DKFL ASNU 60 Freewheel Clutch
The DKFL ASNU 60 one-way clutch is an industrial roller-type freewheel designed without internal bearing support (non-bearing supported). This means that radial and axial loads must be supported by auxiliary bearings installed alongside the unit within the same housing and tolerance limits. The outer diameter of this model matches standard Series 63 (size 6312) ball bearings, allowing for compact and efficient coaxial layouts in heavy machinery.

Product Detail
DKFL ASNU 60 Roller Type Freewheel & One-Way Clutch Non-Bearing Supported | 60mm Shaft Diameter | Dimensionally Interchangeable with Series 63 Ball Bearings
The DKFL ASNU 60 roller-type freewheel and backstop clutch delivers reliable holding torque (1825 Nm) and standard dimensional compatibility with series 63 bearings, engineered under strict DKFL quality standards and distributed by Kamyar Gostar Iranian Co. (KGICO).
Technical Overview of DKFL ASNU 60 Freewheel Clutch
The DKFL ASNU 60 one-way clutch is an industrial roller-type freewheel designed without internal bearing support (non-bearing supported). This means that radial and axial loads must be supported by auxiliary bearings installed alongside the unit within the same housing and tolerance limits. The outer diameter of this model matches standard Series 63 (size 6312) ball bearings, allowing for compact and efficient coaxial layouts in heavy machinery.
The inner race features a keyway for positive torque transmission on the 60 mm shaft. The outer race is engineered with an n6 press-fit tolerance and side notches to guarantee reliable torque transmission to the housing without slipping. This versatile unit excels as a backstop, overrunning clutch, or indexing element in demanding industrial power transmission applications.
Designation & Structural Features (DKFL ASNU 60)
"ASNU" Series: Designates standard industrial roller-type freewheels without internal bearing support, featuring outer dimensions matching series 63 ball bearings.
Size "60": Indicates the nominal inner diameter (bore) of 60 mm for precise shaft mounting.
Roller Mechanism: Precision spring-loaded rollers lock instantly in one direction and overrun smoothly with minimal friction in the opposite direction.
Positive Torque Transmission: Inner race keyway combined with outer race press-fit tolerances and lateral notches prevents slippage under high operational loads.
DKFL Brand Quality: Manufactured using premium wear-resistant alloy steels, supplied and fully supported by Kamyar Gostar Iranian Co. (KGICO).

Common Industrial Applications
- Industrial Conveyor Systems: Acting as a backstop to prevent accidental load reversal during power outages or shutdowns.
- Industrial Gearboxes & Vertical Elevators: Securing loads in material handling lifts and industrial hoists.
- Packaging Machinery & Industrial Presses: Utilizing indexing mechanisms for precise intermittent feeding.
- Mining & Crushing Equipment: Absorbing high shock loads and preventing reverse rotation in drive drums.
- Dual Pumps & Multi-Drive Systems: Automatically decoupling motor speeds in complex power train setups.
Installation Guidelines & Engineering Warnings
Since the ASNU 60 freewheel is non-bearing supported, it must be installed adjacent to a standard bearing (such as a series 63 ball bearing) within the same housing to properly accommodate radial and axial loads.
An H7 or K6 housing tolerance is recommended for the outer race. The housing must possess sufficient rigidity to prevent expansion after assembly, ensuring unhindered roller engagement.
Rotation Direction & Lubrication
Verify the required locking and overrunning direction (clockwise or counterclockwise) relative to your system layout prior to final assembly. Proper oil or grease lubrication suited for the operational overrunning speed is mandatory.
Frequently Asked Questions (FAQ)
1. Why does the ASNU 60 clutch require an auxiliary bearing?
This freewheel is designed as "non-bearing supported," meaning its internal structure cannot sustain radial or axial shaft loads independently. These forces must be borne by adjacent auxiliary bearings.
2. What does dimensional interchangeability with series 63 bearings mean?
Its outer diameter and width are identical to standard series 63 ball bearings (size 6312), allowing designers to mount the clutch directly alongside the main bearing within a single shared housing.
3. What is the primary industrial application of the ASNU 60?
Its most common application is as a backstop in heavy inclined conveyors, industrial elevators, and power transmission setups requiring foolproof prevention of reverse motion.
