6205DU NSK bearing price list 6205 2rs deep groove ball bearing

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
