ASNU 35 NFS 35 STIEBER Overrunning Clutch Bearing 35*80*31mm

ASNU 35 NFS 35 STIEBER Overrunning Clutch Bearing 35*80*31mm

One-way clutch bearing ASNU Description

Type ASNU is a roller-type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outer diameter is the same as a series 63…Ball bearing.
A typical arrangement is to install this type alongside a bearing within the same location tolerances, as shown on the following page. The inner race is keyed to the shaft.
The outer race has positive n6 tolerance, to give a press fit in a H7 housing. Additional side notches in the outer race provide for positive torque transmission.
If the housing is to K6 tolerance, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly. This design can accept an axial misalignment of inner and uter race of ± S/2.

FAQ1: What difference between the ASNU overrunning clutch and sprag clutch bearings?

The terms overrunning clutch and sprag clutch are often used interchangeably, but there’s a key distinction in the internal mechanism. The STIEBER ASNU series is a type of roller ramp clutch, which is a variant of the overrunning clutch.
Sprag Clutch: Uses specially shaped, asymmetrical metal elements (sprags) that tilt to wedge and engage. The engagement is progressive and uniform across all sprags, providing high torque capacity.
Roller Ramp Clutch (like the ASNU): Uses cylindrical rollers in a ramped raceway. When the driving force is applied, the rollers roll up the ramps and wedge between the inner and outer races. This design is also highly effective but can be more sensitive to high overrunning speeds.
The key difference is the shape of the engaging element and the surface it engages against.

FAQ2: What are the advantages of STIEBER ASNU 35 NFS in Automation Systems?

The STIEBER ASNU 35 NFS is a roller-type freewheel clutch. Its advantages in automation systems stem from its specific design and high-performance capabilities.
Compact Design: Its nominal outer diameter is the same as a 63 series ball bearing, allowing it to be easily integrated into existing machinery alongside a support bearing.
High Torque Capacity: The ASNU 35 can transmit a high amount of torque (383 Nm), making it suitable for demanding applications.
Reliability: It offers quick engagement and disengagement, which is essential for precise control in automated processes.
Positive Torque Transmission: The outer race has side notches that can be used for positive torque transmission, which is an important feature for high-torque applications.
