Double Row Tapered Roller Bearings (352000) Tapered roller bearings are mainly used to bear radial load and axial combined radial load, there are double row bearings, bearings and four pairs of double-row bearings. Tapered roller bearing cage generally use stamping cage. double row taper roller bearing metric series bore diameter 352000 160~1400 352200 160~1200 352900 180~1200 352000 180~1200 350600 180~1000 351900 180~1400 351000

Tapered roller bearings and water pump bearings installation should pay attention to the following aspects：1. bearing installation Bearing installation must be dry, clean environment. Should be carefully reviewed before mounting the shaft and housing of the mating surfaces, the shrouds of faces, trench and connection surface machining quality. All surface with the connection, must be carefully cleaned and remove burrs, castings, unprocessed surface must be subject to a net residue sand。
 

We produce various kinds of inch-size taper roller bearings. Below are some models.

Tapered roller bearings are bearings that can take large axial forces as well as being able to sustain large radial forces. The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing. This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical (ball) bearings,

Follow the method of Roller Bearing Mill, in the hollow shaft and the Roller Bearing installation form more unreasonable to use the factory mill operation in the future work to bring some disadvantages. To solve this problem, we offer you the mill the best hollow shaft Roller Bearing assembly installation method.  Industrial use of fine grinding mill with Roller Bearings have been widely in China to promote and save the power consumption,

1, ntn bearing nature of the noise datantn bearing nature of noise is the use of modern processing technology made bearings will occur,NTN Bearing determined the structure of the noise itself.Nature of acoustic noise can be divided into roller, ball impact and jarring sound of three kinds of sound, are as follows:(1) ntn roller bearings roller sound and control noise when running NTN Bearing imports,

ntn bearings in high speed rotation, in particular the speed close to or exceeding the limits of record size of the table speed, the main should pay attention to the following(1) The use of precision bearings;(2) Analysis of the internal bearing clearance (taking into account the bearing temperature rise resulting reduction in the amount of internal clearance);(3) analysis of cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage system.

Tapered Roller Bearings are designed such that cup. Cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Single-row tapred roller bearing is able to carry radial and axial load in one directions simultaneously because an axial component of force is produced when this type of bearingis loaded radially, two bearings are used together facing one another, or two or more bearings are matched and used.
