Product Description
Flange mounted bearings are used when a shaft axis is perpendicular
to the bearing mounting surface. Available in 2, 3, or *-hole
configurations, flange mounted bearings provide a method of
accurate mounting fits and load support. *-bolt flanged bearings
have a diamond shaped flange with 2 mounting holes. Most *-bolt
flanged bearings have a circular mounting flange with three,
equally spaced mounting holes. Other hole configurations, such as
an offset pattern, are also available. *-bolt flanged bearings have
a square or round mounting flange with four mounting holes.
Selection of the appropriate bearing can be accomplished with
knowledge of the shaft size and radial and thrust load
requirements. Bearing type choices for flange mounted bearings
include ball bearing, needle roller bearing, plain bearing, and
roller bearing. In a roller bearing the rolling element is a ball.
Ball bearings are used to provide smooth, low friction motion in
rotary applications. Construction consists of an inner and outer
ring, balls, and usually a cage or ball separator. In a needle
roller bearing the rolling element is a needle roller. Needle
roller bearings are designed for radial load applications where a
low profile is desired. Bushings / sleeve bearings, also called
journal or plain bearings, are used to constrain, guide, or reduce
friction in rotary or linear applications. They work by means of
sliding action as opposed to the rolling action used by ball,
roller and needle bearings. As in all bearings, proper lubrication
is required to reduce wear and friction. Terms such as fluid film,
self-lubricated, hydrostatic, and hydrodynamic are commonly
designations for plain bearings. In a roller bearing the rolling
element is a roller. Roller bearings are used to provide smooth,
low friction motion in rotary applications. Construction consists
of an inner and outer ring, rollers, and usually a cage or roller
separator. The principal types of roller bearings are cylindrical,
spherical, and tapered. The most common type of flange mounted
roller bearing is a spherical roller bearing, which is a
self-aligning, double row, combination radial and thrust bearing.
Important dimensions to consider for flange mounted bearings are
shaft size and overall height from the mounting surface. Shaft size
specifies the maximum diameter of the shaft or the bore diameter of
the bearing. Overall height above mounting surface is important to
take into consideration for low clearance applications. Housing
material choices for flange mounted bearings include pressed steel,
stainless steel, cast iron, and plastic. Bearing material choices
include steel, stainless steel, sintered bronze, graphite or metal
alloy, sintered iron, and plastic. The choices for shaft securing
method for flange mounted bearings include none, setscrew, and
locking collar. Lubrication choices include relubricatable and
self-lubricating.
