Rolling Bearings &
Plain Bearings
Rolling Bearings & Plain Bearings
 Rolling bearings support and guide rotating or oscillating
machine elements – such as shafts, axles or wheels – and
transfer loads between machine components.
 Plain bearings are used in many industries and across
many applications where there is a need to cost-
efficiently and reliably meet the challenge of oscillating
movements and possible misalignment.
Types
 Barrel roller bearings
 Crossed roller bearing
 Needle roller bearings
 Spindle bearings
Barrel roller bearings
 Barrel roller bearings are single-row, self-aligning roller
bearings. They comprise solid outer rings with a concave
raceway, solid inner rings with two ribs and a cylindrical or
tapered bore as well as barrel rollers with cages. The
bearings cannot be dismantled.
Crossed roller bearing
 Crossed-roller bearings are bearings for high-precision
applications whose dimensions conform to ISO dimension
series 18 as per DIN 616. They comprise outer rings, inner
rings, rolling elements and plastic spacers. The outer ring is
split and is held together by three retaining rings.
Needle roller bearings
 Needle roller bearings have a long track record as proven
machine elements for the design of radially compact bearing
arrangements with very high load-carrying capacity. In X-life
configuration, they now have an up to 50 % longer service
life.
Spindle bearings
 Spindle bearings are single-row angular contact ball bearings
comprising solid inner and outer rings and ball and cage
assemblies with solid window cages. They cannot be
dismantled. The bearings are available in open and sealed
designs.
