Q:Does deep groove ball bearings belong to thrust bearings?: No, please. - Allen bearings

Q:How are the parts assembled together for deep groove ball bearings?: Deep groove ball bearings are composed of inner ring, outer ring, steel ball, upper and lower cage.Assembly sequence: the outer ring shall be fitted with inner ring, the cage, the steel ball, the other cage, and finally the rivet (hole on the cage).

Q:The deep groove ball bearing rubber ring is too thick. What's wrong with it?: Large frictional resistance

Q:Deep groove ball bearings and so on, these bearings inside and outside the ring surface is generally metal color, or surface chrome plated?: Who recommended what answer, give an irrelevant answer.

Q:Why is the rated speed of deep groove ball bearings (reference speed) greater than the limit speed, greater than almost double?. Only deep groove ball bearings are like this? Why?: Reference speed (with respect to heat) and limit speed (as opposed to physical structure) are parameters that vary according to consideration. Because the contact surface of the deep groove ball bearing is the smallest, and the friction force is the smallest, so the reference speed will be higher than the limit speed.

Q:Bearing capacity of axial and radial forces of deep groove ball bearings and angular contact bearings: Deep groove ball bearings are mainly subjected to radial forces and are not subject to axial forces. Angular contact ball bearings can bear radial force and one-way axial force.Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient (friction, coefficient) during movement, and guarantee its rotary accuracy (accuracy).According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts, namely, outer ring, inner ring, roller and cage. Strictly speaking, the rolling bearings are composed of six big parts, namely, outer ring, inner ring, rolling body, cage, seal and lubricating oil. Mainly with the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.

Q:What are the differences between deep groove ball bearings 16004 and 6004??? 1 is that a separate row? What about 6004?: Are deep groove ball bearings, single row, no seal, their static load is different, there is a slight difference in weight.

Q:What is what is the deep groove ball bearings, self-aligning ball bearings, spherical roller bearing is what: The 0 category is the deep groove ball bearing type.1 self-aligning ball bearing self-aligning roller bearing.3 class is the hope can help you

Q:What's the difference between HRB's deep groove ball suffix 2Z and 2RZ?: Pro, it is said that 2Z is double sided iron cover, dustproof role; 2RZ is double glue cover, dustproof and waterproof function, according to their own needs to choose oh. This is my first two days ago from Kazakhstan axis Shandong spot center when buying the bearings learned, and I hope to help you!

Q:Deep groove ball bearings on the outer ring processing two grooves, and then add two aprons play what role?: I can't make myself understood.The inner recesses of the outer race must be ball oriented.The outer ring is mainly used to cooperate with the external ring, when the General Assembly Design of the bearing outer ring is designed with shaft, theoretically will use the assembly slightly interference, so when the general assembly must heat the bearing seat, with hot charging way to smooth assembly.But the hot charge will be very troublesome, so in production, is not very strict for the general requirements of the bearing assembly, can be matched with a transition, but in order to ensure the bearing outer ring can not rotate in the bearing seat, give him added two ring for fixing.The groove was designed for rubber rings.
