Heat-resistant bearings
Bearings with operating temperatures above 150°C are called high-temperature bearings. With special design, easy operation at temperatures up to 400°C (750°F). Heat-resistant bearings are a line of balls manufactured to solve problems related to high temperature environments, dry environmental conditions. Has option slow rotation speeds and fast speeds for choose
Grease high-temp Nano
Nano Lube® High Temperature, Extreme Pressure Grease and a temperature range from 150°C to 350°C, It is ideal for use in manufacturing facilities where safety, thermal stability, performance and extended service life are critical lubricant requirements. It is resistant to detergents and salt water, will not dry out, resists corrosive chemicals and will not separate.
Our grease lubrication are sourced from Europe and certified according to the standard 91/155 EEC
CASE STUDY
Multi-industry applications
GMW temperature bearings are specially designed for work applications in high temperature conditions.
All our GMW bearings are made of AISI 52100 steel and incorporate the most suitable greases for each thermal grade as a lubrication solution.
Our GMW temperature bearings are especially useful for applications in conditions subject to high temperatures such as trucks used in kilns for brick making, in furnaces for the ceramic industry, in rollers in working conditions at elevated temperatures in the steel manufacturing industry , aluminum manufacturing, glass manufacturing, Steel industry, Etc.
Iron and steel industry
Ordinary steel bearings don’t last long in high temperature environments like steel making. The casings expand, the polymers in the cage degrade and lubricants evaporate. Any one of these elements can cripple a bearing and halt production, never mind all three occurring at the same time. So GMW has developed a range of special bearings designed exclusively for use in ultra-high temperature applications such as steel making. With special materials, special cages, and special lubricants
Die-casting, Aluminium manufacturing
In the high pressure casting process, molten aluminum or aluminum alloy is scooped from the furnace and filled into the mold at high speed and pressure.
Depending on the metal used, the part scoops the material into the mold continuously with the molten metal at a temperature range of 600° C – 700° C
The GMW 350°C is manufactured with a one-piece, high performance, low friction cage. The manganese phosphate coating of the GMW 350°C helps the bearing ensure corrosion resistance and good adhesion of lubricants. will ensure equipment is operated safely and effectively in production
High temperature rollers
GMW high temperature bearings and bearing units are designed to deliver increased reliability, reduced complexity and decreased environmental impact in operating temperatures up to 400 °C (750 °F), making these products very suitable for applications in kiln trucks, roller hearth furnaces, and bakeries. Because GMW high temperature bearings correspond to the ISO dimensions of grease-lubricated bearings, production efficiencies and cost savings can be realized with a simple change to the GMW bearing solution.
Heating Pumps, Motor
There is always some fluctuation in the operating temperature of bearings within motors. Individual operating temperatures depend on elements such as the application of the motor and the ambient temperature. However, as a guide, 170°F or 80°C should be considered normal. As the temperature increases from this point, so does the risk of severe failure and motor damage.
At 190°F or 90°C, temperature alarms should engage. It is important not to ignore them and to take immediate action to find and treat the cause of the temperature rise
GMW bearing high-temp help
1) Prevents metal corrosion.
2) It can prevent the entry of foreign objects and seal the game.
3) Discharge friction heat, discharge slope temperature rising too high.
4) Reduce friction and wear, prolong bearing life.
The Secret of Success
GMW High-temp Deep Groove Ball Bearings
Depending on the used grease, perfect running performance for normal bearings is on guaranteed up to maximum of 150°C. GMW High-temp Deep Groove Ball Bearings allow temperatures up to 400°C at low speeds.
Advantages:
Increased radial clearance (multiple of C5) compensation for temperature-induced deformations of the production goods (rails, transport units)
Riveted sheet steel cage provides high stability at low friction
Manganese phosphate coating (according to EN ISO 9717) ensures increased protection against corrosion, good adhesion of lubricants and better runability.
All HT1, HT, HT3, HT4, T150, T200, T250 and T250X – bearings are available open, with steel (2Z) (Z) (2RSH) shield on one or both sides
Lubricants:
GMW offers four standard lubricants for High-temp Deep Groove Ball Bearings. Additionally, our coated bearings can be filled with individual grease as required by the customer
Our grease lubrication are sourced from Europe and certified according to the standard 91/155 EEC
