Detailed Engineering Specifications

Designed for demanding industrial environments, this deep groove ball bearing features an inside diameter of 21mm, an outside diameter of 163mm, and a width of 31mm. Constructed from Aluminum 6061-T6, known for its excellent corrosion resistance and moderate strength-to-weight ratio, it is ideal for applications where exposure to moisture, chemicals, or saltwater is a concern. This material also offers good thermal conductivity, aiding in heat dissipation. The bearing's design allows it to accommodate moderate radial loads and axial loads in both directions, making it suitable for machinery in food processing, marine, chemical, and light manufacturing sectors.

Installation Procedure

1. Ensure bearing bore and shaft are clean and free of debris. 2. Apply a light coating of appropriate lubricant to the shaft and inner ring. 3. Carefully press the bearing onto the shaft, ensuring it is seated squarely and fully. 4. Install the housing, ensuring proper alignment with the bearing. 5. Secure the bearing in the housing according to manufacturer specifications, avoiding excessive force.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Forcing the bearing onto the shaft with impact, leading to brinelling or damage to the raceways.Use a proper bearing installation tool or a controlled hydraulic press to apply force evenly to the inner ring only.
Incorrect lubrication, either insufficient or using the wrong type of lubricant, leading to premature wear.Consult the lubricant manufacturer's recommendations for this specific bearing size and operating conditions. Ensure proper fill levels.
Misalignment during installation, causing uneven load distribution and premature bearing failure.Verify that both the shaft and housing are perfectly aligned before and during the pressing operation.

Common Applications

  • Conveyor systems in corrosive environments
  • Pumps and mixers in chemical processing
  • Marine equipment and winches
  • Food and beverage processing machinery
  • Light-duty industrial automation

⚠️ Engineering Warnings

  • Aluminum 6061 has lower tensile strength than steel; avoid applications requiring extreme load-bearing capacity.
  • While corrosion-resistant, prolonged immersion in aggressive chemicals may still degrade the material. Verify chemical compatibility.
  • Ensure proper shaft and housing tolerances are maintained to prevent premature wear or seizure.
