R series of ball bearing for air-conditioning

Q:How can we split the deep groove ball bearings?: The steel cage can be disassembled first.

Q:6207, deep groove ball bearings can withstand the axial force of how much?: Under this kind of force condition, it is better to use the opposite angle contact. The deep groove ball is mainly radial, and the axial direction is not the main direction of force. Plus this size and speed, the 7207 is the best fit

Q:Are deep groove ball bearings rolling bearings?: As the name suggests, rolling bearings

Q:6010 is the ball bearing deep groove ball bearing?: It is deep groove ball bearing. Its inner diameter is 50mm. It can be imported

Q:Deep groove ball bearings 61805, 16005, 61905, 6005, these 4 bearings bore 25, how many are four figures, and some five figures?: The standard code for bearings is 6 - 61805, for example, 6 for deep groove ball bearings, 18 for outer diameter and width size series, and 05 for internal size series. The code for the zero series can be omitted, so my bearing code is 4 bits and 5 bits. Specific bearing coding and naming rules

Q:Deep groove ball bearings and so on, these bearings inside and outside the ring surface is generally metal color, or surface chrome plated?: Outer cover milling installation opening: inner ball into 90 degrees, into the outer garment deep groove ball bearings: the steel ball into the inner coat - release ball bearings, first remove the cage, the ball "catch" to one side, the inner and outer ring from the.

Q:Deep groove ball bearings how to make, how to put in the steel ball?: Deep groove ball bearings are mainly divided into inner and outer rings, steel ball, cage, sealing ring (dust cover).

Q:I want the standard is best GB, and if other mechanical standards are also ok. 2, mainly to bearing diameter tolerance (preferably all grades have).: Go online to search. You should be able to find what you need

Q:What's the model for deep groove ball bearings with an inner diameter of 20 and an outer diameter of 50?: Standard product, without this size.1., according to your size, that is non-standard, or a manufacturer for customers custom-made size (belongs to non-standard)2. size error, the outer diameter may be 52, and if it is 52mm, then the model is 6304 (the old code 304)

Q:See a lot of deep groove ball bearings, inner circle interference fit, the outer ring and hole clearance gap, the gap is roughly 0.04mm, what's the advantage of this cooperation? The hole is aluminum and the shaft is made of steel. If there is a gap, what is the meaning of the bearing accuracy?: The bearing clearance is negligible and almost negligible, which is where the accuracy is. Another point of view, if there is no gap bearing operation does not burn?
