What is conical bearing?
Conical bearings (tapered rollers bearings) are a type of rolling bearing. Their elements usually have the shape of cut cones that move on the raceway. These bearings carry complex loads, i.e. simultaneously occurring radial and axial loads. The tapered roller bearing consists of an outer ring and an inner ring.
What is a crowned bearing?
Crowned races have been proposed for crossed roller bearings. Crowning of the races is expected to reduce scuffing of the cylindrical rollers. Crowning of the races is expected to be especially beneficial in bearings made of polymers (instead of metals) to reduce weight.
How does a journal bearing work?
In a journal bearing, the shaft rotates inside a loose-fitting bearing shell of softer, often porous, bearing material. Lubricant, such as oil, grease or a low-friction compound like PTFE or graphite is used between the surfaces. The shell is sometimes split into two halves.
How many types of taper roller bearings are there?
Depending upon the contact angle, tapered roller bearings are divided into three types called the normal angle, medium angle, and steep angle. Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.
What are track rollers?
Track rollers—also referred to as idler rollers—are motion transmission components designed to work with all varieties of tracks. They see use in conveyor systems, cam drives, and a wide range of similar material handling systems.
What is the difference between radial and axial load?
Radial Load is defined as the maximum force that can be applied to the shaft in the radial direction (any direction perpendicular to the motor shaft axis). Axial Load is defined as the maximum force that can be applied to the shaft in the axial direction (in the same axis as or parallel to the motor shaft axis).
