In addition, we also make custom, made-to-order ball bearings and roller bearing components that aren't shown on our website or catalog. We have quoted items per print, per sample, and as interchanges for other manufacturer's products.

Q4: What services separate Tianjin DSR Bearing from other suppliers?
A4: Unlike Tianjin DSR Bearing, some bearing suppliers do not manufacture their own products. Many of them purchase bearings in other factory, and quite often, these suppliers will change their source of supply without informing customers, resulting in quality issues. Tianjin DSR Bearing's products are manufactured in north China manufacturing facility.

In addition, we hold a unique spot in the industry because we are able to combine the capabilities of a large bearing manufacturer with the precision and attention to detail of a small bearing shop. This allows us to offer personalized service, short lead times, on-time delivery, trusted bearing expertise, innovative solutions, top quality products, and more.

Q5: Do you have any industry certifications?
A5: Yes. Upon request, we can provide SGS, material certs, inspection reports, and material trace ability. Please include all certifications you require along with your RFQ, if any.

Q6: What is your privacy policy, return policy, and terms & conditions? Is there a warranty?
A6: We do offer a warranty that says all products are free of manufacturing defects, and depending on the circumstances, we may allow returns with a 25% restocking fee.

Q7: What is your manufacturing process?
A7:  All materials are sourced domestically (i.e., chrome steel, stainless steel, ceramic, bronze, brass, etc.). Individual components for the bearings are machined in-house on our CNC lathes. Machined pieces are sent out locally for heat treating (hardening). Upon return, the pieces are precision machined, washed, and assembled into finished bearings. Bearings are laser marked and either stocked or packaged for shipping
