Today, I'd like to tell you about the filling amount of bearing grease. So how much lubricant is appropriate? There is often a misunderstanding that the more the amount is added, the better. In fact, this is incorrect. If the grease is added less, it will not lubricate. If the grease is added more, it will increase the resistance of the bearing, increase the energy consumption, and increase the bearing temperature, which will lead to the oxidation and spoiling of the grease, so it cannot play the role of lubrication. That How much grease is good to add? The official gives a value, the range should be one-third to two-thirds of the bearing space, and the calculation formula G (gram) = 0.005×D×B is given, D refers to the outer diameter of the bearing, the unit is millimetre, B refers to the width of the bearing, and the unit is also millimetre. Let me give you an example: for example, 6315 bearing, the outer diameter of this bearing is 160 mm and the width is 37 mm. In the formula, 0.005 × 160 × 37 = 29.6 grams, which is about 30 grams, so adding to 30 grams is basically the most appropriate amount.
