| HSB drawn cup needle roller bearings is formed with thin steel plate through precision punching with very sectional height and big load capacity.This kind of bearings are especially applicable to the big quantity production with economic demands. Stable combination is used between the needle bearings and the bearing cage.No axle fixture is required.Even under high speed and heavy load condition,the bearing functions can be fully maintained.Furthermore,no lubricating for a long time is possible due to its high storage volume of grease. |

| Drawn cup needle roller bearings | ||
HSB drawn cup needle roller bearings is composed of thin wall punched outer ring,retainer and a group of needle rollers.To compare with the Piercing drawn cup needle roller bearings with open ends,this is a kind of sealed bearing with one end sealed.This kind of bearinBs are applicable to the shaft ends with small axial moving force. | ||
| Sealed drawn cup needle roller bearings | ||
The sealed drawn cup needle roller bearings has a sealing lip.Under general condition,it can protect the dirt from entering into the bearing and the lubricant leakage.The sealing ring is made of compound rubber with operational temperature of -20ºC-120ºC The bearings have been filled with quality lithium based grease when supplied.Furthermore the standard designing of the drawn cup needle roller bearing is non-oil hole,while the double row drawn cup needle roller bearings are designed with the standard of oil holesk.Should there be any option,please notice us in orders. | ||
| Full complement needle roller type drawn cup needle roller bearings | ||
This kind bearings are composed of full width needles which extend outside of the outer rings.Therefore it will sustain heavy load and is suitable for the rocking action of low and medium speed.The bearings can be used instantly once it is assembly because lubricating grease is filled in the bearing before supplied. | ||
| Mounting | ||
| Must in press in the bearing box the black sheet ramming forming ramming addendum circle needle bearing addendum circle rear area to be able to obtain the correct shape and the size precision, Therefore, The bearing box size precision and the shape affect directly the bearing inscribed circle, Therefore must gives to the bearing box hole size and the shape fully to take. Installs when this kind of bearing, Uses the pressure which like the chart shows to install the core axis to be convenient, When assembly must use the tool to withstand the bearing the code number printing side to press in, Does not have to use the hammer to strike directly, Core axis size according to following request manufacture; A=D-(0.2-0.3)mmB=Fw-(0-0.025)mm

| The inspection of the drawn cup needle roller bearings | ||
In regard to the dimension inspection of this kind of needle bearings,it is meaningless to measure the single bearing because the bearing will deformed after quenching due to its thin outer ring wall.That is:this kind of needle bearings must be fitted into the bearing cage according to the recommended permissible tolerances before it can reach the vital functional inscribed circle and circularity.So,the following inspection methods are recommended: (1)press the bearing into basic gauge with rigidity shown in the list (the wall thickness is no less than 20mm). (2)check with a feeler gage or taper gage the inscribed circle to see if it falls in the required range. | ||
