The Peer RA100 agricultural bearing unit is a critical component in many farming implements, from planters to combines. Its reliability directly impacts your productivity and profitability. This article focuses on three key strategies for maximizing the lifespan of your Peer RA100 units, moving beyond basic maintenance to offer practical advice gleaned from years of experience in the field. We’ll explore everything from proper installation techniques to proactive maintenance schedules, and delve into unique insights on extending bearing life in harsh environments. This article solves 3 problems related to maintenance, proactive care and installation.
The Peer RA100 is designed for demanding agricultural applications. It’s built to withstand heavy loads, constant vibrations, and exposure to abrasive contaminants like dirt, dust, and moisture. However, even the best-designed bearing will fail prematurely if not properly installed and maintained. Before diving into specific tips, let’s briefly review the RA100’s core features and typical applications.
What Are Common Applications for the RA100?
The Peer RA100 agricultural bearing unit finds use in a variety of agricultural equipment, including:
- Planters: Supporting row units and ensuring accurate seed placement.
- Combines: Supporting rotating components in the header and threshing units.
- Discs and Cultivators: Handling the stresses of tilling and soil preparation.
- Hay Balers: Supporting rotating elements in pickup and compression systems.
These applications expose the bearing to immense stress.
Proper installation is paramount to a long and trouble-free service life. Often overlooked details during installation can lead to premature failure, costing you time and money.
Proper Shaft and Housing Preparation
Before installing the bearing, meticulously inspect the shaft and housing. Ensure they are clean, free of burrs, and within the manufacturer’s specified tolerances. Any imperfections can cause misalignment and uneven load distribution, leading to accelerated wear. Use a micrometer to verify dimensions and a fine file or emery cloth to remove any burrs or sharp edges.
The Correct Mounting Procedure
Always follow the manufacturer’s recommended mounting procedure. Use the correct tools and apply the appropriate amount of force. Avoid hammering directly on the bearing races, as this can damage the internal components. Consider using an induction heater to expand the inner race for easier installation, especially in cold weather. If pressing the bearing into place, ensure the force is applied evenly across the entire surface.
The Unexpected Benefit of Initial Greasing
Even pre-greased bearings benefit from a supplemental application of high-quality grease before installation. This ensures that all internal components are adequately lubricated from the start. I’ve found that a lithium-complex grease with EP (extreme pressure) additives works exceptionally well in the RA100 application. It provides excellent protection against wear and corrosion.
Once installed, the RA100 bearing requires regular maintenance to ensure optimal performance. This goes beyond simply adding grease; it involves a holistic approach to preventative care.
Creating a Robust Greasing Schedule
Establish a consistent greasing schedule based on the equipment manufacturer’s recommendations and the operating conditions. In dusty or wet environments, more frequent greasing is essential. Don’t over-grease, though, as this can damage seals and force contaminants into the bearing. Use a grease gun with a pressure relief valve to prevent over-pressurization.
The Right Type of Grease Matters
Selecting the right grease is critical. Consider factors like operating temperature, load, speed, and environmental conditions. Synthetic greases generally offer superior performance compared to conventional mineral-oil-based greases, especially in extreme temperatures. Also, be sure the grease is compatible with the bearing’s seal material to prevent premature seal degradation.
Inspecting for Signs of Wear and Tear
Regularly inspect the bearing for signs of wear, such as excessive noise, vibration, or heat. A simple infrared thermometer can quickly identify overheating bearings. Also, check for grease leakage or discoloration, which can indicate seal damage or contamination. Addressing these issues early can prevent catastrophic failure and costly downtime.
Agricultural environments are inherently harsh, and the RA100 bearing is constantly exposed to contaminants. Taking steps to mitigate the impact of these environmental factors can significantly extend bearing life.
Implementing Effective Sealing Solutions
While the RA100 bearing is designed with seals, consider supplementing these with additional sealing solutions, especially in extremely dusty or muddy conditions. Adding external seals or shields can provide an extra layer of protection against contaminants. Regularly inspect seals for damage and replace them promptly when necessary.
Reducing Corrosion
Moisture and humidity can cause corrosion, which weakens the bearing components. Applying a rust preventative coating to exposed surfaces can help minimize corrosion. Also, store equipment in a dry environment when not in use.
Innovative Applications of Ceramic Hybrid Bearings
While a full replacement may not be cost-effective in every scenario, consider using ceramic hybrid bearings in critical applications where downtime is particularly expensive. Ceramic balls are harder, smoother, and less susceptible to corrosion than steel balls, leading to extended bearing life and reduced maintenance requirements. Though Peer is the manufacturer, these are drop in replacements from other companies.
These can also greatly improve performance in high speed and high temperature applications.
With over 15 years of experience in agricultural machinery maintenance and repair, I’ve worked extensively with Peer RA100 bearings in a variety of applications. I’ve seen firsthand the impact of proper installation and maintenance on bearing life. My expertise is grounded in practical experience, supplemented by continuous learning and a commitment to staying abreast of the latest advancements in bearing technology.
While much of the advice presented here is based on personal experience, it’s also supported by industry best practices and recommendations from reputable sources.

| Issue | Possible Cause | Solution |
|---|---|---|
| Excessive Noise | Contamination, lack of lubrication, bearing damage | Clean and re-grease the bearing; replace the bearing if damaged. |
| Overheating | Over-greasing, misalignment, excessive load | Reduce greasing frequency; check and correct alignment; reduce load if possible. |
| Grease Leakage | Seal damage, over-greasing, incompatible grease | Replace seals; reduce greasing frequency; switch to compatible grease. |
| Premature Failure | Improper installation, inadequate lubrication, environmental contamination, overload | Review installation procedures; implement a robust greasing schedule; improve sealing; reduce load or upgrade to larger bearing. |
