- Q: A bearing assembly that can withstand greater torque (other requirements are not required and the axle is cantilevered)
- Suggest landlord or two sets of bearings is better, and two bearings away from the point of good. That is to say, the closer the couplings are from the motor.
- Q: Can I use other types of bearings instead? What's the model instead of the bearing? Thank you
- There is no PN307 modelWith RN307, cylindrical roller bearings, bore 35Then consult me
- Q: CAT can Carter's bearings be replaced by other brands?
- Bearings as standard parts, unless special customized bearings, naturally different brands can replace each other;However, you have not heard of the bearing brand, you can consult the SKFFAGNSK agent to check whether there is a product specification
- Q: The car separation bearing is broken, isn't it? What's the cause of the other broken bearings?
- Judging the quality of the separation of bearings: step down the clutch pedal to half linkage position, and then make a noise, you can judge the separation of bearing damage
- Q: In engineering practice, for needle roller bearings, usually axial positioning is the same as other bearings?
- Needle bearing features are axial can not bear the load, so the operation of the axial direction of the bearing no force, radial installation slightly tight can be, the axial need not limit
- Q: Characteristics of cross roller bearings
- 4, substantial savings in installation spaceThe size of the inner and outer ring cross roller bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.5., high speed capacity6. reduce the shaft length and processing costs, thermal expansion leads to limited changes in geometric size7. 、 adopt nylon separator, low rotating inertia, low starting torque, easy to control angle division8., optimize pre tightening force, stiffness, guide roller running high accuracy9. carburizing steel provides excellent impact resistance and surface abrasion resistance
- Q: What are the world bearing giants?
- International bearing giants:Sweden: SKF (SKF group)Germany: INA/FAG (Schaeffler group)United States: TIMKEN (The Timken Company)Japan: NSK (Nske) NTN (NTN) KOYO (Guang Yang) NACHI (fujikoshi)NMB (Mei Beiya) THK (main line, unit FYH (bearing) main bearings etc.).The Swedish SKF company was founded in 1907, in the rolling bearing sector is the world's leading supplier, experience and professional skills of the bearing and bearing unit, seal, lubrication system, electromechanical integration and service five platform with its more than 100 years, SKF has become a knowledge-based company. In 2007, SKF sold more than SEK 58 billion 500 million.The German Schaeffler Group owns three brands: INA, FAG and LuK, are rolling bearings and linear motion products leading manufacturer, supplier of automotive industry is also well-known engine, gearbox, chassis applications of high precision products and systems. The group represents a high degree of customer focus, exceptional innovation, and highest quality standards. The group has about 74000 employees worldwide, with more than 180 branches in more than 50 countries, with sales of about 10 billion 700 million euros in 2011. This makes the Schaeffler group one of the largest family business groups in Germany and europe.The Timken Company was founded in 1922, operating range: aviation, construction, medical, heavy industry, machine tools, consumer goods, energy and industrial equipment. Wuxi solid Chinese sales agent TIMKENTIMKEN bearing inner ring bearings Co. Ltd., TIMKEN bearing outer ring, roller bearing TIMKEN, TIMKEN bearings, TIMKEN bearings accessories, TIMKEN bearing, TIMKEN metric 3000 series. The The Timken Company set up eight technical centers
- Q: why the inner ring of a knock on the broken, and other small manufacturers desperately not broken, is the material problems or other reasons? The hardness is about the same. LYC62 another 63. How can this be explained? Seek expert advice!
- You may have this bearingImitationThe hardness is not too high,High imitation is the quality of the bad ah!May not be annealed, hard, dryPay attention later
- Q: Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?
- Fork parts with multiple screws, different brands and models, there are differences between the screw size,
- Q: sometimes to the other bearing sliding bearing number, sometimes to the sliding bearing parts inside, why?
- Sliding bearing partsThe bearing is sliding bearing and shaft parts, very smooth, generally made of bronze, anti friction alloy wear-resistant material, in particular, can be made of wood, plastic or rubber.
