Product Description:
GR series linear guideway features a roller as the rolling element instead of steel balls.
The roller series offers super high rigidity and very high load capacities. GR series linear guide rail is designed with a 45-degree angle of Contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions. GR series has the high performance that provides high-precision manufacturing and achieves longer service life.
It features the same load in four directions (up/down/right/left) and self-aligning to absorb installation-error capability.
Linear slide rail as a type of rolling guide, run by the power between infinite scroll circulation steel ball in the slider and slippery course, along the slippery course load platform can easily do high precision linear movement.

Characteristics:
1. High precision: The manufacturing precision of the guide rail is extremely high, and can reach the precision of micron level, so that it can well maintain the linear motion and stability of the moving parts.
2. Good wear resistance: guide rail materials are usually made of high hardness, high toughness and wear-resistant materials, such as steel, copper, aluminum, titanium, etc., which can ensure the long-term service life of the guide rail.
3. Strong load resistance: the guide rail can withstand large axial and radial loads, and can meet the requirements of various specifications of machinery and equipment.
4. High rigidity: The rigidity of the guide rail is good, which can effectively resist external torque and bending force and ensure the stability of moving parts.
5. Smooth movement: The surface of the guide rail is specially treated, the friction coefficient is small, the movement is stable, and it is not easy to cause stagnation and friction loss.
