MANUFACTURING
4 links: Forging link , Heat treatment, Grinding processing, Assembly.
1. Forging link
The forging link is an important link to ensure the reliability and life of the bearing. After the raw materials are forged, the blank of the bearing ring is formed. At the same time, the organizational structure of the raw material becomes denser and the flow linearity becomes better, which can improve the reliability and service life of the bearing. In addition, the quality of the forging process will directly affect the utilization rate of raw materials, thus affecting the production cost.
2. Heat treatment link
The heat treatment link is the high temperature treatment of the bearing ring after forging and machining, which directly affects the uniformity of carburizing in bearing rings, can improve the wear resistance and hardness of the bearing, and is also an important link affecting the reliability and life of the bearing.
3. Grinding processing link
After heat treatment, the bearing ring also needs to be grinding, which is an important link to ensure the bearing accuracy. After grinding, the production process of bearing rings is basically completed.
Bearing inner and outer ring process flow:
bar -- forging -- turning -- heat treatment -- grinding -- super-finishing -- parts final inspection -- rust prevention storage
The main production equipment includes: Cold rolling machine, automatic ball bearing internal grinding machine, quenching line, annealing furnace, press, CNC lathe, bearing grinding machine, internal groove grinding machine, external groove grinding machine, high precision horizontal axis table surface grinding machine, CNC milling machine, center less grinding machine, high precision through grinding center less grinding machine, precision channel super lapping machine, internal surface CNC grinding machine, CNC reciprocating double end grinding machine, high temperature and high speed bearing testing machine, heat treatment Production line and quality testing equipment.
4. Assembly process
Rolling bearing parts such as inner ring, outer ring, rolling body and cage, etc., after passing the inspection, enter the assembly workshop for assembly, the process is as follows: Part demagnetization, cleaning → Inner and outer rolling < groove > size group selection → Closing sleeve → check clearance → riveting cage → Final inspection → Demagnetization, cleaning → Rust prevention, packaging → into finished product warehouse (packing, shipping ).
FAQ
Load levels seem to vary from manufacturer to manufacturer, is there a single method you can use to compare similar styles of bearings?
Load ratings do not vary from manufacturer to manufacturer, and the methods used to calculate load ratings vary. Some manufacturers use the ABMA standard, some use the US industry standard, and some use the equivalent dynamic load calculation. In general, if the interior design is the same, the load rating will be equal.
What factors should be considered when choosing agricultural machinery bearings?
All application data (load, speed, direction, etc.), intended use, and environment.
What does "motor quality" mean?
The term "motor quality" is often used to describe bearings of higher quality than standard ABEC-1 bearings.
SEALING TYPE OVERVIEW
JB BEARINGS Sealing System
Bearing as one of the most important parts of modern agricultural machinery, its working status is often related to the normal operation of the equipment, and agricultural bearings due to the diversity of the use of the environment, the non-standard product structure, the general sealing method can not be accurately applied. For example, the impact and mud of the ground preparation machinery, the low torque rotation of the planter, and the appropriate sealing method need to be selected for different working occasions, which requires the bearing manufacturer to have a perfect sealing system to ensure the normal operation of the machinery.
More and more farmers are realizing the benefits of using tillers with independent cutters, faster speeds and better soil mixing capabilities, which directly saves more costs for the farm and provides better seedbeds for crop production. As the core farming component, the agricultural hub unit must have strong anti-bias load impact ability and have perfect sealing performance, and in order to ensure work efficiency, it must reduce maintenance time and easy installation and replacement, and have lower energy consumption to reduce costs.
Seal Failure - the Biggest Challenge
According to our long-term experience, about 78% of agricultural bearings and agricultural hub unit failures are due to the failure of the seal system, and the reasons for seal failure are various, so our recommendation is that the development of the seal system needs to fully understand the actual operating conditions, and then optimize through a systematic plan, rather than relying on a single seal. At the same time, the structure of the mating parts is optimized, only in this way can reliable product performance be guaranteed.
A complete sealing system, from garden mower machinery to municipal sweeping machinery, from soil tillage to seedbed formation, from precision sowing to crop harvest, JB BEARINGS sealing system always ensures the stable operation of your equipment, reduces the cost of maintenance and maintenance, and improves fuel economy.
For a long time, JB BEARINGS provide reliable performance products for agricultural machinery. One of the reasons is our continuous exploration and research on product sealing. The process is long-term, and requires a lot of investment in human and material resources. But we always believe that these efforts will eventually be paid off. For our customers to bring more benefits, greatly improve the work efficiency. For the agricultural machinery industry contributed to our modest efforts.
