guide rail/linear guide 1.Finite element analysis is utilized to optimize the design of raceway cross-section, to acquire a larger rated load and rigidity. 2.. The four-direction equivalent load design enables our straight line guide to bear the equivalent load from up and down, left and right. 3. Preload can be imposed on the linear guide to improve its rigidity. 4. Strict process control is adopted in the production of straight line guide. The slide block is designed with a retainer which can prevent the rolling elements from sliding, so some slide blocks are interchangeable. 5. The lubricating of our straight line guide is quite simple. Lubricating nipple can be horizontally or laterally mounted on the slide block and grease can be jetted regularly by oil gun. Also, you can use special oil pipe joint to connect the oil pipe and utilize automatic oil feed machine to supply oil. 6. Numerical control management is applied thoroughly in the production of the linear guide to minimize the human error, thus ensuring the stability of quality.
