ZJBE Injectors for Automatic Lubrication Systems

ZJBE injectors are precision lubrication dosing devices designed to deliver specific volumes of lubricant to individual lubrication points within automatic lubrication systems. They help ensure that each bearing, slide, or pivot receives the right amount of oil or grease, improving reliability and reducing wear.

What Are ZJBE Injectors?

ZJBE injectors are mechanical metering devices used in centralized lubrication systems. They dispense a defined amount of lubricant each time the system cycles, based on system pressure and design. These injectors are often used in systems where consistent, repeatable dosing is critical.

Primary Use Cases

• Delivering measured lubricant volumes to individual lubrication points
• Protecting bearings, guides, sprockets, and other moving components
• Systems with multiple lubrication points from a single pump
• Applications where manual greasing is impractical or inconsistent

Who Uses ZJBE Injectors

• Maintenance and reliability teams
• OEM machine designers and builders
• Manufacturing and production facilities
• Facilities using automated lubrication to reduce downtime

When to Use ZJBE Injectors

• When precise lubricant dosing is required at each lubrication point
• In systems with multiple points fed from one central pump
• When consistent lubrication reduces wear and extends service life
• When eliminating manual lubrication improves safety and uptime

When ZJBE Injectors May Not Be the Right Choice

• In simple lubrication needs with only one or very few points
• Where lubricant volume varies significantly between points
• When a different metering method (e.g., progressive or divider blocks) suits system requirements better

How ZJBE Injectors Fit Into Lubrication Systems

ZJBE injectors are installed downstream of the lubrication pump and ahead of the tubing that feeds individual lubrication points. When the system pressurizes, each injector opens and dispenses its preconfigured volume of lubricant into the line, ensuring accurate delivery to the intended point.

Common Types & Configurations

• Single output ZJBE injectors – Provide a defined amount of lubricant to one point.
• Multi-output ZJBE injectors – Deliver to multiple points in a balanced configuration.
• Pressure-activated injectors – Open at defined pressure to control dosing.
• Grease and oil compatible models – Configured for specific lubricant types.

Common Mistakes and Misapplications

• Choosing injectors with incorrect output for the lubrication point
• Failing to match injector settings to system pressure range
• Installing injectors without considering tubing resistance and routing
• Using the wrong lubricant type for the injector model

Key Benefits

• Accurate, repeatable lubricant delivery
• Improved equipment life and reduced wear
• Balanced lubrication across multiple points
• Less lubricant waste and mess compared to manual greasing
• Reduced maintenance time and increased uptime

Frequently Asked Questions

What is a ZJBE injector?
A ZJBE injector is a metering device used in automatic lubrication systems to dispense precise lubricant volumes to individual points when the system cycles.

How do ZJBE injectors differ from dividers?
ZJBE injectors meter and deliver defined lubricant amounts, whereas dividers only split flow without metering specific volumes.

Can ZJBE injectors work with both oil and grease?
Yes — but you must select the correct model configured for the specific type and viscosity of lubricant you are using.
