30304 bearings mainly bear the foot-path relying mainly on radial, axial union load. The bearing bearing capacity depends on the rolling in an angling of the outer lane, the greater the angle is, the greater the bearing capacity is. This kind of bearing belongs to the separating bearing, according to rolling in the bearinghttp://c.zcwz.com/show.asp? id =The row of 197 body counts and is divided into the uniline, a pair of listing and four tapers to roll a sub bearing. Uniline’s taper rolls the backlash of the sub bearing needs users to adjust during installation; Pair was listed and backlash of the sub bearing of rolling of four tapers has already been given defi nitely according to user’s requirement when the products are dispatched from the factory, user need adjust not.
30304 taper roll sub bearing have conical inner circle with outer lane get away dish, the taper rolls the son arranges between the two. All the intersection of taper and the intersection of projection and line of surface meet with any in the intersection of bearing and axis. The design make taper roll sub bearing very much suit bearing compounding ‘ Radial and axial) Load. The axial load ability of the bearing is determined by the fact that exposed to the angle ? ? mostly; The bigger angle of ? ? is, the higher axial load ability is. The angle size is by calculating the coefficient e expresses; The larger e value is, it is the bigger to exposed to the angle, the greater the applicability that the bearing bears axial load is.
The sub bearing is usually separating type that the taper rolls, is carried and rolled the something small and hard and keeps the taper inner circle assembly of inner circle composition of a assembly being all right with the outer lane of the taper (outer lane) Install separately.
30304 tapers roll the sub bearing is used in trades such as the car, rolling mill, mine, metallurgy, plastic machinery,etc. extensively.
Warm suggestion: Because marque kind numerous, picture can’t one first uploading, some products can’t be put on the shelf one by one either, hope to understand, the product of this shop is complete, the whole kind, such as finding the type needed in this shop, please contact shopkeeper!
