Linear Rail Archives

Short Description Points

Type: Linear guide (1BA, round shaft)
Load: Primarily radial loads; limited axial and moment capacity
Cage: Polymer or metal retainer depending on model
Performance: Smooth, low-friction motion with good repeatability
Construction: Bearing housing with rolling elements + retainer; rides on hardened round shaft
Use cases: CNC axes, 3D printers, automation slides, gantries, robotics, inspection jigs
Note: Requires proper shaft hardness, alignment, and lubrication; avoid heavy side moments or unsupported heavy loads

Type: Linear guide block (EGR 15 WERB series)
Load: Supports radial and moderate moment loads during guided linear travel
Cage: Internal retainer guiding recirculating rolling elements (steel or polymer depending on model)
Performance: Smooth motion, low friction, accurate positioning when aligned correctly
Construction: Precision machined block body with recirculating ball path designed to run on EGR 15 linear rail
Use cases: CNC machines, 3D printers, automation equipment, gantries, robotics slides
Note: Must be used with matching EGR 15 rail, proper alignment and lubrication required for best performance.

Type: Linear guide block (MGN 12H series)
Load: Supports radial, reverse radial, and moderate moment loads during linear motion
Cage: Steel ball retainer with recirculating ball path
Performance: High precision guidance, low friction movement, stable positioning
Construction: Hardened steel carriage with internal recirculating ball bearings running on an MGN12 rail
Use cases: 3D printers, laser cutters, small CNC machines, automation slides, robotics motion stages
Note: Designed for use only with MGN12 rails; correct alignment and lubrication are required for best performance and durability.

Type: Linear guide rail (HGR series)
Load: Supports high radial and moment loads when paired with matching bearing blocks
Cage: Recirculating ball system with internal retainers inside the block
Performance: High rigidity, smooth motion, low friction, precise linear guidance
Construction: Hardened steel rail with precision ground raceways used with HGR20 bearing blocks
Use cases: CNC machines, automation gantries, robotics systems, laser machines, large motion platforms
Note: Requires precise mounting surface, correct block compatibility, and regular lubrication for best performance.

Type: Linear guide rail (HGR series)
Load: Designed to support radial, reverse radial, and moderate moment loads when paired with matching blocks
Cage: Recirculating ball system inside the bearing block (rail itself has no cage)
Performance: High precision linear motion with low friction and strong rigidity over long travel lengths
Construction: Precision ground hardened steel rail with mounting holes for rigid frame installation
Use cases: CNC machines, automation gantries, robotics tracks, material handling systems, precision sliding platforms
Note: Must be used with compatible HGR 25 bearing blocks and mounted on a flat, aligned surface for best accuracy and lifespan.

Type: Linear guide rail (HGR series)
Load: Supports high radial and lateral loads through matching carriage block
Cage: Rolling element retainer inside the carriage block (steel or polymer depending on block model)
Performance: High rigidity, precise linear guidance, smooth motion under heavy loads
Construction: Precision hardened steel rail with ground raceways used with recirculating ball carriage block
Use cases: CNC machines, gantry systems, industrial automation equipment, robotics, precision machine tools
Note: Requires compatible HGR45 carriage block, proper mounting alignment, and regular lubrication for optimal life and accuracy.
