Schaeffler provides tailor-made bearing technology and services for the paper industry. Schaeffler has extensive expertise. Thanks to decades of cooperation with the world's largest paper machine manufacturers and maintenance production departments, many paper mills benefit from Schaeffler's solutions, which make it possible to increase production speed economically and safely with maximum reliability.
Paper machines are giants in the field of mechanical engineering: lengths of 200 meters and widths of 10 meters are not uncommon. In just one minute, nearly 2,000 meters of paper fly through the machine on rollers and drums for about 120 kilometers. The rolling bearings used here are subject to extremely high requirements in terms of humidity, heat, shaft deflection, high speed and long life. Only extremely reliable rolling bearings can achieve the best paper quality. The bearing arrangement work is more complicated, so it is necessary to innovate. Through continuous product maintenance and further development, Schaeffler can almost always meet new challenges with reliable and cost-effective solutions.
The bearing roller conveyor chain is sticky and slippery, and the production line is frequently interrupted, which reduces work efficiency, causes severe corrosion, and shortens the service life.Treatment method for sticky and slippery bearing roller conveyor chain:Even if the bearing roller conveyo
1. Mechanical damageIn severe cases, metal peeling and large-scale messy scratches occur on the contact surface; generally, bearing mechanical damage refers to the presence of grooves of varying degrees on the alloy surface of the bearing. The main reason for the mechanical damage of the bearing whe
Beryllium oxide: Beryllium oxide not only causes a large loss of steel, but also reduces the surface quality of forgings and the service life of forging dies. If it is pressed into the metal, it will cause the forgings to be scrapped. Failure to remove beryllium oxide will affect turning.Decarburiza
The normal operation of bearings is inseparable from effective lubrication, but the harm of water to bearings may not be taken seriously by everyone. In fact, water has a great impact on the life of bearings. Only a small amount of water (close to 500ppm) can greatly reduce the life of rolling beari
Installation method: When using a tight fit inner ring, the installation method depends on whether the bearing has a straight or tapered bore. Then install the lock washer and lock nut or clamping end cover to fix the bearing on the shaft shoulder. After the bearing cools down gradually, tighten the
1. Bearing radial loadThe bearing that mainly bears radial load is the radial bearing. The nominal contact angle of this type of bearing is a0<=45 0="" br="">N-type and NU-type cylindrical roller bearings can only bear radial loads, and other types of radial bearings can bear both radial loads and a
