Pillow Block Bearing
Bearings improve the working of the equipment and help to save energy and the machine parts altogether. Bearings perform their task silently, in harsh surroundings, concealed in apparatus where they are not visible. Yet, bearings are vital for the constant operation of machinery and for ensuring its regular performance.
Many types of bearings are in the market. Most selling bearings are cylindrical roller bearings, track roller bearing and wheel bearing.
Definition, Construction and Benefits of Bearings
- The word “bearing” includes the meaning of “to bear, to support, and to carry a load.” It states the fact that bearings upkeep and transmit the burden of rotating axles.
- The most basic bearings are the rolling bearings. They are made up of four basics parts and have a straightforward basic construction. The parts are:
- · Outer circular race: The big ring of the outer race
- · Inner circular race: The minor ring of the inner race
- · Spherical rolling elements: Many balls or rollers that are fixed in the space between the outer ring and inner ring
- · Containment cage: Used to contain the position of the rolling parts
- The primary purpose of bearings is mainly to decrease motorized friction. Dropping friction means:
- · Machine parts will run more smoothly
- · There will be very nominal frictional wear, lengthening the working life of the equipment
- · Stopping scratch burn, evading mechanical failure
- Bearings also aid to lower energy intake by reducing resistance and allowing the effective transmission of power. It is just one example of bearings being more environmentally friendly.

Support rollers (yoke-type rollers) are planned to run on all types of tracks. They are founded on a needle or tubular m bearings. The best class support rollers are heat resistant up to at least: –40 to +100 °C and a temperature range up to 140 °C supported for brief periods.
- Cam Followers
Cam followers (stud-type rollers) are manufactured to run on any tracks and be used in cam or conveyor drives. They are made on the either needle or tubular roller bearings. In its place of an inner race, they have a threaded solid stud or pin. Standard temperature range is –40 to +100 °C but can withstand up to 120 °C for short-term periods.
Cylindrical Roller Bearings
- What are Cylindrical Rollers
These are a particular type of roller bearings. In cylindrical roller bearings, the tubular rollers are in linear interaction with the raceways. They possess an excellent radial load volume and are appropriate for extraordinary speeds.
There are diverse types labelled as NJ, NUP, NU, N, NF (for one-row bearings), NNU, and NN (for twin-row bearings reliant on the schematics or lack of side ribs). The outer and inner raceways of all of the above types are detachable.
- Choice Concerns for Cylindrical Rollers Bearings
- Free End Bearings
Some cylindrical roller bearings have no spokes on either the inner or outer raceways so that the rings can rotate axially relative to each other. These can be employed as free-end bearings.
- Fixed End Bearings
Types NN, N, NU, and NNU are appropriate as open-end bearings. Variants NJ and NF can withstand partial axial loads in one way. Other varieties such as NH and NUP can be used as static-end bearings.
- NH-Type Cylindrical Roller Bearings
