ntn bearing lubrication methods introduced 41, oil ring lubrication: lubrication only way for the horizontal axis. By hanging in the shaft and can rotate the ring to the oil pool oil into the bearing. Applicable to medium-speed shaft diameter greater than 50mm and high-speed bearings. Oil ring preferably seamless, bearing wide-diameter ratio less than 2, may use only one oil ring, Otherwise required two oil ring.

1: ntn bearing performance:1.ntn bearing stiffnessntn bearing stiffness, is ntn bearing power generating units, the size of the required deformation. Rolling of elastic deformation is small, in most machines do not have to be considered, but in some machines, such as machine tool spindle,the bearing stiffness is an important factor, the general should be used cylindrical and tapered roller bearings. Because these two types of bearings and loaded

ntn bearing clearance adjustment. Radial bearing clearance with top clearance, side clearance, shown in Figure 1. Tip clearance can be kept liquid friction, the numerical size of shaft, rpm, the viscosity of the oil. Generally between control I/lO00d ~ 3/lOOOd (d axis diameter). Backlash is the role of the accumulation and cooling lubricants, the formation of the oil wedge,

ntn bearing kit and the outer ring of the processing methodsntn ball bearings machining process: ntn ball bearing raw materials processed by the state of the same vary, cut or ball of light which fell before the process can be divided into the following three, before heat treatment processes, but also divided into the following two kinds,the whole process are: bar or wire stamping (stamping bar after some red zone and annealing needed) - fell cut, coarse grinding,

Roller bearing frequent minor injuries, such as inventory, the creation of small water rust, and transport processes of small micro-abrasion, repair easy and wasteful to discard such cases. In addition to economy outside the repair bearings are the technical, requiring mender fully understand the technical requirements of the corresponding bearings,and bearings and parts thereof in structure, process and material characteristics on the otherwise difficult to ensure that repairs are bearing meet the required results
