Maintenance Free Spherical Bearings Manufacturers in India

Terms including spherical bearings, ball bushings, spherical ball bushing bearings, and spherical plane bearings indicate 
one and the same kind of bearings. 
These components are designed to permit angular rotation about a center point in two statistically unrelated directions.

A rotating shaft is supported by these bearings inside the hole of their inner ring, which moves rotationally and at an angle. 
With the introduction of the concept of maintenance free bearings, the emergence of several maintenance free spherical bearings manufacturers in India is witnessed.

Spherical bearings- their design

These bearings are made up of an inner ring, an outer ring, and a clutch that grasps the inner ring inside the outer ring in the axial direction alone. 
 The outer surface of the inner ring and the inner surface of the outer ring are spherical. 
These surfaces slide against each other, with a lubricant, without a lubricant, or with the help of a rolling component such as several ball-bearings.

Spherical bearings- their applications

Applications that need to incorporate alignment movements between housing and shaft, and those that need recurrent titling, 
sewing or oscillating movements at relatively slow sliding speeds make use of spherical bearings. 
That is, spherical bearings are solutions used when the application needs the rectification of shaft misalignment. 
Therefore, these are used in heavy machinery, car suspensions, drive shafts, robotics, sewing machines, engines, etc.

Spherical bearings- types

There are a variety of spherical bearings available in the market to suit their usage in applications.
 Common spherical bearing types include spherical roller bearings, spherical ball bearings spherical rod ends, and spherical plain bearings.

Spherical Roller Bearings (also known as self-aligning double-row roller bearings) are 
used when the application requires the rectification of severe misalignments due to mounting or shaft deflection. 
Spherical Plain Bearings (also referred to as ball bushings, spherical ball bushing bearings, and spherical plane bearings) are used
 when the application needs the accommodation of misalignments between housing and shaft.

Spherical Ball Bearings (also referred to as self-aligning double-row ball bearings) are used when the application needs the
 accommodation of severe misalignments due to other causes.

Maintenance free spherical bearings

Spherical bearings that do not require lubrication are referred to as maintenance free spherical bearings. 
These are used in applications where the bearing has to operate under inadequate lubrication or completely without it.

Maintenance free spherical bearings manufacturers in India like Igus design and produce these components using a variety of material configurations like 
steel-on-PTFE composite material, steel-on-PTFE fibre, steel-on-Copper alloys, steel-on-PTFE plastic, etc.

Each of these combinations offer different advantages. For instances,
 the Steel-on-PTFE plastic bearings offer excellent weatherability (so, suits outdoor applications), 
the Steel-on-PTFE plastic has the lightest load capacity, Steel-on- PTFE composite material has a medium load capacity, and the Steel-on-PTFE 
fabric bearing has a dynamic load support capability.

Maintenance-free bearings- meritsEliminates the need for oiling the grooves and holes.
Dramatically lowers or entirely eliminates lubrication expenses, and thereby reduces the machinery’s operational costs.
Reduces the bearing maintenance expenses 
Provides for the cost reduction and simplification of mechanical devices.Contributes to environmental protection 
because of eliminating oiling requirements

Maintenance-free bearings- working principle

In the initial phases of its operation, a little amount of material from the maintenance-free bearings gets transferred
 from its outer layer to the machinery’s moving parts. 
This material forms a layer there, and acts as a solid lubricating film.

Among the maintenance free spherical bearings manufacturers in India, Igus is a leading firm. This German company with its Indian subsidiary based in Bangalore
, Karnataka, manufactures and distributes  machinery’s moving components including bearings,
 e-chains or drag chains, robotic components, bar stocks, cables, cable hoses, linear guides, cable carriers, etc.
