High Temperature Bearings
Bearings with operating temperatures above 150°C are high-temperature bearings. With special design, easy operation at temperatures from 150°C (302°F) up to 400°C (752°F). High-temp 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
High Temperature Grease
High Temperature grease, 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

Our grease lubrication are sourced from Europe and certified according to the standard 91/155 EEC
High-temp Deep Groove Ball Bearings for low speeds
High-temp Deep Groove Ball Bearings are especially coated bearings with an increased radial clearance. These products are usually used in applications with very high temperatures maximum to 400°C and slow speeds
High-temp Deep Groove Ball Bearings for fast speeds
GMW offers heat stabilized Deep Groove Ball Bearings, which are suitable for high temperatures to a maximum of 250°C and fast speeds.
High-temp Radial Insert Ball Bearings for Low speeds
GMW offer High-temp Radial Insert Ball Bearings are especially coated bearings with an increased radial clearance. These products are usually used in applications with very high temperatures to a maximum of 350°C and slow speeds.
High-temp Radial Insert Ball Bearings for fast speeds
GMW offers heat stabilized and coated Radial Insert Ball Bearings, which are suitable for high temperatures to a maximum of 250°C and fast speeds.
High-temp spherical roller bearings
GMW offers open heat stabilized Spherical Roller Bearings, which are suitable for high temperatures to a maximum of 250°C and fast speeds.
Depending on the temperature inside the application, there are two versions: open and two Viton seals as standard (2RS1)
High-temp tapered roller bearings
GMW offers high-temp Tapered Roller Bearings . They are mounted in pairs in order to obtain a bearing unit sealed at both sides. The maximum operating temperature is 200°C
They are also coated with Manganese Phosphate on the roller, cage rings and possibly the entire product surface
High-temp Cam Followers for low speeds
High-temp Cam Followers with bushings outperform special grease or oil lubricated. GMW cam followers for high temperature up to 300°C. All High-temp Cam Followers come with the following benefits: Material AISI52100, Increased radial clearance (multiple of C5)
Manganese phosphate coating (according to EN ISO 9717).
Temperature conveyors, and steel mill equipment are typical applications.
High Temperature Grease
GMW uses only high-quality lubricants made by well-known manufacturers. Besides the temperature related standard lubricants, we also offer an extensive range of special grease options as well as individual lubrication as required by the customer on request.

Our main product range includes High-Temp deep groove ball bearings, High-Temp taper roller bearings, High-Temp spherical roller bearings, High-Temp Radial Insert Ball Bearing, High-Temp Cam Followers. Which can handle temperatures from 150ºC to 400ºC
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 fast 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 suffix HT1 (350°C) is manufactured with a one-piece, high performance, low friction cage. The manganese phosphate coating of the GMW suffix HT1 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 from 150°C (302°F) up to 400°C (752°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.
