DSR bearing PVC Sheet Calender Machine 7207 B angular contact ball bearing open nylon cage one row of balls high radial loads and axial loads in one direction
Angular Contact Ball Bearings 7200 and 7300 Series
The angular contact light 7200 Series and 7300 medium Series is dimensionally interchangeable with the radial 6200 and 6300 series.
A single bearing is recommended for applications in which the trust load is in one direction or, in case of combined loads, the thrust load is high in relation to the radial load. A duplex pair is recommended for applications where trust is present in both directions or where axial displacement of the shaft must be restricted. For exceptionally high thrust loads in one direction, tandem pair can be utilized opposed by a third bearing.
Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing. Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. If you don't see your sizes please contact us.

Features
- angular ball bearing with one row of balls
- suitable for high radial loads and axial loads in one direction
- it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
- suitable for high running accuracy, quiet running and high speeds
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- good fixed bearing property in the X- or O-arrangement in pairs

Packing
Application
PVC Sheet Calender Machine
Calenders are machines which are used for the manufacture of rubber webs and rubber sheets as well as for coating and friction
fabric or steel cord.
High requirements are made on the quality of the bearing, since the latter determine the quality of the product to a large extent.
There are the following advantages of the our bearing over the friction bearing:
1 while the journal diameter is almost the same, there is a lower distance from the bearing centre to the roll body edge and therefore a lower roll deflection.
2 no running-in period in case of commissioning new bearings or after any roll change.
3 reduction of the drive power by approximately 25 percent
4 less stress put on the lubricants
Our goal is to make your work safer and more efficient.

Frequently Asked Questions
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.
