HLG Hepco Linear Ball Guides

Product catalog summary
Introduction
The HLG range of recirculating ball guides is designed for smooth, low friction movement with high rigidity and load capacity. These guides feature a unique bleed lubrication system for easy re-greasing and are designed with four rows of balls at a 45º loading angle, providing equal vertical and horizontal load capacities. The X-style ball arrangement enhances tolerance to deviations in parallelism and height variation.
Block and Rail Options
HLG offers various block and rail options, including standard, compact, and spacer chain series, available in rectangular and flanged designs. These blocks are equipped with effective sealing to prevent dirt ingress and maximize grease retention.
Precision and Preload
HLG guides come in multiple precision and preload grades, such as Normal, High, Precision, and Ultra Precision, with preload options including Zero, Light, and Medium. These options ensure compatibility with ISO 12090-1 standards, allowing interchangeability with other systems.
Features and Benefits
The HLG series provides a comprehensive range of precision and preload grades, short lead times, competitive pricing, and compliance with ISO standards. The guides offer low deformation under external load, environmental protection through integral seals, and a bleed lubrication facility. A brake option is available for manual applications.
Technical Specifications
HLG blocks and rails are available in various sizes, with detailed specifications for dimensions, load ratings, and static moment capacities, suitable for heavy applications and offset loading.
Ordering and Installation
Ordering details include part numbers and configuration options. Installation data and rail joining details are provided to ensure proper setup and maintenance.
Conclusion
The HLG Linear Ball Guides offer a durable, high-performance solution for linear motion applications, with a range of options to meet specific requirements in various industries.
Basic Dynamic Load Rating
The basic dynamic load rating (C) is based on a constant, one-directional load allowing for 50km of linear travel, with 10% of guides potentially showing fatigue at this distance.
Factors Affecting System Life
Adjustments should be made for multiple blocks on the same rail and additional forces from vibration or impact. Other factors include excess load from inaccurate assembly, contamination, high-speed motion, damage to end plates, and lack of lubrication.
Variable Load Factor (fv)
This factor adjusts for additional forces from vibration or impact, with values ranging from 1.0 to 4.0 depending on speed and impact level.
Life Calculation
The fatigue life (L) is calculated using the formula L = C / (P * fc * fv), where P is the applied load.
Installation and Maintenance
Proper alignment during installation is crucial to avoid damage. Blocks should move freely on rails, and rough movement indicates contamination or assembly errors.
Dimensional Data
Tables provide installation dimensions for HLG and MLG block and rail assemblies, with specific measurements for different series and sizes.
Ordering Details
Part numbers for HLG and MLG blocks and rails include specifications for size, style, preload, and corrosion resistance. Options for accuracy grade and additional features like metal scraper seals are available.
Product Range
HepcoMotion offers a variety of products including slide systems, linear guides, and track systems, each with specific applications and configurations.

HLG Spacer Chain Rectangular Series HLG Spacer Chain Flanged Series Like the HLG...R series blocks, the new HLG Spacer Chain Rectangular Series blocks have the same features and benefits, but utilise a spacer chain between the balls to prevent them from colliding with each other when circulating. This allows for a more stable circulation of the balls, which reduces the loss of oil film when the system is in motion. With no collision, noise is also heavily reduced, especially at high speeds. Like the HLG...F series blocks, the new HLG Spacer Chain Flanged Series blocks have the same features and...

The HepcoMotion HLG brake provides a compact and simple method of locking an HLG bearing block into position. The brake is intended for manual locking of a stationary block, and can be supplied with a range of brake plates to suit most of the HLG bearing block options. When the brake is applied, the resulting clamping force does not impose any load upon the bearing block. Although tailored to suit Hepco HLG Linear Ball Guides, the brake is equally compatible with other ball guide systems, and is manufactured with stainless steel components*1. 4xM Customer Mounting Holes Dimensions for all sizes...
