Keep the evidence with the model shortlist
The models on this page illustrate bearing roles; they are not confirmed replacements for an unspecified machine. Keep the original complete marking, machine position, load and speed duty, temperature, lubricant and mounting arrangement together. Check the candidate's recorded values below and leave unreported parameters unknown.

What matters in this application
Crusher support
Determine load peaks, eccentric drive forces, speed and housing rigidity from the machine design.
Mill support architecture
Identify rolling bearings versus white-metal/plain trunnion bearings or slide shoes before selecting a method.
Contamination control
Assess dust exclusion, lubricant delivery, filtration and maintenance access across the entire housing.
Which bearing structures make sense?
Spherical roller supports
Investigate for radial-heavy supports that need angular accommodation.
Check first: Check shock/static safety, residual clearance and the actual permissible misalignment.
Plain trunnion or slide-shoe supports
Use the mill's pressure, speed, lubrication and thermal design.
Check first: A rolling-bearing L10 calculation does not validate a hydrodynamic support.
Recommended starting points
These candidates illustrate specific roles and envelopes, not a ranked list or interchangeable set. Review each condition before using a model in a design.

Work through the selection
- Identify the support architecture and original drawing.
- Build load cases including start-up, impacts, stoppages and the normal duty cycle.
- Check support stiffness, lubricant delivery and the correct life or film-bearing method.
- Inspect seats, seals and monitoring data during the equipment's approved service process.
Symptoms worth checking
Edge distress
Investigate shaft deflection, housing alignment and uneven support.
Scored or contaminated surfaces
Trace the lubricant supply and contamination source instead of changing only the bearing.
Symptoms are investigation prompts, not a diagnosis. Isolate equipment safely and follow its maintenance procedures before inspection.
Have the original designation?
Look up the complete model and suffix before comparing potential alternatives.
Application questions, answered
Can a ball-mill trunnion bearing be replaced with a catalogue roller bearing?
Not as a simple substitution. Plain and rolling systems have different geometry, lubrication, stiffness and thermal behavior.
Does a high dynamic rating cover crusher impact loads?
No. Assess shock peaks, static safety and the complete housing/shaft support as well as fatigue life.
