KOYO cylindrical roller bearing installation measures to resolve the common problems

A, if asked KOYO bearing installed on the surface and places with iron filings, burr, dust and other foreign matter to enter, will make cylindrical roller bearing noise and vibration during operation, and even damage raceway and rolling body. So, before the installation of bearings, you must ensure that the installation surface and the environment clean. Second, the bearing must be cleaned before installed bearing surface coated with anti-rust oil, you must clean with clean petrol or kerosene carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Cleanliness of cylindrical roller bearing life and the influence of vibration noise is very big. But we especially want to remind you is: fully enclosed bearing not clean fuel. Three, the choice of the grease lubrication for work and life of KOYO bearing has extremely important impact, here a brief introduction to select the general principles of the grease to you. Grease made out of base oil, thickener and additive, different types and different type of same kind grease properties vary widely, allowing the rotation of the limit, when the choice is important to note. The performance of the grease is mainly composed of base oil, the basis of generally low viscosity oil is suitable for low temperature, high speed, high viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives. Four, grease add lubrication bearing, oil paint, the more the better, this is a common mistake. Cylindrical roller bearing and bearing indoor excessive grease will cause excessive oil mixing, resulting in a high temperature. KOYO bearing lubricant filling quantity to full of bearing internal space 1/2 ~ 1/3 advisable, high speed should be reduced to one-third. Cylindrical roller bearing damage state of two important reasons and solving measures, fault, damage status: fracture refers to the of raceway on the wheel rim or local part of the roller Angle are exerted impact or excessive load and a small part of the fracture. This is the very common one kind of damage. Everyone in use as far as possible attention. Reason: when installation is shocked; Too much load; Using bad fall, etc. Measures: to improve the installation method ( Adopt the hot charging, using the appropriate tool holder) ; Correct load conditions; Bearing installed, supporting to guard. This is the first. Skin: damage status: presents with slight wear dark side, dark surface by the surface of multiple deep down inside to 5 - Tiny cracks of 10 m, and on a larger scale slightly off ( The tiny stripping) 。 Reason: the lubricant is not appropriate; Foreign body into the lubricant inside; Lubricant bad cause rough surface; Matching rolling parts surface finish is not good. Measures: select lubricant; Improve sealing device; Improve the matching of rolling parts surface finish.
