Find the Bearing for Your Requirement
Start with the full bearing designation, including suffixes. If the part number is unclear, provide the bore diameter, outside diameter and ring widths, together with photographs showing the bearing markings and construction.
For special-size bearings, a drawing is particularly useful: inner and outer ring widths may differ, and grooves or extended rings can affect the fit. A similar-looking bearing or matching main dimensions alone do not establish interchangeability.
Use the product catalogue to review individual models. For several items, send a purchasing list with a separate quantity for each designation.
What Are Deep Groove Ball Bearings Used For?
Deep groove ball bearings support radial loads and can accommodate axial loads in both directions within the limits of the particular design. They are used in equipment such as electric motors, conveying machinery and agricultural machinery.
Selecting a bearing for an application also requires checking speed, load, lubrication, operating temperature and the installation arrangement. A product's suggested application is a starting point for selection; final suitability depends on the exact bearing and operating conditions.
Check the Specification Before Ordering
Selection item |
Information to confirm |
Bearing identification |
Full designation, suffixes and any equipment or replacement reference |
Dimensions and geometry |
Bore, outside diameter, inner and outer ring widths, grooves and other special features |
Sealing arrangement |
Open, shielded or sealed construction, including the exact seal design |
Internal clearance |
Required clearance designation and the intended shaft/housing fits |
Precision requirements |
Applicable tolerance class and any application-specific acceptance criteria |
Operating conditions |
Speed, radial and axial loads, temperature, contamination and lubrication |
Order requirements |
Quantity per item, delivery destination, packaging and required delivery date |
For new equipment, include the bearing drawing or engineering specification. For replacement orders, keep all suffixes from the original bearing reference rather than using only the basic number.
Open, Shielded and Sealed Bearings
Open bearings have no integral seals or shields. Their suitability depends on the lubrication and protection provided by the equipment arrangement.
Shielded bearings use metal shields to help protect the internal components and retain lubricant. ZZ and 2Z are designations commonly encountered in supplier catalogues.
Sealed bearings use seals to help retain lubricant and exclude contaminants. Seal designs differ: contact, low-friction and non-contact designs do not have identical operating characteristics.
Suffix conventions vary between manufacturers. Confirm the construction shown in the drawing or product specification, and check availability for the exact model required.
Prepare an Enquiry for Your Purchasing Process
For distributors and wholesalers: send an itemised list with quantities per model, preferred packaging, destination and any labelling requirements. If the order covers repeat replenishment, include the expected ordering frequency.
For equipment manufacturers: provide the drawing revision, working conditions and inspection or sample-approval requirements. State which technical characteristics must remain consistent between the approved sample and subsequent orders.
For aftermarket and maintenance buyers: provide the existing bearing designation, equipment reference and relevant photos. Where the original specification is unavailable, identify which dimensions and operating details still need checking.
Before placing an order, agree on the final specification and quotation details, including quantity, MOQ, lead time, packaging and the documents required for acceptance. Where sample approval is needed, define the approval criteria before bulk procurement.
Frequently Asked Questions
Can I choose a replacement by dimensions alone?
No. Matching the bore, outside diameter and width is only part of the assessment. Ring geometry, clearance, sealing, tolerances and operating requirements also need to match the application. Include the original designation and available technical information in your enquiry.
What should I send if I cannot identify the bearing number?
Send clear photographs of both sides and any markings, together with measured bore, outside diameter and ring widths. Include the equipment model or a drawing where available. Photographs help identification, but they do not establish internal specifications on their own.
How should I request a quotation for multiple models?
List each complete bearing designation on a separate line with its quantity. Add packaging requirements, delivery destination and the required delivery date. This makes it easier to assess each item and compare the resulting quotation.
How do I confirm MOQ, samples and lead time?
Include your requested quantity and any sample requirement in the enquiry. Ask for confirmation for each model and configuration, including whether the quotation covers available stock or production. Confirm the agreed schedule before placing the order.
What quality information should be agreed before purchase?
Identify the documents and acceptance checks your purchasing process requires, such as an approved drawing, dimensional results, material information or specified noise and vibration limits. Confirm which records apply to the quoted product and how they will be supplied before approving the order.
