Waxing cylinder roller bearing high-quality free delivery

Company Advantages
1. Each Waxing cylinder roller bearing is originally created and precisely measured by a team of experienced and trained employees– with respect to the wood sizes of the customer's requirements. It achieves both high rotating precision and pretty low vibration level
2. High efficient order operation and stocks of Zhejiang waxing electromechanical co.LTD. assure rapid delivery. The product requires easy maintenance, saving a lot of manual labor
3. The product has become renowned for its energy efficiency. The ammonia-based refrigeration system can achieve great cooling effect while using less power. Thanks to the high-grade steel ball, it stays quiet and smooth during high-speed running
4. The product won't give out an odor. The surface of this product forms a strong hydrophobic shield which prevents the build-up of bacteria and germs. The product has a relatively low frictional resistance and is stable when running
5. The product features high efficiency. The ammonia refrigerant used has a prominent cooling capacity, which is better than other refrigerants. The internal structure of the product compensates for shaft deflections and housing distortions caused by the heavy loads

Cylindrical roller bearing

Cylindrical roller bearings are characterized by high radial-, and moderate thrust-load capacities.  They contain cylindrically-shaped roller, which are nevertheless not true cylinders. Instead, they are crowned or end-relieved to reduce stress concentrations. This particular geometry results in low friction and allows high-speed applications. Cylindrical roller bearings are commonly available in precision grades such as RBEC-5, a classification from the Roller Bearing Engineers Committee (RBEC). RBEC ratings describe the accuracy and tolerance range of different types of bearings. As a rule, the higher the RBEC number, the tighter the bearing tolerances. Typically, cylindrical roller bearings are lubricated with oil, which also serves as a coolant.

Most cylindrical roller bearings are made of alloy or low-carbon steels. Some applications require the use of case-hardened or through-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or through-hardened by conventional heating methods. When low-carbon, carburized grades of steel are used, carbon is introduced after the cylindrical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, fatigue-resistant case and a tough, ductile core.

Bore size and outside diameter (OD) are important specifications to consider when selecting cylindrical roller bearings. The bearing industry uses a standard, numbered system for roller bearings with metric-diameter bores. For bore sizes 04 and up, multiply the bore size by 5 to identify the bore diameter in millimeters (mm). The outside diameter of cylindrical roller bearings includes the housing (if any), but excludes the flange. Other important specifications for cylindrical roller bearings include overall width, rated speed (oil), static axial load, static radial load, dynamic axial load, and dynamic radial load. Static axial load and static radial loads are, respectively, the maximum axial and radial loads that bearings can withstand without permanent deformation. Dynamic axial load and dynamic radial loads are, respectively, the calculated axial and radial loads under which a group of identical bearings with stationary outer rings can endure for a rating life of 1 million revolutions of the inner ring.

Cylindrical roller bearings are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.

Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact. These bearings are suitable for applications that involve heavy radial and impact loading. They are also appropriate for high-speed applications inasmuch as they can be machined very accurately due to their structure. Having a separable inner or outer ring, these bearings can be easily mounted and dismounted.
