The Stud (Part Number: 3201195142) is a precision-engineered fastening component exclusively designed for Hydraulic Rock Drills—critical equipment in mining, quarrying, construction, and tunneling projects where efficient and reliable rock penetration is essential.
Crafted from premium high-strength alloy steel (grade customized to meet OEM standards for hydraulic drill components), this stud undergoes a multi-stage heat treatment process, including quenching and tempering, to achieve a tensile strength of up to 1200 MPa, exceptional wear resistance, and corrosion protection against moisture, abrasive rock dust, and hydraulic fluid exposure. These properties make it uniquely suited to withstand the extreme operating conditions of hydraulic rock drilling, such as high-frequency vibration (up to 1500 Hz during drilling cycles), extreme axial and radial loads (often exceeding 50 tons), and temperature fluctuations ranging from -20°C to 150°C in underground or outdoor drilling environments.
Engineered to exact dimensional tolerances (±0.02mm for thread pitch and shaft diameter), the 3201195142 stud is a direct replacement for OEM parts in leading Hydraulic Rock Drill models (compatible with brands such as Atlas Copco, Sandvik, and Boart Longyear—customizable per client equipment specifications). Its primary function is to secure critical drill assemblies, including drill rod couplings, piston guide systems, hydraulic valve blocks, and feed mechanism components, preventing catastrophic component loosening or failure that could halt drilling operations and lead to costly downtime. The stud’s precision-machined threads (UNC/Metric options available) ensure a tight, vibration-resistant fit with mating nuts and brackets, while its chamfered ends facilitate easy installation and reduce the risk of cross-threading during maintenance—even in tight, hard-to-reach areas of the drill rig.
Beyond its mechanical performance, this hydraulic rock drill stud is manufactured in compliance with international industry standards, including ISO 898-1 (mechanical properties of fasteners) and API Spec 7-1 (drilling and production equipment), ensuring consistency and reliability across every unit. Each stud undergoes rigorous quality control testing, including ultrasonic flaw detection to eliminate internal defects, hardness testing (Rockwell C scale: 38-42 HRC), and torque load testing to verify its ability to maintain clamping force under sustained vibration. For added durability, select variants feature a zinc-plated or hot-dip galvanized finish, providing an extra layer of protection against rust and corrosion in humid or coastal mining/construction sites.
Whether deployed in surface mining operations (quarrying limestone, granite, or coal), underground tunneling projects, or foundation drilling for large-scale construction, the 3201195142 stud delivers long-lasting performance that minimizes unplanned maintenance and extends the service life of hydraulic rock drill systems. It is an indispensable spare part for mining contractors, construction firms, drill rig maintenance teams, and equipment rental companies that rely on Hydraulic Rock Drills for high-productivity, low-downtime operations. We offer bulk ordering options, custom packaging for safe transportation (anti-rust oil coating + waterproof wrapping), and technical support to ensure proper installation and compatibility with your specific drill model. Backed by a 12-month warranty against manufacturing defects, this stud represents a cost-effective investment in the reliability and efficiency of your hydraulic rock drilling equipment—eliminating the risks associated with low-quality, non-OEM fasteners that can lead to equipment damage, project delays, or even safety hazards in the field.
