⚙️Product Description:
The HFL283625 (28x36x25mm) is an integrated drawn cup needle roller clutch unit engineered with built-in dual radial support bearings on both sides of the central overrunning clutch mechanism. Featuring a 28mm shaft diameter, 36mm outer diameter, and 25mm section width, this space-saving design utilizes a thin-walled cold-rolled steel drawn cup outer ring, high-strength PA66 cages, and precision GCr15 needle rollers. By combining one-way torque indexing/overrunning with complete radial shaft support in a single compact assembly, it eliminates the need for external secondary support bearings. We supply these high-torque drawn cup clutches under our proprietary RMO brand while facilitating flexible global OEM direct sourcing for automotive system and industrial automation manufacturers.
⚙️Product Features:
- Integrated Radial Bearing Support: Built-in needle roller arrays flanking both sides of the central locking clutch eliminate external bearing requirements and save axial space.
- Thin-Walled Drawn Cup Architecture: Precision-formed cold-rolled steel outer cup delivers ultra-low radial section height with maximum torque-to-weight performance.
- Instantaneous Spring-Loaded Engagement: Individual steel leaf springs engage GCr15 needle rollers against shaft ramps for zero-backlash, slip-free torque transfer.
- Lightweight PA66 Retainer Design: Precision-molded PA66 polyamide cage keeps needle rollers perfectly aligned, lowering operational friction and running noise.
⚙️Product Application:
Engineered for compact one-way torque transmission, backlash-free indexing, and integral shaft guidance, the HFL283625 clutch bearing is widely specified in:
- Automotive & mobility systems: starter motor drives, steering column adjusters, and dual-clutch transmission (DCT) actuators.
- Industrial automation & packaging: conveyor indexing rollers, paper feeding mechanisms, and friction-driven belt indexers.
- Office & consumer machinery: high-speed photocopier paper feeds, printing press rollers, and automated ticketing gates.
- Power tools & appliances: cordless drill high-torque gearboxes, lawnmower clutch drives, and washing machine agitator shafts.
⚙️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. |
