How to Increase the Life of Bearings

With the complex demands in food processing and production, safety, and quality, every component within food equipment is critical. Any machinery with moving parts will utilize bearings. Here are some tips to reduce wear issues and extend bearing life:

  1. Mount the bearing correctly after maintenance. Make sure shims are re-installed and that the shaft is correctly positioned, and make sure that the shaft and bearing housing have the correct tolerance. A bearing sitting loose on a shaft will cause significant damage to the shaft.
  2. Grease bearings according to manufacturer recommendations. A low RPM bearing on a mixer will not require grease as often than a grinder gearbox bearing. One grease schedule does not fit all bearings.
  3. Use the correct food-grade lubrication in the right quantity. Over-lubrication can blow out the grease seal, under lubricating can increase friction and cause failure. Seals protect bearing lubrication by keeping moisture, dust, and dirt out of the bearing; make sure seals are inspected and maintained properly.
  4. Check bearings regularly for excessive play and replace bad bearings before they cause damage to the equipment. Replacing a bearing is much less expensive than replacing a worn and grooved shaft.
  5. Choose the bearing type that will uphold to the food processing application.

    Standard bearings are steel ball bearings, mounted in a painted cast iron housing. Mepaco’s coating on standard bearings is a sealant with anti-corrosive benefits.

    In aggressive applications, food processors often choose polymer bearings. The polymer bearing has a moderate up-front investment – but the total cost of ownership is lower because it requires less maintenance when used in aggressive applications.

Quick Upgrades that Increase Production Right Now


1. Pull more out of your grinder

Ask your grinder experts about an upgrade kit to address a different plate configuration to increase throughput.  

If you do not have a level sensor, contact your controls partner to add controls to turn off the grinder before it runs dry. A continuous flow of meat product will keep the plates and blades lubricated - required for best performance.

Keep the pins, bushings, heads, and knives in well maintained condition.

2. Tune your system

Schedule an audit to tighten up your process. Look to remove 15 - 20 seconds from all inefficient processes. 

Consider VFD motors at different speeds to improve production flow.

3. Address small issues before they become a big downtime issue

With production at or near max or a lack of production staff, preventative maintenance may not be consistent. Operators need to allow time to address small maintenance issues. Rushing to close a safety grate that slams on the equipment causing welds to break, or not reporting wear of critical parts can lead to significant downtime.

If there is a repair needed on a piece of equipment, the best advice to ramp-up production is to have long-lead item parts on hand. Agitators that are custom fabricated can take up to eight weeks for delivery. Cylinders, motors, gearmotors and gearboxes are all long-lead items that can take up to 2 - 5 weeks for delivery.

Proper Operational Procedures Improves Dumper Performance

Depending on the complexity of the equipment and controls, there are a few options for production personnel to learn how to operate the equipment. The manual explains the operation of the equipment and its components. The customer can visit Apache for training and testing or contract with Mepaco Field Services for on-site training.

In one example, the production staff did not understand how to operate the HD3000 Dumper, causing the carriage to bind-up where cylinders weren't lifting in tandem. The issue was caused by incorrect operation.

Due to the operational configuration of the hydraulic cylinders, the HD300 dumper must be fully cycled (complete cylinder extension and retraction) each time it is used. The production staff was not fully retracting the dumper leaving the carriage 12 - 18" off the ground. This allowed the cylinders to start up unevenly and compounded if the staff did not fully extend the dumper. This caused the dumper carriage to misalign and bind against the dumper frame.

Once the carriage binds against the frame the only way to safely correct the situation is to lock out the hydraulic power unit, disconnect the hydraulic line from the overextended cylinder and allow the carriage to drift down until it is re-timed. Once the cylinders are re-timed the power unit can be operated to bring the carriage to the fully down position. Air will need to be bled from the cylinder that had the hydraulic lines removed.
