Flanged mounted bearings are used when the axis of the shaft is perpendicular to the bearing mounting surface

Bolted roller bearings come with pre-assembled back-to-back sealed tapered roller bearings and seals. Designed to enhance equipment performance with industry-leading premium tapered roller bearings. The housing is ASTM A48 Grade 30 cast iron with an electrodeposited coating for better corrosion resistance than industry standard powder coatings. Mounted bearings and mounted ball bearing units provide much needed support and stability. Whether you need pillow blocks or flanged bearings, these models can be bolted to a variety of surfaces for ease of use. Our inventory contains a wide variety of mounted chock ball bearings, including pillow bearings, flanged ball bearings, reel and reel units, conveyor hangers, bracket flanges and insert ball bearings. These bearings are available in cast iron, stamped steel, stainless steel and nickel plated versions. Flanged mounted bearings are used when the axis of the shaft is perpendicular to the bearing mounting surface. They have a sealed bearing built in that is pre-assembled into a flanged housing. The housing contains a precision ground surface perpendicular to the bearing axis and two, three or four mounting holes, depending on the style. Bearings can be removed and removed, making bearing replacement easier and faster than traditional slew bearings that must be press-fitted into the housing. Flanged mounted bearings can also handle heavy loads, protecting the shaft from deflection that could cause vibration or other damage. Two-bolt flange mount bearings are diamond-shaped with two holes on each side of the bearing for mounting bolts. A line passing through the axis of the mounting hole forms a line passing through the axis of the bearing. Three-bolt flange mount bearings have three mounting holes that are radially arranged at 120 degrees to each other along the bearing axis, or on a triangular flange that is offset from the bearing axis. Four-bolt flange mounted bearings have four mounting holes that are radially distributed along the bearing axis. Four-bolt flanged bearings typically have round or square housings. Bearings used in flange mounts are called insert bearings. Flange mounts can contain many different bearing types. The correct type of selection depends on the desired application and operating specifications. Bolted roller bearings have a ball as the rolling element. They are used to provide smooth, low friction motion in rotary applications. The construction consists of an inner and outer ring, multiple balls, usually a cage or a ball separator. Rolling bearings have rollers as rolling elements. They are used to provide smooth, low-friction motion in rotating applications and have a higher radial load capacity than ball bearings. The structure consists of an inner ring and an outer ring, a number of rollers and usually a cage or roller separator. There are three main types of rolling bearings. Cylindrical roller bearings have high radial load capacity and moderate thrust loads. Spherical roller bearings are the most commonly used roller bearings in flange mounted bearings. They contain two rows of friction-reducing barrel rollers between an outer ring with spherical raceways and an inner ring consisting of two sloping raceways. Tapered roller bearings contain an inner ring, an outer ring and multiple tapered rollers. Separately, the inner and outer bearing rings are also tapered, similar to the conical sections. Due to the large surface area contact, tapered roller bearings are able to withstand heavy axial and radial loads. Needle roller bearings have needle rollers as rolling elements. They are similar to cylindrical roller bearings, but with a smaller diameter/length. By controlling the circumferential clearance between the rollers or needles, the rolling elements remain parallel to the shaft axis. Needle roller bearings are designed for radial load applications requiring a low profile. Plain and sleeve bearings for constraining, guiding or reducing friction in rotary or linear applications. They work by sliding instead of the rolling action used by ball, roller and needle bearings. Lubrication is essential for the operation of plain bearings to avoid overheating due to friction.
