HIWIN EGH-45-CA-ZO-C Linear Guide Slider Block — 1 Piece

HIWIN · EGH Series · Flanged Linear Block · In stock

The EGH-45-CA-ZO-C is a low-profile, flanged linear guide slider block from HIWIN, a Taiwan-headquartered linear motion specialist recognized across Asian, European and North American machine shops as a premium alternative to THK, NSK, IKO and Bosch Rexroth. At 45 mm rail width, this EGH-series carriage is the mid-size workhorse of the family, designed for medium-load precision motion in spaces where a taller HGH or HGW block simply will not fit. KOEED stocks the full HIWIN EGH lineup from EGH15 through EGH45, plus mating EGR rails, to support CNC builders, automation integrators and MRO teams running Fanuc, Mitsubishi and Siemens-controlled machinery.

Key Specifications

Datasheet Highlights

• Low-profile flanged form factor: EGH-series blocks are roughly 30% shorter than the equivalent HGH/HGW block, making them the go-to choice when the Y-axis envelope is constrained by spindle clearance, gantry height or a downstream tool changer.
• Four-row gothic-arc groove design: The -CA long-body geometry distributes load over a larger contact footprint, raising moment capacity (pitch, yaw and roll) compared to the shorter -SA block of the same rail size.
• Self-aligning capability: The ball-return geometry tolerates minor mounting-surface parallelism errors, reducing the precision-machining burden on the machine builder when retrofitting older cast-iron frames.
• -ZO standard preload: Eliminates internal clearance while keeping rolling friction low — the default choice for CNC feed axes and pick-and-place gantries. For higher-stiffness applications (heavy cutting, large-radius milling), -Z1 light preload or -Z3 heavy preload variants are available on request.
• -C standard accuracy class: Suitable for general machine-tool, automation and 3D-printer applications. HIWIN also offers -H high and -P precision grades for grinding machines, inspection equipment and semiconductor handlers — send your spec sheet to Moritta@KOEED.COM for a matched quote.
• Drop-in rail compatibility: Mates directly with HIWIN EGR-45 rail (sold by the meter or cut to length). Most rail blocks across HIWIN EGH, HGH and HGW families are dimensionally interchangeable with the THK HSR, NSK LH and Bosch Rexroth R1622 series, simplifying legacy retrofits.

Typical Applications

• CNC machining centers — X/Y/Z feed axes on vertical machining centers, knee mills and small horizontal boring machines, particularly retrofit of older Fanuc 0i-MD or Mitsubishi M64-controlled lathes.
• Automation gantries and pick-and-place modules — the low-profile flange fits inside aluminum-extrusion frames where an HGH block would intrude on the cable carrier or the vacuum manifold.
• Semiconductor wafer-handling equipment — EGH-45CA paired with EGR-45 rail is a common XY-stage choice for front-end inspection and probing stations where cleanliness and stiffness matter equally.
• 3D printer and large-format additive manufacturing gantries — preferred over cheaper unbranded HGH15/20 carriages when running production volumes that demand repeatable positioning.
• Industrial 3D printers, laser cutting beds and PCB drilling/routing machines — any application needing 45 mm rail width with medium load in a low-clearance envelope.
• MRO replacement of worn slides on existing machines — an EGH-45CA block will physically and dimensionally replace a worn THK HSR45 or NSK LH45 carriage in most installations.
• Packaging machinery, label applicators and pharmaceutical filling lines — clean, lubrication-friendly motion where -ZO preload eliminates the play that causes label skew.
