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
Cleaning exposure
Record temperature, pressure, chemicals, spray direction and cleaning frequency.
Hygiene zone
Distinguish dry, splash and potential food-contact positions and the site's specified lubricant requirements.
Housing design
Check accessible surfaces, drainage, crevices, sealing and compatible fasteners.
Which bearing structures make sense?
Stainless rolling bearings
A material starting point for corrosion-sensitive supports.
Check first: Verify chemical resistance, seals and lubricant; stainless is not universally corrosion-proof.
Hygienic mounted units
Evaluate the whole housing/seal/insert system.
Check first: An ordinary pillow block is not automatically a hygienic unit.
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.
W 6205
25×52×15 mmStainless deep-groove bearing · open construction
A material and envelope starting point when corrosion resistance is part of the support specification.
- Dynamic C
- 11.7 kN
- Static C₀
- 7.65 kN
- Limiting speed
- 19000 rpm
Before selectionStainless material references only; these records do not establish food-contact, hygienic-unit or pressure-wash approval. Check exact materials, chemicals, lubrication and external sealing. Open construction is not waterproof.

— = 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
- Document the actual hygiene zone and cleaning regime.
- Resolve support loads and select a compatible bearing/housing layout.
- Verify materials, seals, lubricant and cleanability for that zone.
- Validate cleaning and maintenance procedures for the assembled line.
Symptoms worth checking
Corrosion after washdown
Check chemical compatibility and retained cleaning liquid.
Grease leakage into a process area
Review sealing, grease amount and the approved hygienic design.
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
Does stainless steel mean food-safe?
No. The complete assembly, lubricant and intended exposure must meet the applicable food-process requirements.
Does 2RS1 mean pressure-wash proof?
No. An integral seal designation is not a blanket approval for pressure jets, immersion or cleaning chemicals.
