Editrice NMB miniature bearing lubrication exactly what are the specific time

Editrice NMB miniature bearing lubrication exactly what some specific role we all know that a lot of NMB miniature bearing with lubrication, whether the effect of oil or grease has its own advantages. The NMB miniature bearing lubrication how much effect? The author simply adjusted for everyone today hoping to bring help! 1, NMB miniature bearing oil seal, oil seal is contain oils and NMB portal of miniature bearing not polluted by the outside world, many industrial NMB miniature bearing using only the ball bearing cage, some are using a metal seal systems, some with automatic refueling system, and presents the fully open position, and bicycle usually can't use this bearing, otherwise only in oil depletion or later after the first cycle, which brought an end to life, and the metal seal NMB though miniature bearing can also be in a relatively long time to avoid contamination, and can play a role oil, but can't open it in again after filling or thoroughly clean, so also not suitable for bicycles, bicycle use miniature bearings NMB must choose to purchase with a rubber seal, the encapsulation of pollution prevention performance is good, oil retention time is long, and can be used in a long cycle, plastic seal pick, then change of the internal thoroughly clean and grease. 2, NMB miniature bearing lubrication rust resistance: use within the NMB miniature bearing grease have rust, antirust performance is mainly is to look at the fat soluble, grease by different viscosity and different materials, with different levels of capacity and antirust performance, generally speaking, poor consistency is big and fat soluble oil water proofing property is better, this oil even in palin cavity is filled with water, can also be formed in the steel surface layer can withstand oil film. Bike because of the low speed, the choice of grease can use viscosity is relatively a little high, but the water proofing property is extremely strong, because the bike in washing the car, rainy days, cross-country, are often dealing with water, this makes the water proofing property is very important, even slightly sticky oil, also won't affect under low rotate smoothly, and a surface formed the oxidative damage, but that the whole stripping process and the ageing process will be fast. 3, mechanical stability: NMB miniature bearing lubrication oil in high speed rotating always will soften, lead to leakage, when vibration, oil will be thrown from the roll on extrusion, and the oil soap structure will produce mechanical disintegration make grease was damaged, or even thrown NMB miniature bearing.
