SKU: NXB-GEN-731-004 | Version: 1.0 | Brand: NexBot Robotics
NexBot Robotics 731-004 Joint Grease Cartridge (NXB-GEN-731-004) is a joint grease used in industrial robotics equipment where category-specific fit, electrical or mechanical compatibility, and predictable serviceability are important to buyers. The product should be understood as the exact component named by its category path, not as a complete robot or a generic service item. It supports installation, replacement, and maintenance workflows in robotic production cells by giving procurement and maintenance teams a clearly defined part class, relevant engineering specifications, and application context that matches the actual hardware being purchased.
The NexBot Robotics 731-004 Joint Grease Cartridge is identifiable by its SKU NXB-GEN-731-004 printed on the label. The label also includes the batch number and expiration date, which should be verified before use.
This grease cartridge is specifically formulated for NexBot Robotics equipment. Always cross-reference the SKU NXB-GEN-731-004 with the official maintenance manual for your specific robot model to ensure compatibility and prevent equipment damage.
Store cartridges upright in their original packaging between 0°C and 40°C (32°F and 104°F). Avoid dropping the HDPE cartridge, as impacts can damage the seals and lead to leaks or dispensing issues.
The re-lubrication interval depends on the robot's duty cycle, operating environment, and axis load. Refer to the specific robot's maintenance schedule for precise frequency guidelines for each joint.
When applying grease, the goal is to displace the old, degraded grease with new lubricant. Apply new grease until a small, consistent bead of the old grease is visibly purged from the joint's seals. This ensures the entire joint is filled with fresh lubricant.
Visually inspect the purged grease. If it appears watery, discolored, or contains metallic particles, it may indicate a deeper mechanical issue or excessive contamination requiring further investigation beyond simple re-lubrication.
While under-lubrication is harmful, over-greasing can also cause problems by blowing out seals and creating a mess that attracts contaminants. Stop applying pressure as soon as clean grease is purged from the seals.
Once a cartridge is empty, it should be disposed of in accordance with local, state, and federal environmental regulations. Even an 'empty' cartridge contains residual grease and should not be disposed of in standard municipal waste.
| Interval | Task | Notes |
|---|---|---|
| Weekly | Check inventory levels of NXB-GEN-731-004 cartridges to ensure adequate stock for scheduled maintenance. | Reorder when stock reaches the pre-determined minimum level. |
| Monthly | Inspect all stored grease cartridges for any signs of physical damage, such as cracks in the HDPE body, or leakage around the seals. | Quarantine and properly dispose of any damaged cartridges. |
| Quarterly | Rotate stock using the First-In, First-Out (FIFO) method to ensure older cartridges are used before they expire. | Move cartridges with the earliest expiration dates to the front of the storage shelf. |
| Annually | Conduct a full inventory audit and check the expiration dates on all stored NXB-GEN-731-004 cartridges. | Any cartridges that are past their expiration date should be removed from service stock and disposed of properly. |
| As Needed | Clean and inspect grease guns used for application. Ensure couplers and nozzles are free from hardened grease and contaminants. | A clean tool prevents contamination of the robot joint during lubrication. |
| Symptom | Possible Cause | Solution |
|---|---|---|
| Grease will not dispense from the grease gun. | The grease fitting on the robot is clogged, or there is an air lock in the grease gun. | Clean the grease fitting thoroughly. Re-prime the grease gun to purge any trapped air. |
| The cartridge does not fit into the grease gun. | The grease gun is not designed for a 235 x 54 mm cartridge. | Verify the grease gun's specifications. Use only NexBot-approved or compatible grease guns. |
| Grease is leaking from the back (plunger end) of the cartridge. | The cartridge's plunger seal is damaged or the grease gun's plunger is misaligned. | Replace the NXB-GEN-731-004 cartridge with a new one. Inspect the grease gun for damage. |
| Robot joint remains noisy or hot after lubrication. | Insufficient grease was applied, the wrong grease type was used, or there is an underlying mechanical failure. | Re-apply grease, ensuring old grease is purged. Confirm NXB-GEN-731-004 is the correct SKU. If the issue persists, schedule a mechanical inspection. |
| Grease appears to have separated (oil is leaking from the nozzle). | The cartridge was stored improperly (e.g., high heat) or is past its expiration date. | Discard the cartridge immediately. Use a new, in-date cartridge from properly managed stock. |
| The grease gun coupler will not attach to the fitting. | The grease fitting is damaged, or the coupler is worn out or the wrong size. | Inspect and, if necessary, replace the grease fitting on the robot. Inspect and replace the grease gun coupler if it is worn. |
| Excessive amount of grease is required to see any purge. | A seal in the joint has failed completely. | Stop applying grease. This indicates a mechanical failure that requires immediate inspection and repair by a qualified technician. |
