⚙️Product Description:
Seeking a compact 15mm directional control solution that delivers instant torque lockup without relying on housing press-fits? The CSK15PP One-Way Sprag Clutch Bearing (15x35x11mm) is the industry benchmark for precise backstopping, indexing, and overrunning operations. Dimensionally identical to a standard 6202 bearing, the CSK15PP features a specialized sprag mechanism internally and incorporates dual DIN 6885.3 keyways on both the inner and outer rings (“PP” designation). This eliminates the thermal expansion risks and torque slippage of press-fitted assemblies, enabling direct key-locking to shafts and housings. As a dominant B2B bearing trading power, we offer versatile sourcing solutions: slash component procurement costs with our field-tested RMO proprietary brand, or task us to source authentic European premium brands (such as Stieber or Ringspann equivalents) for your high-precision OEM machinery.
⚙️Product Features:
- Dual Keyway Positive Locking (PP Architecture): Precision-machined keyways on both the 15mm bore and 35mm outer diameter ensure positive mechanical torque transmission (~18 Nm rated torque) without requiring interference housing fits.
- Instantaneous Sprag Engagement: Internal sprag elements wedge frictionally between raceways upon reverse rotation, delivering zero-backlash backstopping and instantaneous free-wheeling action in the opposite direction.
- Standard 6202 Footprint Compatibility: Maintains the classic 15x35x11mm dimensions, allowing machinery designers to directly upgrade standard rotating shafts into smart one-way drive systems without expanding gearbox envelopes.
- Pre-Lubricated & Maintenance-Free: Supplied pre-greased for immediate installation, using high-performance lubricants designed to reduce friction coefficient during high-speed overrunning phases.
- Flexible Dual-Channel Trade Sourcing: We streamline your B2B supply logistics. Wholesale container volumes of cost-effective RMO stock for the industrial repair market, or order specific traceable international freewheel brands for specialized OEM builds.
⚙️Product Application:
Masterfully engineered for unidirectional control and anti-reversal safety, the CSK15PP series is indispensable for:
- High-speed packaging machinery, labeling machines, and automated indexing feeds.
- Printing presses, textile machinery feed rollers, and paper converting equipment.
- Incline conveyor systems, bucket elevators, and material handling backstops (preventing reverse load runaway).
- Commercial fitness equipment, rowing machines, and exercise bike flywheel drives.
- Specialized B2B power transmission distributors and automated machinery repair shops globally.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
