1. Allowable static moment: the static moment with a certain direction and size. On the stress surface bearing the maximum force, the rolling surface and rolling body become 0.0002 times the radius of the rolling body.
2. Rated load: In work, the load that does not affect the work of the machine parts is usually in the load table of different models. This is one of the important parameters.
3. Service life: The linear guide rail is subjected to the force of rolling elements or other objects, which makes the surface fall off and affects the accuracy. Falling off is generally caused by rolling fatigue of materials. Improper use of linear guide rail, increased friction, corrosion and rust will reduce the service life of linear guide rail.
4. The linear guide rail has two types of basic rated load: one is to calculate the basic life; One is to define the maximum load in the static state.
5. Maximum load: If the linear guide rail is loaded with an object exceeding the maximum load, when it comes into contact with a rolling object, both of them will produce irreversible deformation. Deformation will cause the motion of linear guide rail to be unstable, which will seriously affect the accuracy.
6. Basic rated load: refers to the length of 50km when the same batch of guide rails operate under the same conditions. Under the condition of constant direction, the linear guide load can complete this movement by a large amount.
