Be confident in your purchase, we're an Authorized Bijur Delomon dealer! Features: 10 Pack. Helps keep machines and components consistently lubricated which reduces the risk of bearing failure. Can be filled with any grease from NLGI #0 - 4. Refillable reusable. Activation is immediate. No switches, or activation accessories required. For: Lubrication of any equipment that: Is subject to vibration, shock, impact, high torque, or centrifugal forces. Has anti-friction oscillating, ball or roller bearings Has shielded bearings with seals Has bronze, oilite or open bearings Requires bearing flushing action Can be mounted in any position used in any hazardous areas. Dispensing Mechanism: Uses a spring, piston with metering rod, and piston seal ring. The design offers reliable, controlled lubrication through a simple, foolproof setup and durable, high-strength components. How it works: The meter rod?s graduated channels let the bearing draw grease only as needed. Venturi action releases lubricant only when the bearing is in motion. Prevents grease from packing into the bearing. Eliminates over-lubrication during planned machine downtime Operates at a low pressure of 1?5 psi to avoid damaging bearing seals. Grease flow stops automatically when the bearing stops. Springs: Assembled with the Medium (Silver) springs. Light (Blue), and heavy (Red) springs are included in the box. The extra heavy (Orange) spring is an optional add-on. The clear housing allows easy monitoring of grease levels. Easy instillation. Saves money: Nearly half of all bearing failures are due to improper lubrication such as over and under greasing. Protect Workers: LubeSite greasers often permit longer periods between greasing. Workers can avoid lubricating equipment while it's in operation can see lubricant levels from far away. NOTICE: Do not Overfill! Overfilling can cause over-pressure which can result in the top separating from base. This can cause serious head or eye injury. The Bijur Delimon LubeSite 302 Auto Greaser is a compact, refillable lubrication device built for use in applications involving vibration, shock, impact, and other dynamic forces. Its distinguishing feature is a lightweight anodized aluminum base, which provides enhanced durability and mounting stability in rough conditions. Packaged as a 10 Pack, it offers a 1 oz capacity and activates immediately without requiring switches or electrical components. This bearing greaser is compatible with a broad range of static and dynamic machinery containing shielded, sealed, or open bearings, including ball, roller, oscillating, bronze, and oilite types. It uses a spring-loaded piston with a metering rod and seal ring to dispense NLGI grade 0 to 4 non-separating grease at a steady 1?5 psi. The metering rod?s internal grooves regulate output so that grease flows only as needed, while the venturi mechanism ensures lubrication occurs exclusively during bearing motion, stopping when the machine halts. This system reduces grease waste and avoids bearing damage from over-packing. This grease feeder ships with a pre-installed medium (silver) spring, and includes both light (blue) and heavy (red) springs for custom flow rates. A clear dome allows visual monitoring of lubricant levels, and the Zerk fitting enables simple refilling. Suitable for mounting in any position, the unit performs well even in hazardous industrial environments. By reducing over- and under-greasing, this system helps extend equipment life and reduce service frequency, while also improving worker safety through hands-off monitoring and longer greasing intervals. Offering flexible application across industries and dynamic conditions, the Bijur Delimon LubeSite 302 Auto Greaser is a practical, durable solution for maintaining critical bearing lubrication.
