Overview of bearing mounting methods

 Roller Turn Rollor

 

Applications

This is a useful technique when driving small bearings with cylindrical bores onto shafts or into housings.

 

ii. Drive method

The thrust method is a hydraulic technique. Some of the important tools used in this technique are

Lock nut wrench

Hook wrenches

Hydraulic nuts and pumps

The hydraulic method is much more powerful compared to the mechanical method. If used improperly, hydraulic tools may remove radial clearance from bearings.

Applications

This is the preferred technique for driving medium to large bearings with tapered bores onto tapered seats. The method uses hydraulic tools.

 

III. Oil Injection Method

This oil forms a film between the two surfaces, thus reducing friction and making mounting easier. Note, however, that for this procedure, both the pipe and the recess should already be in place as part of the shaft design. If not, the grooves, feed channels and threaded connections must be machined into the shaft or sleeve before performing the oil filling.

Applications

This method also uses hydraulic tools to facilitate the mounting of medium and large size bearings with a tapered bore by a film of oil injected between the inner ring bore and its seat.

2. Thermal mounting

Hot mounting uses heat to expand the bearing, reducing the interference fit and allowing the bearing to slide easily onto its mating parts.

Let us look at the different methods of using heat to mount bearings.

Ise. Induction heater

Induction heaters are the most effective way to heat bearings for thermal mounting. The induction method requires the preparation of several tools.

Induction heater (of course!)

Heat-resistant gloves

Yoke

 

How does it work?

1. An electric current flows in the heater's coils, creating a magnetic field in the core.

2. This creates eddy currents in the bearings.

3. The bearing heats up due to the resistance of the bearing material to the eddy currents.

4. To eliminate the typical interference fit, the temperature difference between the bearing and the ambient temperature is approximately 90°C.

ii. Electric heating plates and heating cabinets

These devices are fairly easy to use. Before using the equipment to heat the bearing, set the preset temperature accordingly.

While ovens and hot plates can be used for batch heating of small bearings, they are usually inefficient and time consuming for heating larger bearings.

 

Overview of bearing mounting methods

The precise tools and procedures required to mount bearings vary by type, size, speed, application, and industry. Our team of experienced engineers are on hand to provide expert consultation and advice to help you install them properly to extend the efficient operation of your equipment.

Everything you should know about roller bearings

Roller bearings are crucial components in various machinery and equipment, serving the purpose of reducing friction and facilitating smooth rotational motion. This article addresses 10 common questions related to roller bearings, offering insightful answers to help you better understand their functionality and applications. 1. What Are Roller Bearings? Roller bearings are mechanical components designed to support radial and axial loads while allowing for smooth, low-friction rotation. They consist of cylindrical or  tapered roller bearings  arranged in a cage, which helps distribute the load evenly and reduce friction. Roller bearings are widely used in industries such as automotive, manufacturing, and aerospace due to their efficiency and durability. 2. How Do Roller Bearings Work? Roller bearings work by distributing the load over the rolling elements (rollers) rather than the entire surface, which reduces friction. When a load is applied, the rollers roll smoothly, minimizi...

Ball Bearings vs. Roller Bearings: Unraveling the Key Differences

  When it comes to understanding the mechanical components that keep our world in motion, bearings play a vital role. Whether you're a seasoned engineer or simply a curious individual looking to gain insights into the world of machinery, you may have wondered about the differences between two crucial types of bearings: ball bearings and roller bearings. In this comprehensive article, we delve into the intricacies of these mechanical marvels, shedding light on their unique features, applications, and advantages. Ball Bearings: The Precision Spheres Ball bearings, as the name suggests, consist of spherical balls that facilitate smooth rolling motion within a mechanical system. These bearings are renowned for their precision and ability to reduce friction, making them an integral part of countless machines and devices. The Anatomy of a Ball Bearing A ball bearing comprises several key components: Outer Ring: The outer ring, also known as the outer race, serves as the outermost part of...

Cylindrical Roller Bearing

  Cylindrical Roller Bearing Cylindrical Roller Bearing  with no ribs on the inner ring or outer ring, the inner ring and outer ring can move relative to the axial direction, so it can be used as a free end bearing. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can bear a certain degree of axial load in one direction. Generally, stamping steel cages or solid cages made of copper alloy cars are used. However, there is also a part of the use of polyamide forming cage. Features 1. The roller and the raceway are in line contact or repaired offline contact, with large radial bearing capacity, suitable for bearing heavy loads and impact loads. 2. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing. 3. The N type and NU type can move axially, can adapt to the change of the relative position of the shaft and the housing caused ...
