Special one-way bearing D49A with grooves D49A one-way bearing 20*60*20MM bearing steel one way clutch bearing BB series
One way bearing D49A introduction :
D49A one way bearings is a sprag type freewheel , integrated into 6200 series ball bearing(except sizes 8 and 40), Also named OW BB KK etc. It provides you an one way clutch, and eliminates the need for a ball bearing. It gives a high degree of freewheeling accuracy while utilizing a minimum of space. It is bearing supported, shipped grease lubricated and protected against dust larger than 0.3mm diameter. Torque transmission is ensured by a press fit assembly into a rigid outer housing with N6 tolerance, and onto a shaft with n6 tolerance. The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified. Operating temperature range:-20°C to +100°C. Peaks up to +120°C are acceptable for short periods.
Lubrication
1. Since grease is already applied before delivery, there is no
need to apply and grease before use.
2. If the clutch is used with an oil lubricant, the oil lubrication
should be applied inside the unit always.
3. Do not use greases or lubricants with EP additives.
