How to Safely Remove Bearing Seals and Shields Without Bearing Damage

 


Bearing seals and shields play a crucial role in protecting your bearings from dust and other contaminants. Sealed bearings are particularly essential in environments where contaminants are prevalent, as they provide an extremely tight seal that prevents contaminants from damaging or entering the bearing. Shields on the other hand, are used in environments where contaminants are present but moisture isn’t a concern.

How to safely remove a bearing seal

To remove a bearing seal, it is important to have correct tools on hand. A bearing seal removal tool that is thin enough to slide under the seal’s edge is essential. Begin by tracing the tool around the inside of the bearing until you locate the outer race. Then, gently slip the tool underneath the seal’s edge and pry it loose, taking care not to deform or break the seal or damage the bearing. This method allows you to access the cage and rolling elements inside the bearing and replace the undamaged seal afterward without compromising the bearing’s functionality.

How to safely remove a bearing shield

Removing a bearing seal also requires a specialised bearing shield removal tool. The method for removing shields varies depending on whether the shield is attached with a C-clip or is fixed.

How to safely remove a bearing shield attached with a C-clip

If your bearing shield is attached with a c-clip, you must first remove the clip before taking off the shield. Use a bearing shield removal tool to find the end of the C-clip by tracing around the inside edge of the outer race. Carefully pry out the clip, ensuring you do not damage the bearing race. Once the clip is removed, use the same tool to gently pry the shield out of the bearing. 

Removing a Fixed Bearing Shield

Removing a fixed shield from a bearing without damaging the shield is generally not possible, and the shield cannot be reused once removed. However, you can remove the shield without causing damage to the bearing, allowing access for maintenance. To remove a fixed bearing shield, use a sharp tool to pierce a small hole in the shield, then leverage the shield out of the bearing with the same tool.

Importance of Proper Seal and Shield Removal

Proper removal of bearing seals and shields is vital for maintaining bearing integrity and functionality. Damaging a bearing seal during removal compromises its ability to retain lubrication and prevent contamination, potentially necessitating the purchase of a new bearing, which increases the operating cost and maintenance time. In some applications, being able to remove a bearing seal without damaging it allows for reuse, providing significant benefits.

Schaeffler’s Arcanol: Elevating Bearing Performance with Advanced Lubrication

Image
  Choosing the correct lubricant is essential in ensuring that rolling bearings and linear units can achieve the desired performance and service life. Schaeffler's Arcanol lubricating greases undergo rigorous quality tests before supply. The quality of each batch is thoroughly tested and accounted for. In Schaeffler’s own analytical laboratory, the Arcanol lubricating greases are checked for their chemical and physical properties following strict guidelines to ensure high product quality. Lubricants Schaeffler’s lubricants offer significant benefits, enhancing the running behaviour of bearings and extending the life and operational reliability of the bearing arrangement. The lubricant range is graduated in such a way that it can be used in almost all areas of applications. This is evident as they can withstand various operating conditions and are suitable for all rolling bearings due to their completion of different testing procedures. In 2015, Schaeffler conducted over 50,000 hou...

The Role of Bearings in the Aviation Industry

Image
  Though small in size, bearings are the backbone of many industries that involve rotary machines and equipment. The aviation industry is no exception. However, this industry demands bearings that can handle extreme heat and immense pressures. They should be able to operate efficiently in corrosive environments. In this blog, we look at a few important applications of bearings in this aviation industry. Key Applications of Bearings in Aviation Bearings offer frictionless, smooth rotational, and linear motion between moving parts in the aviation sector. Commonly, in aircraft components, they are used in engines, flight control systems, and auxiliary power units. Flight Control Bearings Control bearings are specially designed to ensure smooth and responsive aircraft maneuvering. But how do these bearings help? Basically, they minimize friction and enable precise movement of control surfaces like ailerons, elevators, and rudders. For example, flight control linkages rely on spherical ...

Types of Main Bearings Used in Marine Industry

Image
  Lead Bronze, Bi-Metal, and Tri-Metal bearings: These three types of bearings play a huge role in the marine industry. They are utilised to support rotating shafts and reduce friction to ensure smooth rotations. These bearings come with distinct benefits such as high load-bearing capacity, wear and corrosion resistance. Let us explore what these three bearings are made of, how many layers they have, and what they are used for. Lead Bronze Bearing Flash layer: This topmost layer is composed of tin and lead. It is 0.035mm thick. This layer’s job is to protect the bearing from getting corroded and dust when not being used. It flashes off when a bearing is running. Nickle Barrier: This 0.02mm thick layer - made of nickel - helps prevent corrosion and avoid diffusion of tin into bearing metal. Lead Bronze: The third layer comes with an anti-seizing property. It is made of lead bronze. This layer is great at preventing parts from sticking together. In the setup, it is the main part th...
