Guide Bearing-U Groove, Stainless Steel

・Deep groove Ball Bearings is the most commonly used rolling bearing. It is of simple structure and easy to use.
・The material of this Ball Bearings is equivalent to SUS420, which has a certain antirust ability.

・The U-shaped roller is generally used for round belt transmission, which can achieve high linear speed.
・The U-shaped groove of the Ball Bearings can prevent belt deviation and improve transmission accuracy.
・The use of U-shaped rollers can reduce the accuracy requirements of the installation reference, greatly reducing the accuracy requirements for the installation reference plane, and saving assembly time and effort.

When the precision of the shaft and Ball Bearings housing is poor, the bearing will be affected, and its due performance will not be exerted. For example, the poor precision of the mounting part with the bearing will cause relative inclinationof the inner and outer rings.
At this time, besides the Ball Bearings load, the edge load will be increased additionally, which will shorten the fatigue life of the bearing, and even more seriously, it will lead to damage such as cage breakage and sticking.

Please use the following special mounting tool for installation and removal

Bearing heater

Proper installation of the Ball Bearings heater can guarantee a long life of the bearing. Rolling bearings are reliable mechanical components with long service life if they are installed and maintained correctly. After the induction heater is used for heating, the bearing expands outward in the cylindrical direction, which can avoid the damage during installation. Induction heater is one of the most scientific heating methods, which does notneed preheating, and can be heated to 110℃ in a few seconds or minutes depending on the weight of bearings, without damaging the prior lubrication

 

Bearing puller

When the installation state of the Ball Bearings is in the following situations, the special puller can be used for disassembly. (a) Shaft shape: cylindrical shaft, Inner diameter shape of bearing inner ring: cylindrical hole. (b) Shaft shape: cylindrical shaft, inner diameter shape of bearing inner ring with tight bushing: tapered hole. (c) Shaft shape: tapered shaft, Inner diameter shape of Ball Bearings inner ring: tapered hole. In either state, the lock nut of the shaft (or the lock nut of the tight bushing) must be released during disassembly, and the lock nut must beplaced in a loose state.
