Description
Product Overview
The LUBE USA 185001 HSA-02 standard metering unit is a precision flow control valve used in centralized lubrication systems. It regulates oil delivery to individual lubrication points, ensuring consistent and balanced lubrication throughout the machine.
This unit is designed for single-line resistance (SLR) systems with intermittent (cyclic) oil delivery and features standard (inch) threads for compatibility with inch-based systems.
Applications
- Centralized lubrication systems
- CNC machines and machining centers
- Bearings, slides, and moving components
- Lubrication points requiring low oil flow
π Metering units are resistance-type valves used to provide precise lubrication to each point in intermittent systems
Key Features
- Low-flow design (HSA-02 = small output)
- Standard (inch) thread configuration
- Controls oil delivery to individual lubrication points
- Designed for intermittent (cyclic) lubrication systems
- Compact size (~25mm length)
- Compatible with 4mm (5/32β) tubing
- Durable construction for industrial environments
Why This Part Matters
Not all lubrication points require large amounts of oil.
Without proper flow control:
- Small components may be over-lubricated
- Oil waste increases
- System balance is lost
This metering unit ensures low-demand points receive the correct amount of oil, improving efficiency and extending equipment life.
When to Use This Metering Unit
- When a lubrication point requires low oil flow
- When replacing worn or clogged metering units
- When balancing lubrication across multiple points
- When working with inch-based lubrication systems
