Pillow Block Bearings company 鈼?Introduction UC bearings with jacking wire outer spherical ball bearing, there are two jacking wires on the bearing, the angle is 120掳, the bearing is fixed on the shaft by the jacking wire during installation, and it is used in an environment with low vibration. Its code name is UC200 series (light series), UC300 series (heavy series). The basic performance of the bearing should be similar to that of the deep groove ball bearing. The outer diameter surface of the outer ring is a spherical surface, which is mainly used to bear the combined radial and axial load mainly based on the radial load. Generally, it is not suitable to bear the axial load alone. The bearing is easy to assemble and disassemble, and can be adjusted. The standard tolerance of the inner ring is a positive deviation, which makes the bearing light when it is matched with the shaft. The UC bearings are widely used, but their installation and positioning are not accurate enough, and the axis alignment between the shaft and the seat hole is poor, and it is mainly used in occasions where the accuracy requirements are not high. Radial insert ball bearings are widely used in textile machinery, ceramic machinery, agriculture, chemical industry, printing and dyeing and other fields. 鈼?Bearing Series The types of the insert bearings include UC200 series, UC300 series, UEL200 series and UEL300 series. 鈼?Production Details 鈼?Factors affecting the turning precision of bearing ring 1. Principle error: It generally occurs in the profile of the ferrule turned by the profiling lathe. 2. Workpiece installation error: It mainly refers to the positioning error caused by the misalignment of the design reference of the bearing ring with the positioning reference during processing and the clamping error caused by the clamping force. 3. Static error of process system: Including machine tool error, fixture error, tool error, which will directly affect the position, shape and size of the bearing ring. 4. Dynamic error of the process system: Including the error caused by force deformation and thermal deformation of the process system, tool wear error, and deformation error caused by the internal stress of the workpiece. 5. Adjustment error: The function of adjustment is to maintain the correct relative position between each surface to be machined on the workpiece and the corresponding turning tool blade. Poor adjustment will cause errors. 6. Measurement error: The error caused by the bearing ring inspection measurement. 鈼?Determine product quality objectives and requirements The quality objectives and requirements of rolling bearings, including the use, structure, and accuracy level of rolling bearings. Due to different uses, structures, and precision levels, the production process is different. For example, the bearing process of P4-level "precision" is different from the 0-level" precision. the process of low-noise bearing is also different from that of ordinary bearings. Determining the quality objectives of the bearing is the key to determining the production process. 鈼?Normalizing of the Bearing Ring Heat the steel to 30~50鈩?above the austenitizing temperature, keep it warm to make the structure completely austenitized, and then air-cool (sometimes supplemented by air blowing, spraying, etc.) to obtain fine flaky pearlite or sorbite structure, the execution process to normalize. The purpose of normalizing is as follows: 1. Adjusting the hardness of steel: Some bearing products require good tempering resistance, that is, after quenching, tempering at 200~250 掳C still has high hardness, and annealing after normalizing can be used to obtain extremely fine pearlite structure . 2. Elimination of reticulated carbides and linear structures: When the steel forging temperature is too high and the cooling is too slow, the carbides precipitate out of reticulated carbides along the austenite grain boundaries. when the final forging temperature of the steel is too low, the grains along the austenite grain boundaries, the deformation direction is elongated and a linear structure appears. This structure cannot be completely eliminated during the annealing process, thereby reducing the impact toughness of the bearing's fatigue strength. 3. Rework of unqualified products of Annealing: Coarse pearlite produced by annealing overheating needs to be normalized and then annealed. 鈼?FAQ (Frequently Asked Questions) Q1: How long will our the inquiry and question be answered?
