HBU Series Cross-Tube Bushing Mount Double-Acting Welded Hydraulic Cylinder
The HBU Series is part of Apex Hydraulic's North American cross-reference welded hydraulic cylinder range. It features a cross-tube bushing mount design, double-acting operation, and rated working pressure up to 3,000 PSI. Available in bore diameters from 1.5 to 5.0 in and strokes from 4 to 48 in. Designed for mobile hydraulic applications requiring compact installation and reliable operation under vibration and impact.
Key Selling Points
- Cross-Tube Bushing Mount: Provides a stable pivot point and simplifies installation on loader arms and equipment frames, reducing downtime during replacement.
- Wide Bore and Stroke Range: 1.5–5.0 in bore and 4–48 in stroke accommodate various force and travel requirements without needing multiple cylinder sizes.
- Precision-Honed Steel Tube: Ensures low friction and consistent performance, contributing to smooth operation and extended seal life.
- Induction-Hardened Chrome Rod: 45–50 HRC core hardness and 0.001 in chrome thickness provide wear resistance and withstand harsh conditions.
- Threaded Serviceable Gland: Allows quick disassembly for maintenance, reducing repair time and total cost of ownership.
- Standard SAE O-Ring Ports: Compatible with common North American hydraulic fittings, simplifying integration into existing systems.

Models and Options
HBU Series is available in various bore, stroke, and rod combinations within the stated ranges. Customers can select bushing inside diameter, port options (SAE O-Ring as standard, NPT optional), and custom paint colors. Installation dimensions depend on the cross-reference model and approved production drawing.
Materials and Structure
The cylinder tube is precision-honed steel. The piston rod is induction-hardened steel with 45–50 HRC core hardness, hard chrome plated to 0.001 in thickness and final surface hardness of 69–71 HRC, passing 96-hour corrosion test per ASTM B117-07a. The piston is ductile iron. Heavy-duty welded steel construction provides a compact profile and excellent resistance to vibration and impact.
Applications
HBU Series is ideal for agricultural machinery, front-end loaders, material handling equipment, construction equipment, utility trailers, dump trailers, landscaping equipment, forestry equipment, and municipal equipment. It is commonly used in applications requiring lifting, tilting, pushing, and clamping operations in mobile hydraulic systems.
Customization
Apex Hydraulic offers customization of mounting dimensions, stroke lengths, hydraulic ports, paint colors, and packaging based on customer drawings or approved cross-reference models. Sealing systems are selected according to pressure, temperature, and application requirements.
