What Causes Failure in Combined Bearings and How Can It Be Prevented
Speaking of the heavy machinery business, the combined bearing, also termed a slewing bearing or a slew ring bearing, is the unsung hero enabling the smooth rotation of heavy infrastructure bodily through the entire 360 degrees of the circle. Although the heavy machinery like booms and cranes forms a recognizable part of heavy infrastructure, it is the concept of a slew ring bearing that enables the machinery to achieve the stability necessary for effective use. Without a superior means of bearing, any machinery would inevitably fail under the force it is expected to bear in the long or short term, perhaps within a span of merely months alone.
At Kavitsu Bearing, as one of the first Indian bearing manufacturers, we are building indigenous bearing products of superior class, comparable to what is currently prevalent worldwide. We are aware that in contemporary infrastructure development, selection of optimal bearing is like continuous management of stress on machinery.
What Are Combined Slewing Bearings?
These are bearings of large diameters and bear the onus of combined loads. Unlike any other bearing, which only has the capacity to bear only one kind of force at any given time, slewing bearings are “two-in-one” formations. These are meant for keeping machine failures at bay by being composed of materials resistant to extreme pressure and vibrations.
Generally, the critical functions of a high-performance combined bearing include:
- Managing Complex Loads: Balancing axial, radial, and tilting moment forces simultaneously.
- Facilitating Rotation: Providing for 360° rotation or restricted rotation of heavy machines.
- Precision Positioning: The gear teeth provide a means by which precision can be achieved. Precision is an essential component in tracking systems, like robots.
Primary Causes of Combined Bearing Failure
The first step towards increasing the cost efficiency and the lifespan of the entire device is to understand the reasons why these components fail. The main reasons why they fail are:
Primary Causes of Combined Bearing Failure
The first step towards increasing the cost efficiency and the lifespan of the entire device is to understand the reasons why these components fail. The main reasons why they fail are:
1. Improper Lubrication and Environmental Contain
Inadequate and substandard lubrication and alignment can cause “gritty” damages to the surrounding components of the machine.
- The Issue: Inadequate lubrication causes excessive friction and rubbing of the rolling elements and the bearings.
- The Impact: In salt water or “mud-rich” environments, failure to provide adequate lubrication or defective seals will allow corrosive materials to seep into the bearing foundations.
- Kavitsu Solution: Under routine maintenance, or when signs of “weeping” exist, seals and lubrication should be checked.
2. Overloading and Stress Concentration
The commonest causes for such failures include overloading the bearing.
- The Issue: Stressed Concentration of Exceeding Rated Capacity of a Bearing
- The Impact: This leads to metal fatigue, which might cause the component to fail.
- Kavitsu Solution: We use our “load-bearing firewall” approach, where our bearings distribute force over multiple points of contact.
3. Improper Installation
The slightest mistake in the initial system setup can affect the integrity of the entire system.
- The Issue: Improper installation is a major contributor to premature failures.
- The Impact: If it is not installed correctly, it may have “stiff” and “wobbly” movements, as seen in excavators or cranes.
- Kavitsu Solution: We offer customized solutions and consultation services to meet requirements of specialized industrial or defense needs.
How to Prevent Failure in Combined Bearings?
Prevention focuses on proactive engineering and regular maintenance.
1. Rigorous Inspection and Maintenance
- Regular Checks: Check the seals and lubrication at every routine service.
- Monitor Vibrations: Be aware of any abnormal vibrations, as our products are designed with the principles of de-escalation of vibration hazards.
- Grease leakage: Address any sign of “weeping” without fail, so that potential damage could be averted.
2. The Right Material and the Right Design
The material choice for your combined bearing is vital for the resistance to environmental stresses.
- Environmental Resistance: Advanced materials, capable of withstanding salt water and corrosive conditions in marine environments.
- Matching Load: Make sure the bearing is designed for operation under combined loads including axial, radial, and moment loads.
3. Utilizing Precision Geared Solutions
Precision slewing rings are considered the “gold standard” in robotic arms.
- Enhanced Control: Geared bearings, whether internal, external, or ungeared, offer enhanced precision required in tracking mechanisms.
- Operational Stability: High-quality slew bearings enable machines to instinctively respond to operator controls, promoting balance
