How much the right self-aligning roller bearing grease

Bearing - comfortable and durable Self-aligning roller bearing electricity department authors for you on July 14th, spherical roller bearing grease how much different right bearing grease injection rate, associated with spherical roller bearing size and model. Grease filling quantity along with the structure and the volume of fatliquoring parts is different, generally filled to capacity of 1/3 to 1/2 advisable, for bearing general filling amount to 1/3 to 2/3 of bearing cavity is advisable. Filling quantity too much will make bearing friction torque increases, grease for mixing hot metamorphism, aging and softening, and lead to leakage of grease. Fill the quantity too little or inadequate, dry friction and damage to the bearings will happen. High-speed bearing should be filled to a third or less, only for low or medium speed bearing, especially in the easy to pollution of the environment, in order to prevent external foreign body into the bearing, the bearing cavity full filled. Self-aligning roller bearing grease how much suitable sealed bearing greasing commonly 20% ~ 30%, open bearings on the 30% ~ 50%, low speed bearings can fill, high speed and a little less. Simple fat injection rate formula is as follows: G = 0. 005× D× B which G for oil amount, unit G; D of bearing outside diameter, the unit mm; B is bearing width, the unit mm. So, need to know your bearing model, draw the corresponding outer diameter and width, can probably fat injection rate calculation. 14, such as 6204 bearing outside diameter 47, width is about 3 fat injection rate. 29 g, according to the 400 g butter gun manually play about 0. 8 g to calculate, you need to play about 4 times. Also, suggest use the grease gun greasing don't need to calculate the number of times, a simple method is filling the new bearing grease the old fat out top clean can, generally see fatliquoring hole new clean bearing grease.
