Price & Availability Contact us for pricing / 询价 This block features a square flange type with a low-profile design, making it suitable for installations where space is limited but high performance is required. The HGW45HC is manufactured with precision-ground raceways and high-grade bearing steel, ensuring smooth motion and long service life. This guide block is part of Hiwin's HG series, which is known for its four-ball contact design that offers excellent load capacity in all directions. The HGW45HC specifically has a compact structure that allows for high moment rigidity, making it ideal for applications involving overturning moments. It is available in various preload classes (ZF, Z0, ZA, ZB) and accuracy grades (C, H, P, SP, UP), allowing customization to meet specific application requirements. The HGW45HC is interchangeable with other Hiwin HG series blocks of the same size, and it can be used with HGR45 rails. It is commonly used in CNC machine tools, automated production lines, semiconductor equipment, and other precision machinery. With proper lubrication and maintenance, this guide block can provide reliable performance over an extended period, contributing to the overall efficiency and accuracy of the equipment. The Hiwin HGW45HC is a heavy-duty linear guide block from the HG series, designed to provide high rigidity and load capacity for demanding industrial applications. Basic Product Information Square flange type for high moment rigidity Interchangeable design for easy replacement Available in multiple accuracy grades (C, H, P, SP, UP) Low noise and smooth motion Lubrication fittings for easy maintenance High load capacity with four-ball contact design Technical Specifications Version & Model Difference The HGW45HC is part of the HG series, which includes different block types: HGW (square flange) and HGH (square low-profile). The 'C' suffix indicates a standard length block. Other versions like HGW45CC have a longer block for higher load capacity. The HGW45HC is the standard length version, suitable for most applications. Accuracy grades range from C (normal) to UP (ultra-precision), with corresponding preload classes ZF (zero clearance) to ZB (heavy preload). Application Scenarios Can the HGW45HC be used with rails from other brands? While it is technically possible to use rails from other brands with similar dimensions, it is not recommended. For optimal performance, accuracy, and load capacity, it is best to use the HGW45HC with Hiwin HGR45 rails. Mixing brands may lead to premature wear and reduced precision. What accuracy grades are available for the HGW45HC? The HGW45HC is available in accuracy grades C (normal), H (high), P (precision), SP (super precision), and UP (ultra-precision). The grade is indicated by a suffix in the model number, e.g., HGW45HC1H for grade H. Choose the grade based on your application's precision requirements. How often should the HGW45HC be lubricated? Lubrication frequency depends on operating conditions such as speed, load, and environment. Generally, it is recommended to lubricate every 100 km of travel or every 6 months, whichever comes first. Use high-quality lithium soap grease (e.g., Hiwin G01) and ensure the lubrication fittings are clean before applying grease. What is the difference between HGW45HC and HGW45CC? The HGW45HC is the standard length block, while the HGW45CC is a longer block. The longer block (CC) provides higher load capacity and rigidity due to increased contact area, but it requires more space. The HC version is suitable for most applications where space is limited.
