Full complement cylindrical roller bearings without outer ring are widely used in the gears of planetary reducers. Reducers are important devices required by various machinery and equipment. The bearings are required to meet the requirements of high speed and stability under various working conditions to rotate, and achieve long life. Full complement cylindrical roller bearings without outer ring, directly using the inner hole of the gear for the outer ring and outer raceway of the bearing, to simplify the design of the host and save limited space. In a limited space, the use of The full roller design can obtain the maximum rated load, and the average increase of the effective load should reach about 15% -20%. Buy bearings F-208099 online, click here

Commonly used cylindrical roller bearings without outer ring, including inner ring, the outer ring surface of the inner ring is provided with an annular groove, the groove is covered with cylindrical rollers, and the outer ring surface of the inner ring is located on the roller Retaining rings are also provided on both sides, and circlips are also provided on the outside of the retaining ring. In order to prevent the bearings from falling apart before assembly on the gear, a plastic jacket is needed to temporarily assemble the bearings together, and the plastic jacket is lost when assembled on the gear. The clamping spring is clamped on the groove of the inner hole of the gear, and the retaining ring is used to ensure that the roller does not move axially. However, the cylindrical roller bearing without outer ring of this structure has a complicated structure and is inconvenient to assemble.Buy bearings CPM2527 online,click here 

Full complement cylindrical roller bearings without outer ring are designed to withstand heavy loads. At the same width, this type of bearing has a higher load carrying capacity and a smaller radial cross section than conventional bearings with cages, which can save space, but the speed is relatively low. In order for the bearing to work normally, the bearing needs to bear a small load in the range under continuous operation, that is, C / P<25. Otherwise, wear will be exacerbated due to insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings have a lubrication groove and a lubrication hole on the outer ring. Buy bearings RSL18 3007 online, click here

In addition to being used on the gears of planetary reducers, full complement cylindrical roller bearings are also widely used in large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and cranes. Transportation machinery, etc.
