Product Description

Details of Cylindrical Roller Bearing

Cylindrical roller bearings, generally separable bearings, are usually guided by two retaining edges of a bearing ring and consists of cage, roller and guiding ring. This bearing is convenient to be installed and dismantled, especially when the inner and outer ring as well as roller and shell have coordination. This bearing is generally used to withstand radial loads, and only when the inner and outer ring are with the edge of the single row bearings, it can withstand smaller axial loads or larger intermittent axial loads. Compared with the deep groove ball bearings with the same external dimensions, it has larger radial load capacity; from the structural point of view, it also fits high speed rotation.
Cylindrical roller bearings are mainly used in machine tools, petroleum, vibrating screen, rolling mill handling machinery and various industrial machinery.
Cylindrical roller bearings are designed with cambered rollers and raceways so as to eliminate edge stress and improve bearing life.
Cylindrical roller bearings have a certain angle of inclination for the retaining edge, so its axial load is larger than the conventional design. 

NJ: Its outer ring is double retaining edge and inner ring is single retaining edge.
NF: Its outer ring is single retaining edge and inner ring is double retaining edge.
NJ and NF can limit the shaft or shell of a direction of the axial displacement, realize one-way axial positioning, and can withstand a small one-way axial load.
NUP: Its outer ring is double retaining edge. Inner ring has a retaining edge on one side; the other side has a retaining ring. This bearing can make two-way axial positioning of the shaft and can withstand two-way axial force. The structure of the bearings can be NUP-N. NJ with tilted retaining ring HJ can be used as a locating bearing just like NUP.

Playground Equipment

Slewing bearing can provide excellent performance experience and safety guarantee for amusement equipment, and the durability of slewing bearing is also the main concern of technical engineers. For more than 20 years, slewing bearing solutions have been used in many key applications of large amusement equipment. reflect.

We designed the cross-sectional area to remain the same as the raceway center distance increased, and the slewing ring achieves better dynamic capabilities with less mass.

Key advantages include:
* Lighter weight
* Save spaighter weightce
* Long life and lower maintenance costs
* Better stiffness
* Better lubrication in extreme conditions

 

Medical Device
With the comprehensive development of scientific and technological strength, the social economyu has been improved faster, and the medical equipment has also been comprehensively improved.

 

Mining & construction machinery

Mining machinery and heavy construction machinery industry uses a range of different types of highly specialized mobile machinery. . The places where mining machinery and construction machinery are active are mostly mining sites such as mountains and deserts that are far away from ordinary human life. These heavy machinery work in the harshest environments and require continuous low-friction work without reducing load capacity and minimum. assembly and adjustment time. Solving the bearing heating problem caused by the large exciting force, high vibration frequency and continuous operation of vibratory rollers for users has become the focus of the work. Mineral crushing machinery, cutting machinery, screening machinery, loading machinery, conveying machinery and other equipment in the use environment of bearings, users desire products with robustness, durability and high reliability to resist these harsh working conditions.

Transportation vehicle

Metric and inch needle roller bearings have various structural types, mainly including open drawn cup needle roller bearings, closed drawn cup needle roller bearings, needle roller bearings with inner ring and needle roller bearings without inner ring/without inner ring Cage needle roller bearings, caged and cageless needle roller bearings. Widely used in automobiles, motorcycles, mopeds, power tools, textiles, agricultural machinery, printing machinery, construction machinery, automatic instruments and other fields.

Automatic machinery

Industrial robot bearings mainly include two categories: one is thin-walled bearings, and the other is crossed cylindrical roller bearings. In addition, there are harmonic reducer bearings, linear roller bearings, spherical plain bearings, etc. Bearings with good performance have large bearing capacity, good rigidity, high rotation precision and easy installation.

Q4:  How to customize bearing(non-standard) from your company?
A:  We offer OEM,Customized(Non-standard) service and you need to provide drawing and detailed Technical Data.
Q5:  What should I care before installation?
A:  Normally, the preservative with which new bearings are coated before leaving the factory does not need to be removed; it is only necessary to wipe off the outside cylin­drical surface and bore, if the grease is not compatible with the preservative, it is necessary to wash and carefully dry the bearing.Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.
Q6:  How to stock and maintenance my bearings right? 
A: Do not store bearings directly on concrete floors, where water can condense and collect on the bearing;Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity or sudden and severe temperature changes that may result in condensation forming;Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
