【 Jiaxing bearing factory. The question of bearing internal clearance

Jiaxing bearing group sales co. , LTD is bearing factory in jiaxing at the center of the province set up a spot directly, inventory sufficient, specializing in HRB bearing brand, service users, professional engineer to solve technical problems for the user, today to introduce the issue of bearing internal clearance. Bearing internal clearance is defined as one of the bearing ring relative to the other bearing ring in the radial direction ( Radial clearance) Axial (or The axial clearance) Removable total distance. For bearing clearance, must distinguish the clearance before installation, and after installation and achieve its working temperature of clearance ( Work clearance) 。 The initial bearing clearance ( Before the installation) Is generally larger than the working clearance, due to different interference quantity tolerance matching, and bearing ring and adjacent parts of different degree of thermal expansion, leading to ring expansion or compression. To make the bearing running, radial clearance is very important. General guidelines, ball bearing work clearance should be zero, or slightly preloaded. But for cylindrical roller, spherical roller, in the operation must have certain residual clearance. Tapered roller bearing is the same, but in need of high rigid bearing configuration, such as gear bearing configuration, tapered roller bearing at a certain amount of preloaded to install. When bearing configuration USES is the suggested tolerance matching, and under normal working conditions, choose plain bearing group games, you can get a suitable job clearance. But when the installation conditions and general terms and conditions of the difference, such as bearing of two ring is interference fit, or bearing ring temperature difference is very big, should choose bearing clearance than normal group of bearing large or small. In this case, it is recommended that check the residual clearance after installation. Here, we are told by ordinary group of clearance of the bearing, general with suffix C1 to C5 to represent: suffix internal clearance C1 is less than the C2 C2 less than ordinary CN ordinary group clearance C3 is greater than the normal group of C4 is greater than the C3 C5 is greater than the C4 among all kinds of bearings, different kinds of bearing clearance ( Radial clearance, axial clearance) Is different, can refer to related information in the installation.
