Need Assistance Selecting The Proper Custom Bronze Bushings?
There is a growing demand for bronze custom bearings with non-standard specifications. VIIPLUS always works with its customer to find a solution. We can supply plain bearings in a wide variety of materials, sizes, tolerances, and designs.
Bearing Bronze Grades, We offer a broad range of bronze alloy materials beyond our core powdered metal (SAE 841) and cast bronze (CA932 / SAE 660) products. A few of the other bronze alloys offered include high-leaded tin bronze (CA 936 and 937), aluminum bronze (CA 614, 630, and 954), and manganese bronze (CA 863). Solid bronze bearings are made of CuSn7Zn4Pb7 continuously cast bronze. This material is 85% copper and has very good sliding characteristics.
When the demand for multi-custom bearings is put forward, there is a lack of careful analysis, resulting in problems such as poor bearing performance, many failures, and short service life. To avoid similar situations, refer to the following four-step requirement process:
Two basic performance requirements determine the role that bearings play in practical applications. Therefore, the proposal of bearing requirements must include: providing rotational degrees of freedom within the specified range. Provides position control within a specified range (from basic free motion to high-frequency motion or vibration). Determining the actual limits of these requirements is important because bearing life is a statistical prediction within these limits.
Many application parameters determine product performance. Although only a few parameters may be important in a particular application, careful analysis of all parameters is necessary to ensure that no important parameters are missed. Performance application parameters can be divided into the following 4 categories: 1. Physical parameters. Including the available space of the bearing or bearing system, The bearing or bearing system can bear the load, the shape, material, dimension, and tolerance control of the shaft and housing is integrated into the bearing to simplify the installation structure 2. The higher the working temperature, the greater the available space and the bearing load of the bearing system, and the higher the precision and reliability. However, the cost of adding additional bearing loads is high, so there is no need to add them unless necessary. The design of the shaft and housing has a large impact on the final bearing performance. The shaft should be a solid cylinder and the material used should be fully compatible with the thermal expansion coefficient of the bearing. The cross-section of the housing should be uniform to provide full circumferential support for the bearing. To ensure precise alignment, the shaft and housing should also feature precision machined shoulders or races. 3. Operating parameters. include: 3.1 Speed determines the number of load cycles that the bearing can withstand, and thus affects the service life of the bearing. Speed is usually expressed in terms of the relevant guide parameter “dN”, which also affects other aspects of bearing operation, including oil flow profile, oil film thickness, centrifugal load on rolling elements, displacement, overheating, and lubrication method. 3.2 Load can be decomposed into three directions radial, axial, and bending moment and the loads in these three directions will correspondingly generate constant load, alternating load, vibration load, or shock load. The combined effects of these loads should be carefully considered to ensure maximum bearing life and optimum performance. 3.3. Environmental parameters, the environment is a fixed factor for the final product, but whether the bearing is to be protected or exposed to a certain environment is an optional design factor. Either ambient temperature or internally generated temperature should be considered as the main consideration. The nature of the surrounding medium (liquid or gas) may place certain requirements on tightness, special anti-corrosion treatments, or relubrication. In addition, any special environment (such as a magnetic field or radiation environment) is also a necessary factor that should be considered in the design. 3.4. In Economic parameters, the total system cost should be carefully weighed, not only the bearing cost but also the total cost of bearing installation and replacement should be considered. Many parameters are fixed in a specific application, but some are variable and can be modified or controlled if necessary. The designer makes the final choice after weighing these parameters.
If the performance is so significantly reduced that the bearing no longer meets the original requirements, the design life of the bearing in a particular application will be reduced. There are 15 common injury modes: foreign object wear Etching Assistant Insufficient lubrication Fatigue peeling Transitional preload or overload The shaft end clearance is too large Inaccurate and misaligned seat washer and shoulder Damage during transportation and installation Damage to bearing cage or fixings Raised locations and damage during assembly Improper mounting of housing or shaft Brinell indentation damage and impact damage False Brinell indentation electrical burn to calculate the service life. Other factors are empirical factors related to a particular application, such as temperature, lubrication, overloa,ding or contamination, which may reduce service life.
The above factors must be carefully considered before selecting a specific bearing. For more demanding application fields, specific design schemes or control methods can be formulated according to the following contents: Lubrication type, method, cycle Use of dust caps or seals Cage configuration, material, and clearance Basic tolerances and corrections Radial clearance or contact angle preload material change Geometry Correction for Contact Areas Special balls or ball accessories Complete special design
