How to Correctly Mount and Dismount Bearings

 


Mounting and Dismounting of Bearings is an essential procedure that involves specific tools and techniques needed to correctly install and remove bearings.

Proper mounting of bearings is essential. Using the wrong techniques can significantly reduce your bearing’s service life, leading to bearing damage and failure, costing more time and money through unplanned downtime and replacing the bearing.

How to Mount Bearings correctly?

Mounting a bearing is a critical stage of the bearing life cycle. Using specialized tools maximises the chances of success and the bearing’s service life. The following process can be followed to mount bearings correctly.

  • Clean the Shaft and Housing - Before mounting a bearing, clean the shaft and housing with a solvent and clean cloth.
  • Apply Lubricant - Apply a thin layer of lubricant to the shaft and housing, ensuring the lubricant is evenly distributed.
  • Check Fit - Verify that the bearing and shaft/housing are the correct fit by measuring the inner and outer diameters of the bearing and the shaft/housing. Check the tolerance value against specifications.
  • Install Bearing - Position the bearing onto the shaft or in the housing, ensuring it is seated perfectly. Avoid hammering the bearing onto the shaft/ housing.
  • Apply Axial Load - Apply a slight axial force to the bearing to ensure it is properly seated.
  • Secure Bearing - Secure the bearing by tightening the locking device as per the manufacturer’s instructions.

How to Dismount Bearings correctly?

Every bearing has a service life that eventually comes to an end and the bearing needs to be replaced. If the bearing is not removed correctly, it could damage the housing, shaft or machinery, creating even more cost. The following process can be followed to dismount the bearings correctly.

  • Prepare Tools - Before dismounting the bearing, ensure you have the appropriate tools such as a puller or press.
  • Remove Locking Device - Take out any securing devices such as snap rings, locking nuts and set screws that secure the bearing in its position.
  • Apply Pulling Force - Apply pulling force using a suitable puller designed for the specific size and type of bearing to safely remove it.
  • Inspect Bearing - Examine the bearings thoroughly for indications of wear and damage, focusing on the raceway, rolling elements and cage to detect  signs of deterioration or wear.
  • Clean Shaft and Housing - Thoroughly clean the shaft and housing using a solvent and a clean cloth to ensure they are free from contaminants and debris. 
  • Install New Bearing - Install a new bearing following the steps of bearing mounting.

It is crucial to follow these simple instructions and safety guidelines when mounting and dismounting bearings to prevent damage to the bearing.

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...
