GCR15 bearing roller supplier

Category:

Rollers for crossed-roller linear guides（V series）

Keywords:

The grease will become soft when rotating at high speed, causing leakage. When there is vibration, the grease will be squeezed and thrown from the raceway, and the soap structure of the grease will mechanically disintegrate and cause the grease to be destroyed or even thrown out. GCR15 bearing roller.

1.Never mix incompatible oils and fats. If two incompatible oils are mixed, the consistency will usually become soft, and eventually the oil will be easily lost and cause damage.
2. Oil seal is the gateway that contains grease and GCR15 bearing roller from external pollution. Many GCR15 bearing roller in the industry only use ball cages, some use metal oil seal systems, and some are completely open due to automatic refueling systems. , And bicycles usually cannot use such GCR15 bearing roller, otherwise the end of life will be declared only after the first cycle of grease exhaustion or pollution, and metal oil-sealed GCR15 bearing roller can also avoid pollution for a longer period of time, and Can play an oily role.
3. The grease will become soft when rotating at high speed, causing leakage. When there is vibration, the grease will be squeezed and thrown from the raceway, and the soap structure of the grease will mechanically disintegrate and cause the grease to be destroyed or even thrown out. GCR15 bearing roller.
4. The grease used in GCR15 bearing roller has anti-rust properties. The anti-rust performance mainly depends on the solubility of the grease. The grease formed by different viscosities and different materials has different levels of anti-dissolution and anti-rust properties.
