A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
The ball bearing units are used in conveyor systems, food processing and packaging industry, agricultural industry, textile, construction and equipment industry.
Deep groove ball bearings
Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types
Single Row Deep Groove Ball Bearing
This bearing type is robust and requires less maintenance than other bearing types. Available, in a wide range of designs, sizes and variants.
Stainless Steel Deep Groove Ball Bearing
Corrosion resistant to moisture and other media, these bearings are ideal for harsh environments such as food and beverage, marine and agricultural industries.
Stainless Steel Deep Groove Ball Bearing with Filling Slots
Designed with filling slots to accommodate more balls, these bearings have a higher radial load carrying capacity than conventional bearings.
Double Row Deep Groove Ball Bearing
This double row design is a good alternative to single row deep groove ball bearing when higher load carrying capacity is needed.
Features and benefits
- Low friction and running temperatures, low noise and vibration
- High running speeds
- High quality and performance capabilities for your application
- Accommodate radial loads and axial loads in both directions
- Available with a variety of greases for most conditions, including food quality grease, high temperature grease and Solid Oil
- Increased reliability and provide long bearing and lubricant service life
Here are examples of applications in which Deep Groove Ball Bearings Mostly be used:
- Electric motors and generators
- Material handling
- Industrial transmissions
- Food and beverage
- Industrial pumps
- Industrial fans
- Two and three wheelers
- Cars and light trucks
Insert bearings (Y-bearings)
Insert bearings (HIND Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
Locking with an adapter sleeve
Locking with an eccentric locking collar
Locking with an interference fit
Locking with set (grub) screws
Features and benefits
- Quick and easy to mount
The different locking methods enable quick and easy mounting of insert bearings onto the shaft.
- Accommodate initial misalignment
The spherically shaped outside surface enables initial misalignment by tilting in the housing.
- Long service life
The different sealing solutions available provide a long service life for a wide variety of applications with high contamination levels.
- Reduced noise and vibration levels
Where high requirements on noise and vibration levels are important, Hind Bearing can provide the appropriate shaft locking method.
Here are examples of applications in which insert bearings Mostly be used:
- Agricultural machinery
- Construction machinery
- Food and beverage processing and packaging
- Conveyor systems
- Material handling systems
- Packaging systems
- Textile equipment
- Industrial fans
- Special machinery, e.g.car wash systems, gym equipment, go-karts
Angular contact ball bearings
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis
Single row angular contact ball bearings
Incorporating a large number of balls to give it a relatively high load carrying capacity, these bearings can accommodate axial loads in one direction only, are typically adjusted against a second bearing and have non-separable rings.
Double row angular contact ball bearings
With a design corresponding to two single row bearings arranged back-to-back, but where two single bearings take up too much axial space, they can accommodate radial and axial loads in either direction and tilting moments.
Four-point contact ball bearings
Designed to support axial loads in both directions and have a high load carrying capacity, these bearings can support a limited radial load for a given axial load, use less axial space than double row bearings and are separable.
Here are examples of applications in which angular contact ball bearings Mostly be used:
motors & generators
Trucks, trailers and buses
Self-Aligning Ball Bearings
Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
Thrust Ball Bearings
Our Thrust ball bearings are manufactured as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.In addition to the bearings presented in this section, Hind Bearings supplies thrust ball bearings for special application requirements.
Here are examples of applications in which thrust ball bearings Mostly be used:
Mining, mineral processing and cement
Angular contact thrust ball bearings
Hind Bearings Angular Contact Thrust Ball Bearings are separable, i.e. the washers and ball and cage assemblies can be mounted independently of each other. Although originally designed to support the rotary tables of drilling rigs, they are also suitable for other applications.
