⚙️Product Description:
The BB15-K series (also designated as BB15-1K-K / 15x35x11mm) is a precision sprag-type one-way clutch bearing integrated within a standard 6202 deep groove ball bearing envelope, featuring a precision-machined inner ring keyway connection. Featuring a 15mm inner bore, 35mm outer diameter, and 11mm width, this freewheel unit allows free rotation in one direction while locking instantly to transmit torque in the opposite direction with zero backlash. The internal keyway (4×1.8mm) on the inner race ensures positive, slip-free mechanical locking directly onto keyed drive shafts. We supply these high-torque backstop clutches under our proprietary RMO brand while offering flexible global multi-brand OEM procurement for automated machinery and transmission equipment builders.
⚙️Product Features:
- Inner Ring Keyway Positive Locking: Machined DIN keyway on the inner race (BB15-K / BB15-1K-K designation) guarantees slip-proof mechanical torque transmission directly on keyed shafts.
- Instantaneous Zero-Backlash Engagement: High-precision sprag friction blocks deliver immediate locking engagement without rotational lag or slip angle.
- Standard 6202 Bearing Envelope Dimensions: Compact 15x35x11mm form factor seamlessly drops into standard 6202 bearing seats, saving dynamic housing space.
- Dual Functionality (Bearing + Clutch): Combines radial load support from deep-groove ball architecture with unidirectional overrunning clutch torque control in a single unit.
⚙️Product Application:
Engineered for precise indexing, backstopping safety, and smooth overrunning motion, the BB15-K clutch bearing is widely specified in:
- Printing & packaging machinery: flexographic press feeder drives, intermittent paper indexing, and cartoning pushers.
- Material handling & conveyors: inclined belt conveyor anti-backstops, bucket elevators, and sorting line stop-gates.
- Fitness & sports equipment: rowing machine flywheel drives, spin bike magnetic resistance spools, and stepper pedals.
- Textile & agricultural machinery: weaving machine tensioners, seed drill metering shafts, and automated labeling rotators.
⚙️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. |
