Japan TSUBAKI BB series Cam Clutches One way Bearing BB40-2K-K

Japan TSUBAKI BB40-2K-K Cam Clutches BB40-2K-K

One-way clutches are efficient mechanical devices that utilize differences in axial rotating direction and the speed of rotation to prevent reverse rotation and ensure safety.

In order to create a more reliable uni-directional clutch, engineers have spent many years developing and improving clutches, from the simple prop type, to the ratchet type and the roller type, and then culminating to the Cam Clutch, which has become the mainstream.

The TSUBAKI Cam Clutch introduced here is a cam-type, one-way clutch that is the leading clutch of today.BB series clutch has the bearing characteristics and dimensions of #62 type ball bearing. This design provides easy handling and installation. Ideal for general applications.

1. BB series Cam Clutch is designed for press fit installation.

2. BB-1K-K and BB-2GD 1K-K series have a keyway on the inner race. Keyways, except size 25 are manufactured to DIN 6885. 3, BB40-1K-K and BB40-2GD 1K-K are manufactured to DIN 6885. 1.

3. BB-2K-K series has a keyway on both the inner and outer race. “-K” means keys shipped together with Cam Clutch.

4. Correct interference dimensions at the shaft and the housing must be maintained to obtain maximum bearing and clutch performance.

5. BB, BB-1K and BB-2K Clutches, bearing supported and delivered with grease have dust seal protection against particles of 0.25mm and over, whereas BB-2GD and BB-2GD-1K clutches, 5mm wider than standard BB series, have special lip seals for effective protection against any dust.

6. The arrow on the inner race shows the direction of inner race engaging.

7.To install the clutch, use a press tool of the appropriate diameter to apply even pressure over the entire face of the inner and outer race.

8.Do not hammer or apply other shock to the clutch.

9.Make sure the housing has enough strength to withstand the pressure required for the press fitting installation of the Clutch.

10.Operating temperature range: –30°C to +100°C (Consult us for the temperature that exceeds this range).

Lubrication

1. Since grease is already applied before delivery, there is no need to apply 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.

Feature

1.Compact design

With the function of one-way clutch and bearing In a small space , effectively use of space.

2.Easy to install

For the installation of the shaft or shell, there are two locking methods--Pressing lock and key lock.

3.Lifting torque capacity

A large number of cams are arranged between the inner and outer rings, which can transmit more torque than the shell-shaped roller clutch.

Applications

From low to high speed, widely used, suitable for small, light load applications. The model with oil seal is most suitable for dusty and leakproof occasion. Torque: 29 to 260 N · m (3.0 to 26.5 kgf * m)
