08 Nov 2018 By 3034377278
Schaeffler Group ran “efficiency drive, Mercedes-Benz in the future” under (Mobility for tomorrow) strategic vision, Schaeffler develops less conflict, more power and better cost vehicle bearing commodities and future-oriented electromechanical integration solutions. In the 2015 Shanghai Auto Show, exhibited FAG Schaeffler protection Free truck hub bearing unit, the international trade multiple continents through 10 years of production use, to be completed more than one million kilometers of life. By roller, roller and seals optimized planning, effectively reduce conflict, to be completed by 1 million km fuel savings of 3,000 liters, and now a brand 6 × 2 van proven. By decrease contact stress, optimizing internal planning, increase FAG dynamic bearing load, low conflict Commercial Axle FAG Bearings main Save comparable existing products more than 40% reduction in conflict, effectively reduce costs.

Schaeffler believes decrease conflict and optimize the cost not only for truck operators beneficial, and help decrease carbon dioxide emissions of the whole society, to make contributions to eliminate the haze and improve the environment. Schaeffler wheel bearing plan fully using a lightweight planning in order to protect the truck free FAG wheel bearing unit as an example, can make 6×4 tractor weight 65 kg or more, 8-12 meters passenger weight 40 kg or more, effectively reduce emissions, improve fuel economy.
Schaeffler Greater China Car Division President Yang Hanbing say, ten years, Schaeffler has established cooperation with our supplier and FAW, China’s heavy truck, Shaanxi Auto and other domestic commercial vehicle spring primary commercial enterprises relationship. Schaeffler Nanjing production base of truck wheel bearing production line put into the program this year, annual production up to 500,000 sets. Facing commodity upgrading and export needs, Schaeffler determination for domestic truck manufacturers to bring the most advanced, most reliable and most suitable goods, solutions, technical support and after-sales service, and win-win.

KOYO Bearing Analysis of Trajectory and Operating Methods

08 Nov 2018 By 3034377278
When KOYO bearing rotation when the raceway surface of the bearing inner and outer rings and rolling body is due to rolling contact, so run track for the dark side, running track attached to the roller surface are not unusual, thus becomes available known load conditions, so when disassembly KOYO bearings, please pay attention and observe strict raceway running track.

If you look at the trajectory, then this will only burden that radial load to bear large axial load, moment load to bear, or in the extreme rigidity of the bearing housing inequality. You can check whether the bearing loads and added an unexpected installation error is big enough, etc., and become investigated for clues to the cause bearing damage.
Contact seals are seal parts relative to its moving parts there is no gap seal. This seal due to direct contact seal with a mating member, it is generally only suitable for medium and low speed operating conditions. Friction in the work of a large, heat is also large, the contact surface is easy to wear, resulting in performance degradation and sealing effect. Contact seal commonly used form of blankets seals, cup seals and other structure.
According to the bearing operating conditions and the working environment of the sealed bearing KOYO degree requirements in the design of the seal is often the comprehensive use of various forms, in order to achieve a better seal.
Generally from the use of perspective to note the following:
1, KOYO bearing clearance should be appropriate, too large an impact, too small to poor lubrication, may bush-burning.
2, KOYO bearing and journal surface quality and geometry should be strictly guaranteed.
3, to improve the quality of lubrication, control oil pressure, temperature and flow, strengthen the oil filter.
4, the control of the diesel engine temperature condition in the case of cold hot work are unfavorable. Cold weather, diesel engine starter should be preceded by warm-up, and the hand crank to make the oil into the friction surface.
5, using compliant fuel and lubricants.

How to Maintain NSK Bearings

08 Nov 2018 By 3034377278
NSK Bearings kept clean and lubricated and pre-examination of NSK bearings, NSK Bearings shall first clean the surface and remove NSK Bearings surrounding parts. Here we must note, seal is very fragile parts, so the inspection and dismantling NSK Bearings Do not use excessive force to avoid damage to the parts. If the poor have shown symptoms when checking NSK bearing seal and the surrounding parts, be sure to replace the lost, poor seal will avoid causing damage to NSK Bearings.

Methods for Determining Whether SKF Bearings Can be Reused

08 Nov 2018 By 3034377278
SKF bearings are imported bearings, precision parts, SKF bearings for machinery service, preventive maintenance tools, condition monitoring and maintenance of a series of decision support system to achieve the optimal plant asset efficiency and maintenance. Therefore, SKF Bearings For some industries, has played a crucial role.
However, if the following occurs SKF bearings spoken defects can no longer be used and should be replaced immediately new SKF bearings. details as follows:
(1) SKF bearing inner race, outer race, rolling, keeping any cracks or notches on a shelf;
(2) SKF bearing rings, rolling element fault on any one;
(3) SKF bearing raceway, a significant injury on card wall, rolling;
(4) SKF bearing retainer significant wear or rivet significant relaxation;
(5) SKF bearing raceway, rust on the rolling body injury;
(6) SKF bearing raceway, there are severe dents and hit the marks on the rolling elements;
(7) the inner diameter of the inner surface or the outer diameter surface of SKF bearings has significant creep;
(8) due to heat the discoloration significantly.
So, when SKF Bearing the above situation, please do not continue to use, should be replaced immediately new SKF bearings. Avoiding unnecessary accidents.

NTN Bearings Application

08 Nov 2018 By 3034377278
NTN bearings are most representative of the rolling bearing, widely used. For high speed or high speed operation, and very durable, without regular maintenance. And the class NTN bearing friction coefficient is small, extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision.
Size range and diverse forms, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of NTN bearings. The main radial load, also can withstand a certain amount of axial load.
Select a larger axial clearance radial load carrying capacity increase, when the contact angle of pure radial force is zero. When the axial force, the contact angle is greater than zero. Commonly used stamping Ribbon Cage, machined solid cage, sometimes with nylon frame.
NTN bearings installed in the shaft, the axial clearance in the range of NTN bearings, shaft or housing to limit the two directions of the axial displacement, it can be positioned in the bi-axial direction. In addition, the class also have some bearing NTN-aligning capability, when compared to shell hole tilt 2 ‘to 10’, still work, but has some influence on NTN bearing life. NTN bearing cage mostly steel stamping Ribbon Cage, a large multi-use vehicle NTN bearing metal solid cage.
NTN Bearing commonly used in transmission, instrumentation, motors, appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery.
