HF series one way bearing is the most common one way bearing, and have widely acknowledged. However, FC series one way bearing is much more strange for the people. In fact, FC is usually substituted by HF, for example, HF 101612 replaces FC10.
Reasons for replacement:
1: HF is much cheaper than standard FC, but working performance does not have a large difference.
2:Most of the factory fakes HF as FC, because most of the bearing distributor or dealer do not know the difference very much.
R&B bearings will support you to spot the difference in the example of HF 101612 and FC 10 as follows:
1: HF is flat end needle roller; while FC is pointed end needle roller;
2: HF is light series, while FC is heavy duty series one way bearing. It means FC will have higher torque rating than HF, which is the most important factor for one way bearing.
3: There is only one needle roller in each cage window for HF one way bearing; while multi-roller in each cage window for FC one way bearing.
4: Single roller per stainless steel spring for HF one way bearing; while multi-roller per stainless steel spring for FC one way bearing.
one-way needle roller bearing
HFL series drawn cup one-way needle roller bearing has two supporting needle bearing and one roller clutch which shares a punching outer ring, and can be used as a special space-saving support. The two supporting bearing are assembled on both sides of the roller clutch, and endure the radial load. The supporting needle bearing is composed of plastic cage and needles.
Main features: the unidirectional movement, reverse lock; the high conversion frequency and high conversion accuracy.

Under the conditions of using the recommended mounting tolerances, the maximum torque that can be transmitteddepends primarily on the design of the seat shell and the shaft (materials, strength, wall thickness). Only when thewall thickness of the seat shell and its material allowable stress certain requirements, the clutch can transfermoment Md.
Switching frequency:
Because the radial cross-section is thin, so the moment of inertia of the roller clutches is very small. Each needle by a separate spring support, so allowing higher switching frequency. At high frequencies, the driving force is generallypassed through the shaft.
Conversion accuracy:
Since the fixed contact can be maintained between each of the needle by its separate spring support shaft, the bevelof the needle and punch the outer circle, so can achieve a high conversion accuracy.
Installation:
Should be used the assembly mandrel with Needle roller bearings, needle roller clutch pressure holing hole(installed). When the clutch side of the direction of the arrow relative to the shaft is rotated, the clutch will lock, andtherefore should be noted locking direction before installation.
Lubrication:
HF-drawn cup needle roller clutch in oil and grease lubrication. Lubricated with oil, however, before you can get thebest performance, the standard HF-Drawn Cup Clutch has been filled with lithium grease.
Performance test:
The technical requirements of the test method and the standard circle described with Needle roller bearingsdimensional inspection mandrel used nominal size to take the tolerance zone as the lower limit for the h5 shaftalong the arrow in the opposite direction in the clutch can be locked.
Mounting tolerances:
The technical requirements of the seat shell HF-Needle roller bearings, the axis of the tolerance zone h5, the surfaceroughness Ra0.2m, not less than the hardness of HRC60.
Operating temperature:
HF-drawn cup needle roller clutch lubrication properly can the temperature range of -30 ° C to +120 °C long-running,short-term up to 150 ° C Operating Temperature. Lithium Grease Run
