Design, applications and model references

A single-row four-point contact ball arrangement can support combined axial, radial and overturning moment loads when properly sized.

Design & available configuration

Internal gear, external gear and gearless layouts may be evaluated against the mounting arrangement. For a particular model, EIM should confirm its designation, dimensions, internal design and applicable tolerances before a specification is accepted.

Where this series is used

Rotation platforms, lifting equipment and positioning assemblies. The exact choice depends on the load spectrum, duty cycle and mechanical interfaces rather than the series name alone.

slewing bearing load evaluation

slewing bearings require checks for overturning moment, radial and axial loading, bolt pattern, ring deformation and operating duty. Supplier selection also requires attention to service conditions, inspection requirements and the condition of mating components.

Technical parameters & model table

Reviewed dimensional and performance values will appear here after EIM technical approval. The original spreadsheet references are held internally and are not a guarantee of inventory, interchangeability or performance.

What to include in your RFQ

  • Complete series or model designation, including suffixes if applicable.
  • Raceway diameter, mounting pattern, gear arrangement, load cases and operating duty.
  • Required quantity, delivery location and desired schedule.
  • If you have a PDF or CAD drawing, email it directly to service@eimbearing.com.

Selection FAQ

Can I order using only the series name?

A series name narrows the product family, but final quotation usually requires a full model designation or a drawing and operating data.

Can another manufacturer’s designation be substituted?

Possible interchangeability must be checked against dimensions, construction, tolerances, internal clearance and application duty. A matching name alone is not enough.

How do I request a custom size?

Send mounting dimensions, load directions, rotational speed and annual quantity. Use email for drawings; this website does not accept file uploads.

Technical Selection & RFQ Information

Check axial and radial loads together with the overturning moment, ring mounting dimensions and gear arrangement before selecting a slewing-bearing design.

This series has 1 source specification worksheet(s) in the EIM 10.9 technical file set. A series-specific product photograph is available in the source folder but requires matching verification.

Models Listed in the Supplied Source

010-30-500, 011-30-500, 013-30-500, 012-30-500, 014-30-500. These are source designations, not an availability commitment; confirm the matching specification row before ordering.

What to Send for a Quotation

Include the full bearing or bushing designation (including suffix), working dimensions, operating load and speed, expected quantity, and any relevant fit, tolerance, sealing or material requirements. Send confidential drawings separately by email.

All technical figures must be checked against the selected source table and current application conditions before purchasing.

Ordering questions

Frequently asked questions

Can I request this series using only a model number?

Yes. Include the complete model code with suffixes and the expected quantity. Additional dimensions or application details may be needed for confirmation.

Can EIM confirm a replacement for another bearing brand?

Provide the original designation and relevant specifications. Fit, clearance, internal design, duty conditions and any other critical differences must be checked before an alternative is confirmed.

How do I send my drawings?

Email PDF, STEP, DWG or other technical files to service@eimbearing.com. You can send your files directly by email.

Are all models in this family available from stock?

Availability is checked per exact designation and quantity. Stock availability depends on the exact model and order quantity.
