HFL0615 Drawn cup needle roller bearings clutch 6x10×15mm

The drawn cup needle roller clutch HFL0615

Demension:6×10×15mm,    Weight: 4.0g.

SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;

Outer ring fordrawncup needle roller bearings(DC type) is made of cold rolled steel strip accurately 

formed.Structure of DC needle roller bearings features space saving and higher capacity.They are suitable 

for applications with limited space and housing not hard enough to act as raceway. No requirement on axial 

location when the DC needle roller bearing is pressed into the housing.

In most applications inner ring is not necessary for DC needle roller bearings unless shaft raceway is 

impractical,standard inner rings for DC to compare with open end DC needle roller bearings, close end DC 

needle roller bearings are good for sealing at the close end of bearings,operating temperature range for 

bearings grease lubricatedare 20℃ to +120℃.

1.The drawn cup needle roller clutch is the overriding clutch (one-way clutch), composed of the outer ring

punched with the high-quality steel sheet, plastic retainer, spring and needles, used for transferring one-

way torque.The drawn cup needle roller clutch has not the load carrying feature by itself. However it can 

play the action in combination with Model HK and BK drawn cup needle roller bearing. The drawn cup needle 

roller clutch is the block bearing either withstanding the radial load or transferring torque.

2.Inspection the enveloping circle diameter

The dimensional accuracy of drawn cup needle roller bearings cannot be measured before fitting

without a ring gauge as the thin-walled outer ring can be out of round due to the manufacturing process.The

bearings obtain the accuracy required for their correct function only when pressed into ahousing bore which

must be manufactured with the recommended tolerance limits.

The enveloping circle diameter can then be checked as follows:

a.Press the bearing into a steel ring gauge(wall thickness≥20mm).The bore dimension of the ring

gauge must correspond to that given.

b.Measure the enveloping circle diameter with cylindrical go and no-go gauge plugs.
