Single row cylindrical roller bearings NU20/800EM

Description of the bearing:

1)It is the combination of 2 machined and polished grooved raceways(inner&outer rings), guilding a number of appropriate cylindrical rollers as the rolling elements, with a cage or full complement. This type bearings are designed to carry heavy radial loads at high speed.

2)There are many differernt designs of single row caged cylindrical roller bearings N, NJ, NU, and NUP.

3)The rollers in single row cylindrical roller bearings are always guided between the integral "open" flanges on one of the rings.

4)NJ design bearing has two integral flanges on the outer ring and one integral flange on the inner ring.

5)Cylindrical roller bearings with cage have high radial load carrying capacity, operating at high speed. Full compliment cylindrical roller bearings can accommodate even higher radial loads, but at low and moderate speed

Application:

Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill,vibrating screen and lifting transportation machinery, etc.

Advantages of the bearing:

*  Caged design
*  High radial load capacity
*  Suitable for high speed
*  Enhanced operational reliability

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.
