HF173516 One Way Clutch Bearing for Treadmill / HF17X35X16 17*35*16 mm

HF173516 and HF17X35X16 are two different marking formats for the identical metric drawn cup one-way needle roller overrunning clutch bearing, unified dimension Fw=17mm matching shaft diameter, outer diameter D=35mm, total width C=16mm.

It belongs to HF series pure clutch unit without built-in bilateral radial needle supports, must be matched with HK17 series drawn cup needle bearings to bear radial load during operation. Integral stamped thin steel outer cup adopts interference press-fit installation mode, no extra positioning sleeves or snap rings required to simplify assembly steps.

Internal stainless steel leaf springs push inclined needle rollers to realize unidirectional torque transmission and automatic anti-reverse self-locking; free rotation in forward direction, rigid locking reverse rotation to eliminate equipment reverse backlash and avoid component damage. Outer shell and needle rollers adopt GCr15 bearing steel with overall quenching treatment, double-end open structure facilitates regular grease replenishment and maintenance. Widely applied to textile winding machinery, packaging conveyor equipment, small gear reducers, treadmill drive parts, office automation transmission assemblies and light industrial anti-reverse overrunning devicesAlibaba.co....

• Ultra-compact thin drawn cup press-fit structure, directly pressed into housing interference hole, greatly simplify equipment transmission layout and reduce spare part stocking varieties
• Independent single-direction overrunning clutch core design, stable locking torque, reliable anti-reverse self-locking performance under frequent start-stop reciprocating torque impact load
• Stainless steel elastic leaf spring positioning needle rollers, uniform wedge locking force, no slippage during torque transmission, long contact fatigue service life
• Narrow radial cross-section saves internal installation space, perfect for miniaturized light-duty unidirectional transmission mechanical design
• Double-end open design facilitates regular lubrication maintenance, effectively reduce abnormal wear caused by insufficient grease supply
• Customizable options: single/double RS rubber dust seals, stainless steel anti-rust outer cup, OEM laser marking, low-temperature food-grade special lubricant filling

Effectively eliminate equipment reverse rotation backlash and reduce transmission system overhaul maintenance frequency

1. Q1: What is the difference between HF173516 and HF17X35X16?
   A1: The two are different industry marking formats of the exact same one-way clutch bearing, dimensions, torque, load parameters and installation performance are fully consistent and interchangeable.
2. Q2: What is the difference between HF series and HFL series one-way bearings?
   A2: HF173516 is independent clutch unit without radial supporting needles, must match HK series needle bearings to bear radial load; HFL integrates bilateral radial needle supports, can work alone without auxiliary bearings.
3. Q3: Can HF173516 bear radial load alone?
   A3: Cannot. It only realizes unidirectional locking function without radial supporting structure, must be combined with HK1724 drawn cup needle bearing to bear radial load jointly.
