What information do you need to recommend a suitable bearing?
If you already have a bearing number, send us the model directly. For new or non-standard applications, it is better to provide the bore diameter, outside diameter, width, load, operating speed, temperature, lubrication, sealing requirements and application equipment. A drawing or existing bearing sample can make the evaluation more accurate.
Can BMT manufacture non-standard or customized bearings?
Yes. BMT supports customized bearing development based on customer drawings, samples and application requirements. The technical team can evaluate the bearing structure and specifications before sample production.
Can I get samples before placing a bulk order?
Yes. For customized projects, samples can be arranged after the technical specifications are confirmed. Customers can use the samples for dimensional checks, assembly verification and application testing before mass production.
What industries are BMT bearings used in?
BMT bearings are supplied for automotive, motorcycle, industrial equipment, agricultural machinery, motors, pumps, household appliances, robotics and automation, and other rotating equipment applications.
What quality standards and certifications does BMT have?
BMT's manufacturing operations use quality management and inspection processes supported by professional measuring and testing equipment. The company has ISO9001 and IATF 16949-related quality certification records. For current certification status, customers can request the latest valid certificates from our sales team.
What is the minimum order quantity for customized bearings?
MOQ depends on the bearing structure, material, tooling requirements and production quantity. For customized projects, we recommend contacting our team with the drawing or sample so we can confirm the feasible MOQ and production conditions.
How long does it take to develop a customized bearing?
Development time depends on the bearing structure, drawing complexity, tooling requirements, material and testing requirements. Standard bearings can usually move directly to quotation and sample confirmation, while new non-standard bearings require additional engineering and development time.
Can BMT produce bearings according to our drawings or samples?
Yes. Drawings and existing samples are both useful for OEM and non-standard bearing projects. Our team can review the required dimensions and application conditions, confirm the specifications with the customer and then proceed with sample development and production.
