High temperature grease:
Fluorine soap based grease; The maximum working temperature of grease can reach 200 ℃. If you need 300 ℃, please contact us.
Internal clearance:
When producing spherical bearings, LDK always assembles the inner and outer rings and steel balls together based on the specific internal clearance. In case of high temperature working environment, proper internal clearance plays a vital role in compensating the thermal expansion of bearings, shafts and seats. The internal clearance standard of LDK for high-temperature bearings is C4.
Silicone rubber sealing ring:
Most standard bearings use nitrile rubber seals. Nitrile rubber is an excellent choice for operating temperatures between 0-100 degrees Celsius. However, when the temperature is higher than 100 ℃, the nitrile rubber will start to be damaged and split, and then no sealing elements can be left to maintain high-temperature lubrication. Silicone rubber has the characteristics of high temperature resistance, especially in the high temperature state for a long time, and it is shockproof, ozone proof, sunlight resistant and can resist the invasion of external moisture. The use of silicone rubber seal ring ensures that high-temperature grease can well lubricate the bearing.
Galvanized retainer:
In order to ensure that the silicone rubber can work normally as a seal ring, LDK uses a galvanized retainer ring on the surface to protect the silicone rubber seal ring. The purpose of the retainer is not only to protect the seal ring, but also to protect the steel ball and retainer from pollution. The use of standard retainer in high-temperature working environment can protect the bearing at first, but it is likely to be corroded, leading to quality problems of the bearing in advance. The galvanized retainer used by LDK has two important characteristics. Heat resistant and abrasion resistant. These characteristics will enable the bearing to run smoothly and continuously in case of high temperature.
