BRANDED BERAINGS
Deep Groove Ball Bearings
Deep Groove Ball Bearings is the most common type in roller bearings. The basic Deep groove Ball Bearings structure includes: an
outer ring, an inner ring, a group of steel balls and a group of retainer.
Cylindrical Roller Bearings
The structure of Cylindrical Roller Bearings is the inner ring and outer ring which can be separated. Cylindrical Roller Bearing without
sidewall in inner nor outer rings can be used as a free-end bearing because its inner and outer rings can move relative to the axial.
Page 18
Tapered Roller Bearings
Tapered Roller Bearings are detachable type, which the cone inner ring component with roller and retainer can be installed
separately from the cone outer ring. Tapered Roller Bearings are cone-shaped inner and outer ring raceway and tapered roller
arranged between the two.
Spherical Roller Bearings
Spherical Roller Bearings have inherently self-aligning function and also very strong. Double row roller make the bearings can bear
heavy load. Spherical Roller Bearings have two rows of rollers and both use the same raceway in outer ring.
Page 19
Thrust Ball Bearings
The compositions of Thrust Ball Bearings are seat ring, bearing ring and steel roller retain. Seat ring, bearing ring and the rollers is
separated and simple to assemble and disassemble.
Self-aligning Ball Bearings
Self-aligning Ball Bearings are the bearings with drum-shaped roller between inner ring with two raceways and outer ring with
sphere raceways.
Page 20
Angular Contact Ball Bearings
Angular Contact Ball Bearings are can bear radial load and axial load. Single row Angular Contact Ball Bearings only can bear axial
load in one direction. It will lead to an additional axial force when it bear radial load.
Needle Roller Bearings
Needle Roller Bearings are roller bearings with cylindrical roller. Compare with its diameter, the roller are both long and thin and this
kind of roller called needle.
Page 21
Linear Bearings
Linear Bearings make up of outer tube, steel roller, steel roller retainer and two retainer rings. Retainer is set out from the outer
tube and fixed by two retainer rings.
Kaydon Reali-Slim® Bearings
Reali-Slim® ball bearings are available with a Thinfinite™ variety of separator options to space the rolling elements uniformly and
prevent contact between them. Separator types available include: continuous ring "snap-over pocket," continuous ring circular
pocket, formed wire, toroid, PTFE spacers, and ball bearing spacer separators.
