Ball Bearing Background Ever since man began to need to move things, he has used round rollers to make the job easier. Probably the first rollers were sticks or logs, which were a big improvement over dragging things across the ground, but still pretty hard work.
Ball bearings Contact Bearings Used primarily in agricultural, chemical, utilities and manufacturing industries, angular contact bearings are designed to for high-speed use and where anti-friction characteristics are needed.
Materials used to construct angular contact bearings include stainless steel, ceramic, and brass. Materials for the bearings and cage assemblies are selected to enhance performance and corrosion resistance. We Can Locate Any Major Brand and Type of Bearings for sale, including single-row angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings.
The differences between the types of angular contact bearings is the types of seals and shields available to Ball bearings in lubrication without affecting the bearing's speed capacity. Cylindrical Roller Bearings This type of bearing is characterized by the use of cylinders instead of balls as the rolling mechanisms.
The advantage is their high radial load capacity and speed. Single row cylindrical roller bearings incorporate a single caged bearing and are available in a variety of configurations to meet specific requirements.
Double-row varieties are stronger and allow for increased radial capacities. Multi-row cylindrical roller bearings are constructed using four or eight roller rolls, and provide very high radial load capacities, but lag behind other models in thrust capacity.
These Bearings for sale are aimed at metal rolling industries. Flange Bearings Flange bearings are designed primarily to support a shaft running perpendicular to the mounting surface. A wide variety of sizes are offered to accommodate different shaft sizes.
Two-bolt flanges, available in typical wing-shapes or diamond configurations, normally have two mounting holes and are favored for their ease of adjustment. Three-bolt flanges are normally round and have three evenly spaced mounting holes.
Four-bolt flanges are typically square and provide a fourth mounting bolt hole. Each type of these bearings for sale is engineered to meet specific fit and load-bearing needs. Pillow Block Bearings Pillow block bearings incorporate a bearing into a specific type of housing and are generally sold as a single unit.
The outer ring is intended to be stationary, with only the inner ring actually moving. This type of bearing is well balanced and typically delivers long service cycles without a great deal of user maintenance.
Even if the blocks are slightly out of alignment, the design of these bearings for sale compensates effectively through the use of a spherical ball used in its construction.
While easy to use, pillow block bearings are intended primarily for lighter duty use in relatively clean environments. Tapered Roller Bearings There are situations calling for Tapered roller bearings.NMB miniature ball bearings, global manufacturing, high precision.
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 ().
