SRG is the authorized distributor of Koyo bearings for various countries in the Middle East and North Africa. It is based in Beirut, Lebanon.The partners have a long history of over 50 years in the field of automotive and industrial spare parts, and particularly in bearings.
However severe the application, whatever the environment your product is required to operate in, ENSO has the expertise and ability to specify the appropriate bearings.
It would occur when part of our bearing damaged. Because of wrong operation or error installation, some part of KOYO bearings raceway and rolling body be damaged, when bearing rolling over the damaged bearing component in operation, it will produce a particular vibration frequency. By analysis the vibration frequency ,we can identify the damaged bearing parts.
If Japan KOYO bearing appear deformation it may occur excitation. When bearing ring matched closely with bearing seat or drive shaft, the bearing ring would appear deformation for it need adjust it's shape to match the components shape . If deformatied, vibration may happen in the operation. Therefore,machined the KOYO bearing seat and the drive shaft to the required tolerances are very important.
In addition, vibration behavior will also happen in the application. In many applications, the stiffness of the bearing is same with the surrounding structures'. Because of this feature, as long as the correct choice of bearings ( including the preload and clearance ) and its configuration in application,it may reduce the the vibration in working.
And the vibration produced when quantity of loaded rolling changed. When a radial load on one import bearings, the rolling body's number of the bearing loadcarrying slightly changed in the running, that is: the excursion of the direction of load shift. So the resulted vibration is unavoidable, but can alleviate through the axial preloading, it can load in all the rolling body (except cylindrical roller bearings).
JTEKT Corporation engineering and manufacturing capabilities range from super large bearings with outer diameters of seven meters to miniature bearings with inner diameters as small as one millimeter. Utilizing new materials and the latest in manufacturing technology,JTEKT Corporation has developed hybrid ceramic bearings and a variety of extreme special environment bearings to meet the increasingly severe and demanding requirements of modern industries. JTEKT Corporation stands at the forefront, as a technological leader in the U. S. and World Bearing Industry.
Koyo has become the worlds third largest producer of bearings with 16 manufacturing sites and 53 offices in 18 countries. Their 1996 worldwide sales exceeded ?¨o1,630 million and much of this revenue is derived from their strength in the automotive field. Their primary product strengths include ball and taper roller bearings, needle roller bearings, water pump spindle bearings, clutch release bearings, miniature bearings and hub units with ABS sensors.
After careful consideration, Koyo has decided to change many common sizes of spherical ball bearings, from bronze to a steel retainer. The advantages to making this change includes increased load capacity and improved availability.
Bearings play a key role in the operation of virtually all types of machines. As an integrated bearings maker, Koyo designs and manufactures all types, from miniature bearings one millimeter in diameter to bearings over seven meters in diameter
