Pivot Assembly for Hydraulic Tilt Mechanisms

Product Specifications

Technical details and manufacturing context for Pivot Assembly

Definition

The pivot assembly is a critical component of the hydraulic tilt mechanism that serves as the rotational joint or fulcrum point. It enables the controlled tilting motion by providing a secure, low-friction bearing surface around which other components rotate. This assembly typically consists of a central shaft, bearings, housing, and mounting hardware, designed to withstand significant mechanical loads while maintaining precise alignment and smooth operation. The pivot assembly is used in machinery and equipment manufacturing, specifically in applications requiring controlled angular positioning. It is designed to operate within a tilt angle range of -15 to +15 degrees, with a rated load capacity of 50 to 200 kN at rated pressure. The operating pressure range is 1.0 to 1.6 MPa, and the maximum continuous rotational speed is 0 to 30 r/min. The assembly is rated for operating temperatures from -40 to 85 degrees Celsius, with a wider non-operating range. It uses a deep groove ball bearing type 6205 per ISO 15, and the seal material is nitrile rubber (NBR) per ASTM D2000 for hydraulic oil compatibility. The IP rating is IP65 per IEC 60529, indicating dust-tight and protection against water jets. The weight ranges from 5 to 15 kg, depending on size and material. Materials on file include alloy steel and bronze bearing material. For any specific application, it is essential to verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges for directory purposes.

Working Principle

The pivot assembly functions as a rotational joint that transfers hydraulic force into angular motion. When hydraulic pressure is applied to the tilt mechanism, the force is transmitted through the pivot point, allowing one section of the equipment to rotate relative to another. The assembly minimizes friction through precision bearings while maintaining structural integrity under load. The bearing type 6205 and seal material NBR are selected to ensure smooth operation and compatibility with hydraulic fluids. The assembly is designed to operate within specified pressure, speed, and temperature ranges, and its performance must be verified for the actual model and application.

Frequently Asked Questions

What is the function of a pivot assembly in a hydraulic tilt mechanism?

The pivot assembly provides a rotational connection point, allowing controlled angular movement of equipment sections. It transfers hydraulic force into angular motion, enabling tilting.

What are the key specifications to verify for a pivot assembly?

Key specifications include rated load capacity, operating pressure, tilt angle range, rotational speed, operating temperature, bearing type, seal material, IP rating, and weight. Always confirm these with the manufacturer for your specific model.

What materials are commonly used in pivot assemblies?

Common materials include alloy steel for structural components and bronze for bearing surfaces. The seal material is typically nitrile rubber (NBR) for hydraulic oil compatibility.

How should I verify the standards compliance of a pivot assembly?

Standards such as ISO 15 for bearings, ASTM D2000 for seal material, and IEC 60529 for IP rating are references. Verify actual compliance with the manufacturer or supplier.
