Definition of Thin Wall Deep Groove Ball Bearings：

Thin-Wall Deep Groove Ball Bearing is a type of bearing that is lightweight and compact by optimizing the wall thickness design. Its basic structure is similar to that of ordinary deep groove ball bearings, consisting of an inner ring, an outer ring, a steel ball and a cage, but by reducing the thickness of the inner and outer rings (usually the wall thickness is only 30%-50% of that of standard bearings), the overall weight and space occupied are significantly reduced. This type of bearing is designed for equipment that is sensitive to installation space, such as industrial robot joints or micro motors, while maintaining the radial and axial composite load-bearing capacity of deep groove ball bearings 

 

Core Features
Thin-wall design:

  • Through material optimization (such as high-carbon chromium steel, stainless steel) and precision machining technology to reduce wall thickness, reduce weight and save space.
  • Typical wall thickness range: 0.5mm to 5mm (depending on the specific model).

 

Deep groove structure:

  • The arc-shaped deep grooves on the inner and outer rings evenly distribute the load and can withstand radial force and a certain axial force (bidirectional axial load) at the same time.

 

High precision and low friction:

  • Adopt high-precision grinding technology to ensure smooth rotation, suitable for high-speed scenarios (such as micro motors).

Sealing and lubrication:

  • Optional rubber seals (RS/2RS) or metal dust covers (ZZ/2Z) to prevent contaminants from intruding and extend service life.

 

Main application areas

  • Industrial robots: mechanical arm joints and rotary tables to meet the requirements of lightweight and high precision.
  • Medical equipment: MRI machines (non-magnetic stainless steel), surgical robots to avoid electromagnetic interference.
  • Aerospace: UAV servos and satellite antenna drive mechanisms to adapt to extremely compact spaces.
  • Consumer electronics: UAV gimbals and smart home motors to support miniaturized design.
