Ningbo Mosheng Bearing Co.,Ltd. is a manufacturing enterprise which specializes in producing precise miniature and small deep groove ball bearing. Since 1988, there are almost 20 years of producing this ball bearing. And now, our company has the area of 30000 square meters and almost 4000 employees. What's more, our company has the ability of producing 1.8 hundred million sets of bearings yearly.

Production Equipment

One mesh-belt heat treatment production line. According to different usage environment, we adopt different quenching process to improve the bearings' lifespan.

Testing Equipment

Name: Profile roughness tester
Function: Detecting the ring surface roughness and groove curvature profile and so on

Bearing Classification and Selection

For the double row tapered roller bearing, regular manufacturer has their professional designer to design the external packing and produces the external packing through professional factory. So, the external packing should be clear from the line to the color patch.

Common Causes of Bearing Failure

On the one hand, the surface between outer ring and inner ring wear down. On the other hand, when the bearing is under high-intensity work, metals of its surface peel off and then the bearing radial gap increases.

Bearing Lubrication Methods

It's the most primitive way to use oiler to supply lubricant when you find the lubricant is insufficient. This method is difficult to keep the lubricant in a certain number and has the risk of forgetting refueling. So this method is usually for occasion of light load, low speed or intermittent movement. It is better to set the dust cover or ball valve on the filling hole and use the felt, cotton, wool and so on as the filter device.

Roller Bearing Information

Rolling bearing is one precise mechanical component. It can change the sliding friction between operating axle and axle seat into rolling friction, and then reduce the frictional loss. The rolling bearing usually has four parts: inner ring, outer ring, roller and retainer.

Roller Bearing Materials Performance and Requirement

The material of rolling bearing includes material of parts of rolling bearing, retainer, rivet and other auxiliary materials. The parts of rolling bearing is mainly made of steel which usually is high-carbon chromium steel and carburizing steel. With the development of modern science and technology and increase usage amount of bearings, there are higher requirement for bearings. For example, the bearing should have high precision, long usage life, high reliability and so on.

Bearing Steel Smelting Requirement

The rolling bearing's working life and reliability largely depend on the steel's smelting quality. Because of the characteristics of bearing steel, the requirement for steel's smelting quality is stricter than general industrial steel, such as the chemical component, clarity, uniformity.

Mosheng can produce deep groove ball bearing whose inner diameter is equal or less than 45mm and there is no limitation for precision, revolving speed and vibration class and so on. Meanwhile, we can produce bearing with other performance according to the customer's requirement.

Office Supply Equipment Bearings

Office automation equipment includes printer, duplicator and shredder and so on. So on the one hand, the bearing should be high precision and high temperature resistance. On the other hand, there are more thin bearings because of space limitation.

Refrigerator Bearings, Washing Machine Bearing ,Electric Oven Bearings

The bearing should be no noise or abnormal noise when household appliance is working. And it should be long lifespan.

Vehicle Bearings

There are many types of vehicle bearings. The bearing near the engine need to be high temperature resistance and the bearing far from engine needn't. However, all the bearings must have high reliability.

Electric Power Tool Bearings

The bearings used by electric tools should be high precision, high revolving speed and producing less heat and so on.

Fitness Equipment Bearings

There are many types of bearings for fitness equipment. And these bearings should be well sealed and low noise and so on.

Banking Equipment Bearings

The bearing should be no noise or abnormal noise when banking equipment is working. Meanwhile, the bearing should be rustproof and very precise.
