Full complement cylindrical roller bearings to withstand heavy loads and design. In the same breadth, the bearings and traditional bearings with cage, compared with a high load carrying capacity, small radial section, you can save space, but the speed is relatively low. To make bearing work, in the case of continuous operation, the bearings must bear a certain minimum load, ie, C / P <25. Otherwise it will aggravate frayed due to insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings in the outer ring has a lubrication groove and lubrication holes.
