Introduction

& nbsp; features single or double row needle roller bearing with flange consists of machined outer ring, needle roller and cage components with flange and separable inner ring. X-life needle roller bearing with flange is X-life bearing. these bearings have optimized raceway surfaces. Therefore, it has higher bearing capacity and longer rated life. needle roller bearing without inner ring needle roller bearings without inner ring have extremely compact radial dimensions. However, they require that the raceway of the shaft be hardened and ground. '> 40mm . needle roller bearing with inner ring if the shaft cannot be used as the raceway of rolling bearing, the bearing with inner ring shall be used. this kind of bearing has a single row design, but also a double row design na69 , its d & Ge; 32mm . inner circle displacement the standard inner ring is allowed to have displacement in the axial direction not exceeding the value listed in the dimension table. When large displacement occurs, the standard ferrule can be replaced by wide inner ring IR . inner circle: see page 776 . seal And. On both sides are contact seals. lubrication bearings are lubricated with composite lithium grease ga08 . arcanol load150 suitable for relubrication. For this purpose, the outer ring has a lubricating groove and a lubricating hole. 'EN-US ' > d & le; The 7mm series of NKI have no lubrication holes and grooves. sealing ring and wide inner ring in order to prevent the influence of the outside world, the combination of seal ring series ( G , GR and SD ) and wide inner ring IR can be used for bearing sealing. The sealing ring and inner ring should match the needle bearing. The outer surface of the inner ring can be used as the sliding surface of the sealing lip. sealing ring: see page 804 and tpi128 , single lip and double lip sealing rings. working temperature the operating temperature range of open bearing is & ndash; 20 ℃ to + 120 ℃. limited by grease and sealing materials, the operating temperature range of needle bearing with seal is & ndash; 20 ℃ to + 100 ℃. cage there are two kinds of cages: steel cage and nylon cage. The suffix of the bearing with nylon cage is TV . before using nylon cage bearing, check the compatibility of lubricant and cage material (PA66 GF / h) . suffix see the following table for suffixes of existing designs. suffix of existing design
