Positioning and Overview

 

This compact hydraulic motor is designed with a flange mounting interface that complies with SAE (Society of Automotive Engineers) Type A 2-bolt specifications. It is equipped with a precision 31.75 mm (1-1/4 inch) cylindrical output shaft as a core feature, and comes standard with 7/8-14 UNT O-ring face seal hydraulic ports. Meticulously optimized for drive scenarios in industrial and mobile machinery, this motor is ideal for applications with limited space layout, that require a simple and stable structure, and demand reliable rotational power output under medium and high-pressure operating conditions.

 

Core design advantages

 

 

1. Ultimate Space Utilization & Effortless Installation

◦ 2-Bolt Flange: Compared with flanges with four or more bolts, it occupies a minimal installation footprint with just two fastening points. Ideal for confined spaces such as equipment sidewalls and internal bulkheads, it dramatically streamlines the entire assembly and maintenance workflows.

2. Flexible & Reliable Power Output Interface

◦ 31.75mm Cylindrical Shaft: This standardized heavy-duty shaft design features superior flexural and torsional strength. Its smooth finish delivers unrivaled connection flexibility, enabling users to select the most cost-effective and practical custom connection solution based on the actual structural requirements of the driven end.◦ SAE ORB Port: Equipped with 7/8-14 UNT threaded ports and O-ring face seals, a premium leak-proof specification widely adopted in North American industrial hydraulic systems. Sealing performance is enhanced with increased face seal pressure; no Teflon tape or sealant is required during installation, thus preventing hydraulic system contamination from sealant residue.

3. Robust & Durable Industrial-Grade Construction

◦ The motor features a one-piece robust housing crafted from high-strength cast iron or steel, with optimized bearing arrangements. It is capable of withstanding moderate radial and axial loads, ensuring long-lasting reliable performance in typical industrial operating conditions with vibration and impact.

 

 

Application scenarios

 

Boasting a compact, robust build and standardized interfaces, this hydraulic motor serves as the ideal drive solution for the following applications:

  • Agricultural & Lawn Care MachineryPicker drive for large round balers, metering shaft drive for seeders, cutterhead drive for large mowers, and auxiliary drive for tractor front power take-off (PTO) systems.
  • Industrial Automation & Material HandlingDirect drive for heavy-duty conveyor line rollers, rotating spindle drive for packaging machinery, agitator shaft drive for mixing tanks, and multi-turn actuator drive for industrial valves.
  • Engineering & Construction EquipmentDistribution valve drive for small concrete pumps, vibration wheel drive (eccentric block drive) for vibratory rollers, and rotation mechanism drive for rock drilling equipment.
  • Specialized Vehicles & Sanitation EquipmentMain brush drive for road sweepers, auger snow collection roller drive for snow blowers, and push plate drive for sanitation waste compression trucks.
