◎The outer ring of drawn cup needle roller bearing is punched with the high-qualty steel sheet The outer ring has thin wall.The drawn cup needle oller bearing has the characteristics of small radial section area, large load carrying capacity. less inertia and economic manufacture. I is sutable tor small section height, or when the housing bore isnt 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 oller bearing generally takes its shat diameter as the intemnal raceway. However, the proper LA 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 dvided 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.
◎CWN can provide all drawn cup needile 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 oller 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).
◎The outer ring of drawn cup needle rolle bearing is punched with the steel sheet. It has the small sectional height and the large load carying capacity and is suitable for economic mass production.
◎The interference fit between outer ring and bearing housing is applied to this kind of needle roller bearing without axial fixing device. Even for the condition of high load, it fully maintains bearing function either. In addition, with the large greasestorage capacity, it is unnecessary to add grease for a long-term operation.
◎Since one end of the close-end bearing is sealed, it is suitable for the end of shaft with bearing the small axial sliding force.
◎Model HK, TA, TLA, open-end drawn cup needle roller bearings with retainer,
◎Model BK close end drawn cup needle rolle bearing with retainer,
◎Model SCE, BA, J, JH, drawn cup needle roller bearings (Inch series).
◎This kind bearing consists of full of needles extending to outer raceway, thus bearing high load. It is applied to the situation where the devices mounted with needle roller bearings run in swinging operation with low and middle speed. Since the bearings are fed with lubricating grease when are delivered, it is unnecessary to add the lubricating grease in assembling.
◎Model F, FH open-end drawn cup needle roller bearing with full of needles,
◎Model MF, MFH hole -sealed drawn cup needle roller bearing with full of needles,
◎Model FY open-end drawn cup needle roller bearing with full of flat-head needles,
◎Model MFY close-end drawn cup needle roller bearing with full of flat-head needles
◎The sealed drawn cup needle roller bearing is mounted with sealing lip. In general, the sealing lip can protect bearing from penetration of impurities and leakage of lubricating grease. The seal ring is made of synthetic rubber with operating temperature in -20C-120C. The bearings are fed with high-quality lithium base grease. In addition, it is standard design for drawn cup needle roller bearing without oil hole and doublerow drawn cup needle roller bearing with oil hole. It should be stated in order if changed.
