SANJ / FAQ
Bearing Questions, Answered
Practical answers on bearing dimensions, model designations, manufacturer enquiries, reference specifications and product configuration.
Answers to common bearing identification and sourcing questions.
How do I identify a bearing size?
Read the full designation and check bore d, outside diameter D and width B or overall width T. A matching size is the start of identification; internal design and suffixes also matter.
Are SANJ catalog ratings approved SANJ performance values?
The current catalog clearly identifies source-specific reference ratings. The final SANJ configuration, material, tolerances and performance must be agreed in a quotation and approved datasheet.
Which bearing family should I choose?
Start with load direction, speed, alignment, stiffness and the shaft arrangement. Use the engineering guides to prepare the brief, then confirm selection against the complete operating duty.
What should I include in a quotation request?
Include the full designation or drawing, quantity, destination, application, loads, speed, temperature, sealing, clearance, lubrication and any inspection or packing requirement.
Are the photographs the exact SANJ product?
Product reference images come from authorized source websites. Some have AI-assisted background and marking cleanup, which is stated beside the image. Sources may reuse a family image across models. Seal, cage, material and internal configuration may differ from SANJ supply. Banner concepts and dimension schematics are explicitly labeled.
Can I order directly online?
This is a B2B enquiry catalog. Pricing, availability, delivery and the final supply specification are confirmed through a quotation, rather than an online checkout.
Where can I download dimensions?
Each product page includes a reference data CSV. The Downloads page provides a consolidated 200-model catalog with source links.
