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
Exciter load
Use eccentric mass, eccentricity, speed and support geometry to establish cyclic bearing loads.
Exact bearing variant
Identify cylindrical or tapered bore, vibration-specific cage/internal design and clearance.
Mounting and lubrication
Check seating, shaft deflection, residual clearance and the specified oil/grease supply.
Which bearing structures make sense?
VA405 cylindrical-bore spherical rollers
Investigate records explicitly designated for vibratory applications.
Check first: The suffix does not by itself validate every exciter speed and load.
VA405 tapered-bore variants
Consider only where the shaft/sleeve and mounting design require them.
Check first: Mounting displacement and resulting clearance require the specified procedure.
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.
22320 EJA/VA405
100×215×73 mmVibration-specific design · cylindrical bore
The record explicitly describes vibratory duty, making this a relevant construction to investigate for an exciter.
- Dynamic C
- 847 kN
- Static C₀
- 950 kN
- Limiting speed
- 3000 rpm
Before selectionBoth records explicitly name vibratory applications; the tapered-bore option is not a direct installation substitute. Confirm cylindrical-bore installation, exact clearance, cyclic load and lubrication.

100×215×73 mmVibration-specific design · tapered bore
A tapered-bore vibration-specific reference for a separately specified shaft/sleeve installation.
- Dynamic C
- 847 kN
- Static C₀
- 950 kN
- Limiting speed
- 3000 rpm
Before selectionBoth records explicitly name vibratory applications; the tapered-bore option is not a direct installation substitute. Verify the taper/sleeve, mounting displacement and residual clearance; not a direct fit substitute for EJA.

— = not reported, or not directly comparable for a mounted unit. Width conventions differ for inserts, complete units and bearing assemblies; inspect the dimensional drawing. Values are read from the current BearingScope records, not estimated from model numbers.
Work through the selection
- Obtain the exciter drawing, operating speed and unbalance specification.
- Calculate cyclic reactions and verify the designated bearing construction.
- Check bore type, fit, residual clearance, lubrication and minimum-load requirements.
- Follow the approved mounting procedure and establish vibration/temperature baselines.
Symptoms worth checking
Cage distress
Investigate unsuitable bearing variant, load, lubrication and mounting.
Uneven heat at paired supports
Check alignment, residual clearance and lubricant delivery at both ends.
Symptoms are investigation prompts, not a diagnosis. Isolate equipment safely and follow its maintenance procedures before inspection.

Application questions, answered
Can an ordinary 22320 replace 22320 EJA/VA405?
Do not assume so. A vibration-specific design may differ in cage, internal geometry and clearance. Retain the specified full designation.
Are EJA and EKJA versions interchangeable?
The listed EKJA record has a tapered bore. Shaft, sleeve and mounting requirements differ; check the complete installation.
