Can the bearings of 7314B/DB be replaced with two sets of 7314BECBP bearings?
The advantage of angular-contact deep groove ball bearings with a 7-series designation and a 40-degree contact angle over ordinary deep groove ball bearings with a 6-series designation is that they can better withstand axial loads; ordinary deep groove ball bearings generally only handle radial loads. In my opinion, if the rotational speed isn’t very high, two regular BCP bearings arranged back-to-back can be used as a substitute
The bearings of 7314B/DB are used in pairs, mounted back to back; they are angular contact ball bearings with a contact angle of 40 degrees, and they serve to position the rotor as well as to bear the axial forces on the rotor. They can be installed and used directly； Two sets of 7314BECBP bearings can replace the 7314B/DB bearings, but they also need to be used in pairs, installed back to back, and the clearance must be adjusted again. In fact, the 7314BECBP bearing can also be installed in a face-to-face configuration, in the same direction, or used individually. However, the methods for adjusting the clearance vary depending on the installation method, but clearance adjustment is necessary; otherwise, it will affect the performance and service life of the bearing.
It can be used; the clearance needs to be adjusted again
Reply 4# *azaia How to adjust the clearance? Can the mechanics make adjustments on-site during installation?
Reply to 2# Dongcheng Xijiu zq: Friend, what is generally used as the standard for determining high or low rotation speeds? Also, my question didn’t mention bearings that start with the number 6!
Upstairs, I know your question didn’t mention deep groove ball bearings with a 6-series designation; I was simply trying to explain the advantages of BECP bearings with a 7-series designation. By speed, I mean at least around 2950, or perhaps around 4400 – after all, our system uses such bearings in the high-speed pump
The axial play of 7-series angular contact ball bearings when used in pairs can be adjusted at the installation site. Adjust it to the required value. This shouldn’t be a problem for a blacksmith.
