Flanged roller linear guides are high-precision linear guide components that use cylindrical rollers as rolling elements and employ a flange mounting structure. They are widely used in heavy-duty, high-rigidity, and high-precision CNC machine tools, automation equipment, and other fields.
High Load Capacity: The rollers and guide rail have line contact, resulting in a larger contact area compared to the point contact of balls. This allows them to withstand greater radial, lateral, and reverse loads, making them suitable for heavy-duty applications.
High Rigidity and High Stability: A 45° contact angle design achieves equal load distribution in four directions, effectively resisting multi-directional moments and impacts, and improving the overall rigidity of the system.
High positioning accuracy: Repeat positioning accuracy can reach ±0.002mm. When used with ground guides (surface roughness Ra≤0.1μm), it meets the requirements of precision machining.
Low Friction, High Efficiency: Rolling friction reduces the coefficient of friction to only 1/50 of that of traditional sliding guides, significantly lowering the driving torque and resulting in substantial energy savings.
Long Lifespan and High Reliability: The roller structure exhibits only slight elastic deformation under heavy loads, resulting in minimal wear; combined with proper lubrication (such as grease lubrication), long-term high-precision operation can be achieved.
Easy Flange Installation: The flange structure supports screw fixing, allowing for compact installation space and making it suitable for space-constrained applications. Common flange types include round flanges, square flanges, and guide flanges.
Suitable for High-Speed and Reciprocating Motion: Low heat generation and fast response make it suitable for frequent start-stop operations or high-speed reciprocating motion, improving equipment efficiency by 20%~30%.
