Notes:

1. T max = 2 × T KN

2. Inner race overruns

3. Outer race overruns
Keyway to DIN 6885.1

Mounting

1. When mounting sprockets or gears to the outer race, use the outer race inner dimension (dimension E) to

make a centering flange on the sprocket or gear. Then attach firmly with bolts of tensile strength 10.9 or greater

to the tapped holes in the outer race. Recommended tolerance between mounted gear and centering flange is f7.

2. The recommended shaft tolerance is h6 or h7.

3. Always use a parallel key, and do not use a tapered key. A parallel key meeting ISO R773 (DIN 6885.1) is

recommended. Make sure that there is no lateral play between the key and keyways. Install an end plate on the

face of the inner race

4. When inserting the shaft, apply pressure only to the face of the inner race only.
