rubber bumper guard

Check whether a quoted rubber bumper guard will actually interface with the existing equipment. Medium, temperature and the mating face decide compatibility. Preference does not.

Existing machine face next to a rubber bumper guard sample

What has to be verified before an alternative is accepted

  • Mating face

    Measure the existing plate, stud pattern or adhesive land. A catalogue “guard” that misses the hole centres is a different part.

  • Mounting method and ASTM call

    Stud, through-bolt, weld plate or adhesive decides compatibility rather than preference. If the buyer asked for ASTM D2000, the report should cite the line call and the condition it was run under.

  • Shore A versus the struck surface

    A harder bumper can print paint. A softer bumper can take a set. Shore A stays on the elastomer scale; Shore D is the wrong instrument for this family.

  • Medium and temperature

    Oil, ozone, outdoor UV and heat belong with the compound question. Silicone first wins wide temperature and UV; FKM wins hydrocarbons. Neither is this desk’s default.

Compatibility axes grouped the way a factory answers them

The table is a question sheet. Values stay blank until the buyer or the named supplier writes them.

Grouped compatibility checks for a rubber bumper guard line
Group Ask Unit or pairing
Geometry Projection / thickness in or mm on the priced line
Geometry Width and footprint Finished contact face
Compound Shore A hardness Shore A, not Shore D
Compound Compression set % under ASTM D395 if crush repeats
Duty Operating temperature °F or °C with the medium
Duty Mounting method Stud, plate, adhesive or drawing
Files Named method ASTM D2000 or the buyer’s equivalent
Files Plant system ISO 9001 or IATF 16949 if requested

Documents that prove the interface, not the trading company

Dimensional page

The current drawing or dimensional sheet has to name the quoted guard. A family brochure does not stand in for hole centres.

Compound page

Shore A, compression set and the medium window belong to the quoted lot. A plant ISO badge does not replace that page.

Regulatory statements

REACH SVHC or RoHS statements, if required, name the quoted compound. Prop 65 wording is a California file ask, not a desk badge.

Substitution record

If the factory offers TPE / TPU instead of vulcanized rubber, re-issue the line. Heat deflection temperature and crosslinking density will not travel with the original approval.

Send the interface you can already measure

Missing hole centres or Shore A stay visible. This desk does not invent a close-enough cross.
