Case Study: Precision Spindle Assembly for an Industrial Encoder

AST goes beyond supplying standard bearings, providing precision mechanical sub-assemblies. We specialize in assemblies that incorporate precision bearings and components manufactured to the most exacting specifications.

One example was a request to provide a customer with a precision spindle assembly for an industrial encoder. An encoder is a position sensing device. They are used to sense rotary motion and provide feedback – via an electrical signal – to a processor, controller or computer. This makes them key components in automated machinery and test systems in conjunction with friction and measuring wheels, ball screws, timing pullies, rack and pinion actuation, etc.

Assembly Details:

  • Bearings: Two stainless steel ball bearings, ABEC-7 precision with 2 shields and bonded under a pre-load.
  • Shaft and Housing: Both made of stainless steel.
  • Lubrication: Lubricated with a special grease for low noise and increased life
  • End Result: An extremely precise running geometry

AST can conduct design reviews and provide assemblies manufactured to your specifications. Our highly skilled technicians know the correct way to handle and install bearings, and can provide you with a more reliable assembly at a significant cost savings.
