The outer ring has thin wall. The drawn cup needle roller bearing has the characteristics of small radial section area, large load carrying capacity, less inertia and economic manufacture. It is suitable for small section height, or when the housing bore isn't used for raceway, this type is recommended to use. The bearing is assembled into the housing bore under a certain pressure without further axial location. The drawn cup needle roller bearing generally takes its shaft diameter as the internal raceway. However, the proper LR type inner ring can be used in accordance with application condition. The drawn cup needle roller bearing has two structures-with retainer and with full of needles. They are divided into openend type and close-end type. The structure with retainer has the single seal ring and double seal ring. The structure with full of needles has a large load carrying capacity. BL can provide all drawn cup needle roller bearings listed in this catalogue, including standard size and non-standard metric size, and inch-series as well as the high-precision drawn cup needle roller bearings with special requirements such oil hole in outer ring, double-row needles, nylon retainer, inner ring, seal ring, etc. (special technical requirement on order). 1

Since the punched outer ring has thin wall and is easy to be deformed in heat treatment, it is unnecessary to inspect the outside diameter of bearing before installation. Only when the inspected bearing is pressed into the standard housing bore, the final size and geographic accuacy can be obtained. The tolerance of housing bore size shall be in conformity with regulations (see Table - 1). The inscribed circle diameter for needle roller will conform to the range of tolerance F8. 推荐的座孔和轴的公差 (Recommended Tolerance of and Housing Bore) 表 1 (Table 1) 轴承座材料 ( 刚性轴承座 ) Material of bearing housing (Rigid Housing) 钢或铸铁 Steel or cast-iron 有色金属或座孔壁厚小于 6mm Nonferrous metal or wall thickness of housing bore less than 6mm 座孔公差 Housing Bore Tolerance N6(N7) 无内圈 With inner ring 轴公差 Tolerance (table - 1) 有内圈 Without inner ring R6(R7) h5(h6) k5(j6) 关于冲压外圈轴承的滚针内接圆直径偏差的正确的测量检查方法 : 1. 测量时应使被测量和标准件处于同一温度, 测量的标准温度为成套轴承滚针组单一最小内径的偏差 min 的检查, 是将轴承压入标准圈中用极限塞规检查 The correct measuring method for tolerance of inscribed circle diameter of needle roller: 1.
