BREU SERIES CAM CLUTCH Backstop
Product Introduction
1. BREU series is a modular type Cam Clutch which is delivered as a BREU series Basic type or BREU-K series with option parts (E1, E2, E5, E7 flanges, E3 Torque arm and E4 cover) which are required as separate parts.
2. All models are pre-greased.
The operational temperature range is -40°C to +40°C.
Too much additional grease to both bearing inhibits the basic Cam Clutch function. Refer to page 63 for the maintenance.
3. We recommend a Shaft tolerance of h7, and DIN6885.1 keyway is standard.
4. We recommend tolerance of B and E H7 or H8 for sprockets, gears and other fitted parts.
5. Clean the surface of both end of the outer race and the contact surfaces of the flanges, torque arm and cover.
6. Verify the direction of rotation and attach the flanges, torque arm or cover.
7. When installing sprocket, gear, and other equipment to the clutch, fit them on the surface of the flange by using hexagon socket cap screws.
8. By installing each option part on the opposite side, the direction of rotation can be changed.
9. Fix the grease nipple and set screw to the option parts.
10. When mounting the clutch onto the shaft, apply pressure to the inner race but never to the outer race. Tap the inner race lightly with a soft hammer moving around the race circumference so the Cam Clutch moves slowly and uniformly onto the end of the shaft.
11. Do not use grease that contains EP additives.
Lubrication
BREU series Cam Clutches need periodic maintenance and lubrication to both bearing to provide maximum performance throughout their service life. Lack of prescribed maintenance and lubrication will shorten the Service life of Cam Clutch and may cause unnecessary mechanical damage.

Installation and Usage
1. BREU-(K) C series Cam Clutch couplings make use of BREU series Cam Clutch and CR type couplings without cover.
2. Mount the clutch loosely on the high-speed shaft at first.
3. Accurately align both sprockets by checking with a straight edge on the teeth of both sprockets.
4. Check whether the clearance(S) between the two sprockets is correct, then wrap the chain around the sprockets.
5. Specify right hand (RH) or left hand (LH) as inner race overrunning direction from the view of cam clutch side.
6. The same lubrication as for Tsubaki roller chain is necessary for the coupling chain.
7. Ensure that the chain is properly closed with a connecting link and that the closed of the spring clip is installed in the same direction as the rotation of the outer race.
