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 305 Auto Greaser is a refillable lubrication unit with a durable anodized aluminum base designed for use in environments where machinery is subject to vibration, high torque, or impact. Its 2 oz grease capacity and transparent dome support longer service intervals and visual monitoring without equipment shutdowns. Offered in a 10 Pack, the unit activates immediately upon installation without switches or additional components. This bearing greaser is suitable for equipment using anti-friction oscillating, ball, or roller bearings, whether shielded, sealed, or open. It also supports oilite and bronze bearings, as well as setups needing flushing action. It distributes NLGI grade 0 to 4 non-separating grease through a spring-loaded piston and metering rod that delivers lubricant only during motion. This venturi mechanism prevents grease from over-packing and stops flow automatically when movement ceases, minimizing downtime and protecting seals by maintaining a low pressure of 1?5 psi. The grease feeder includes pre-installed medium (silver) springs, with light (blue) and heavy (red) springs for adjustable output. A Zerk fitting allows easy refilling, and the clear housing enables users to check grease levels at a glance. With mounting flexibility and hazardous area compatibility, this model meets the needs of multiple industrial sectors. This system supports worker safety by extending greasing intervals and reducing the need for direct equipment access during operation. It also helps prevent costly damage caused by inconsistent lubrication. Designed for rigorous settings and offering straightforward installation, the Bijur Delimon LubeSite 305 Auto Greaser is a practical solution for maintaining bearing performance across a multitude of industrial environments.
