Needle roller bearings have relatively small diameter cylindrical rolling elements whose length is much larger than their diameter.
Compared with other types of rolling bearings, needle roller bearings have a small cross-sectional height and significant load-bearing capacity and rigidity relative to their volume. Also, because the inertial forces acting on them is limited, they are an ideal choice for applications
with oscillating motion. Needle roller bearings also work well in compact and lightweight machine designs and they serve as a ready replacement for sliding bearings.
SPECIAL NOTES
• HFL series has two integral radial bearings arranged on both sides of needle roller clutch. They can therefore support radial forces in particularly space-saving bearing arrangements.
• Plastic springs (HFL...KF) are available for some sizes.
• Partially knurled outer ring (HFL...R) is available upon request.
• A special tool is suggested when assembling the clutch and bearing assembly. For details please contact our engineers.
• Only after the clutch and bearing assembly has been pressed into the hole of the housing, the drawn thin-walled outer ring could then obtain its final dimension and geometric accuracy.
• The transmissible torque and the stresses which can be taken by the housing are subject to the material and the wall thickness of the housing, and such data is needed upon enquiry.
• The clutch and bearing assembly can be normally used in temperature range from -30°C to 120°C. For the working environment above 70°C, oil lubrication is recommended.
