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
Bearing temperature
Establish the actual ring temperature, thermal gradients and heating/cooling cycle.
Motion and load
Record rotation, dwell, starts, loads and the permissible speed for the exact high-temperature design.
Complete construction
Confirm lubricant system, cage, shields, clearance and dimensional stability together.
Which bearing structures make sense?
VA201 high-temperature designs
Investigate where their exact catalogue operating conditions suit the machine.
Check first: Do not transfer a standard 6205 speed rating to this variant.
VA228 high-temperature designs
Compare the specific construction and lubrication requirements with the duty.
Check first: Different high-temperature suffixes are not universal substitutes.
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.
6205-2Z/VA201
25×52×15 mmHigh-temperature construction · 25 mm bore
The record explicitly identifies a high-temperature bearing with shields on both sides.
- Dynamic C
- — kN
- Static C₀
- 7.8 kN
- Limiting speed
- 120 rpm
Before selectionTemperature-specific records, not blanket approval for an oven temperature or conveyor speed. Use the exact VA201 temperature, lubrication and speed instructions, not the ordinary 6205 limits.

Different sizes and bearing structures are shown for different duties. C and C₀ are catalogue load ratings, not permissible equipment loads. Limiting speed is not an approved operating speed.

— = 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
- Measure or establish actual bearing temperatures throughout the cycle.
- Select a complete high-temperature construction and check its exact speed/load limits.
- Evaluate thermal expansion, fits and operating clearance.
- Follow the maker's mounting and lubrication instructions; monitor temperature under the intended load.
Symptoms worth checking
Lubricant leakage or deposits
Review the selected lubrication system and actual temperature.
Seizure during heat-up
Investigate thermal growth, fits and clearance rather than simply choosing more grease.
Symptoms are investigation prompts, not a diagnosis. Isolate equipment safely and follow its maintenance procedures before inspection.
Have the original designation?

Application questions, answered
Can high-temperature grease turn an ordinary bearing into VA201?
No. The complete construction, clearance and material/temperature specifications matter.
Can I use the normal 6205 limiting speed for VA228?
No. Use the exact high-temperature variant's data. Missing values must not be filled from a standard bearing.
