They are identical in dimensions (80x100x10mm); 61816 is the standard ISO designation, while 6816 is the equivalent designation used by many Japanese manufacturers.
Q: Can this bearing support heavy radial loads?
A: Thin-section bearings prioritize spatial efficiency and light-to-moderate loads. For extremely heavy radial loads, a standard 6016 or 6216 series should be considered.
