1)The angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

2)The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle "α":

 

3)This kind of bearing are available both in open and sealed versions

4) Cage: polyamide cage, sheet steel cage or brass cage .

5) Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads acting in both directions. Radial loads can be supported up to a certain fraction of the axial load. These bearings take up considerably less axial space than double row bearings.

6)The angular contact ball bearing is of separable design  the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.

Advantagess:

*Separable design 

*High combined load capacity 

*Easy to mount and dismount

*Widespread use and versatility

Q1: What does Tianjin DSR Bearing & Manufacturing do? What are your specialties?
A1: With over 15 years' experience, Tianjin DSR Bearing is a manufacturer of a full line of standard ball and roller bearings. Currently, we offer 13 different bearing series which are available across a wide size range, including IDs from 5/64" to 6-1/2″ and ODs from 15/64" to 13-3/4".

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.

Q2: What types and styles of bearings do you make?
A2: We make a variety of bearing types, including ball bearings, roller bearings, thrust bearings, combination bearings, pillow block bearings, custom bearing, and more.

Moreover, we can make bearings in many styles and configurations, including single direction, double direction, caged, banded, separated, open, enclosed, full ball compliment, etc.

Q3: Do you offer any unique secondary services?
A3: Besides bearings, we offer a variety of secondary services to our contract manufacturing customers. Our diverse manufacturing capabilities include CNC turning and machining, manual turning and machining, CNC milling, lapping, super finishing, induction welding, laser marking of finished parts, automatic saw cutting, reverse engineering, and CNC grinding, including ID grinding, OD grinding, cylindrical grinding, centerless grinding, surface grinding, and double disk grinding.

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.
