According to statistics, up to 60% of equipment and machinery failures are primarily due to improper lubrication in high-temperature environments. This is especially true for electric motors. Therefore, the role of high-temperature bearings in electromechanical systems is extremely important. However, not everyone knows how to choose the right high-temperature grease to maximize its effectiveness and meet specific needs. Let’s explore this further in the article below.
The Uses of Heat-Resistant Bearings in Electromechanical Systems
Heat-resistant bearings in general, and heat-resistant grease for electric motors in particular, have many significant uses. They are indispensable in all industries and for any motor or equipment. The main uses of heat-resistant bearings for motors are:operating temperature
-
Reduces friction and wear on bearings in gearboxes, rollers, and electric motor shafts.
-
High-strength, wear-resistant steel material.
-
The lubricating grease creates an oil film that insulates metal parts from direct contact with the bearings in the electric motor.
-
Cools and seals the rotating shaft components, preventing dust, dirt, and other damaging agents from entering and damaging the machine. The motor will operate more smoothly, durably, and efficiently.
Heat resistant bearing up to 250°C (T250X)
GMW deep groove ball bearings with the suffix T250X are an extended version of the T250 series, featuring an additional manganese phosphate coating and suitable for medium speeds with temperatures up to 250°C. All T250X deep groove ball bearings offer the following advantages:
-
Manufactured from AISI 52100 steel.
-
The C4 gap design compensates for deformation caused by temperature.
-
Stable operation even at temperatures up to 250°C (the bearings still function stably even up to 280°C).
-
The manganese phosphate (Mn3(PO4)2) surface coating (according to EN ISO 9717) ensures enhanced corrosion protection.
-
Special high-temperature polytetrafluoroethylene (PTFE) grease for smooth movement.
-
The roller cage, made of riveted sheet steel, provides high stability but low friction.
The full range of product codes includes:
-
6000 … 6022
-
6200 … 6222
-
6300 … 6322
-
There are several type options: No grease shield (Open), two heat-resistant steel caps (2Z), or Acrylonitrile Butadiene (NBR) rubber caps (2RSH).
Heat resistant bearings up to 200°C (T200)
GMW deep groove ball bearings with the suffix T200 are suitable for high rotational speeds and temperatures up to 200°C. All T200 deep groove ball bearings have the following advantages:
-
Manufactured from AISI 52100 steel.
-
The CN or C3 gap design compensates for deformation caused by temperature.
-
Capable of handling temperatures up to 220°C (effective operating temperature 200°C).
-
Special high-temperature grease (diurea thickener and mineral oil) for smooth movement.
-
The roller cage, made of riveted sheet steel, provides high stability but low friction.
