As a Chinese professional logistics drive accessories manufacturer, we offer a wide range of professional logistics conveyor rollers, pipeline transportation composite wheel, forklift chain, roller, such as packaging, printing machinery with shaft roller bearings The company specializes in production of packaging, printing machinery with shaft roller bearings. At present our production of roller bearings, have been exported to USA, UK, Europe and other countries and regions, won the praise of customers. Now our company has developed a large variety Inch roller bearings, packing curve roller bearings, bearing roller bearings, bolt-type roller ball bearing and needle roller bearings. Models are CF4, CF5, CF6, CF8, CF10, CF10-1, CF12, CF16, CF18, CF20, CF20-1, CF24, CF24-1, CF30, CF30-1, CF30-2. Etc.⑵ NN0000K type double row tapered bore cylindrical roller bearings This kind of bearing structure is compact, small deformation under load and therefore suitable for machine tool spindle bearing. Bearing bore is tapered to micro adjust the radial clearance.This kind of bearing outer ring without ribs due, it can be installed separately outer and inner components (with roller and cage), does not limit the axial displacement of shaft or housing, the same size and radial single row cylindrical roller bearings compared to withstand greater radial load.
Cylindrical roller bearings features |
06-17 |
Rolling element is a cylindrical roller bearing to the heart. Cylindrical roller and raceway contact bearings. Load capacity, mainly bear radial load. Rolling ring wall with small friction, suitable for high-speed rotation. According to ring without ribs can be divided into NU, NJ, NUP, N, NF and other single row bearings, and NNU, NN and other double row bearings. The bearing is the inner, outer separable structure. Inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free-end bearings. In the inner and outer side of a double wall, the other side of the ring has a single wall of the cylindrical china bearing company, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy machined cage. But there is a polyamide forming cage.
1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings.
3. N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of the shaft and the housing due to the relative position changes, can be used for supporting the free end.
4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.
5 inner or outer ring detachable, easy installation and removal.
Main purpose:
Medium-sized motors, locomotives, machine tool spindle, internal combustion engines, generators, gas turbines, gear boxes, rolling mill, vibrating screen and lifting and transport machinery.

The provisions of the measurement region
For the measurement of the china roller bearing inner or outer diameter, the southern end plane of the domestic provisions leave the ferrule are each a maximum chamfer coordinate measurements within the region, while the foreign is defined as more or less away from the ferrule ends face each twice chamfered coordinate region measurements.
Size benchmark requirement
Measurement Comparative Measurement bearing dimensional tolerances require the amount of blocks or standard parts as a comparative measurement of the size of the base, where the amount of the block must meet the standard JB/T1078 "provisions of the gauge block, standard parts must comply with the manufacturer competent authorities requirements.
3 when the temperature measurement conditions
Measuring the ambient temperature requirement is 20 ℃, including slim bearing, gauge blocks, standard parts, and the temperature of the measuring instruments must be the same as above them on the same piece of metal plate can be the fastest way to achieve the necessary temperature balance, otherwise take several hours or even days to achieve this balance.
4 allow the measurement error
Can, in principle, allow the measurement error in the tolerance of 10% or less.
5 probe radius and the pressure of the measurement table
In order to reduce the measurement error must be within a possible range, strive to reduce the pressure of the measurement table, - the measuring force and increase the radius of curvature of the measuring head.
In the measurement of the inner and outer diameters of the bearing, the measuring force and the radius of curvature of the probe can be used with reference to the selection.
Compared with the sliding bearing the rolling bearing of the advantages |
01-06 |
1, under normal conditions, the roll bearings efficiency and fluid power lubrication bearing considerable, but compared to the mixed-lubricating bearings to be higher; 2, the radial clearance is relatively small, angular contact bearings available the pretension available preload to eliminate clearance, high running accuracy; Shaft diameter, the same size, the width of the rolling bearing is smaller than plain bearings, the axial structure of the machine can be compact; 4, most of the china roller bearing subject to both radial and axial load bearing composite structures is simple; 5 consumes less lubricant, ease of sealing, easy to maintain; 6, no useful and non-ferrous metals; 7, a high degree of standardization, mass production, low cost.
