How to Choose the Right Stamped Bearing Housing for Your Equipment

Go Back

Choosing the correct stamped bearing housing is critical to stable operation, longer bearing life, and fewer failures. Selection is straightforward and can be completed using six criteria: load, environment, structure, accuracy, sealing, and bearing compatibility.


1. Select structure and thickness based on load
  • Light load, high speed, continuous operation: Standard-thickness stamped housing
  • Medium load, high vibration: Thickened steel stamped housing

  • Heavy load, severe shock: Stamped housings are not recommended; use cast iron or cast steel housings


2. Choose material and surface finish based on environment
  • Indoor, dry environment: Standard zinc-plated stamped housing
  • Humid, dusty, outdoor environment: Electrophoretic or plastic-sprayed stamped housing

  • Food, pharmaceutical, coastal, or highly corrosive environments: 304 or 316 stainless steel stamped housing


3. Match housing model to bearing type
The stamped housing must fit the bearing’s outer diameter and width:
  • UC, UK series insert bearings → PP, PF, PFC series stamped housings
  • Conveyor idler bearings → Idler-specific stamped housings

  • Agricultural machinery bearings → Square-bore or hexagonal-bore stamped housings


4. Select bore style based on shaft shape
  • Round shaft → Round bore stamped housing
  • Agricultural square shaft → Square bore stamped housing

  • Hexagonal shaft → Hexagonal bore stamped housing


5. Choose housing style based on installation space
Common styles:
  • Vertical housing (most widely used)
  • Diamond housing (high stability)

  • Round housing (compact equipment)


6. Select sealing configuration based on working conditions
For dusty or wet environments, choose stamped housings with 2RS sealing to effectively block dust, water, and mud from entering the bearing.
Proper selection can extend bearing and housing life by 50%–100% and significantly reduce equipment downtime.
