Applied shaft
Type diameter (mm) Composition of nominal number
KLM

KLM 06 L
This type composed of an outer ring,
steel balls and a cage is a cylindrical Tail code
bearing for the most universal
П3ʙП40
applications, which ensures precise and Inscribed circle
smooth infinite linear motion due to its diameter
outer ring of high rigidity.
Type code

KLMʝS
his type is composed of an outer ring,
KLM 30 S
steel balls and a cage. And both of the
outer ring and the cage have an axial slit,
Tail code
as illustrated, so as to enable to shrink
the inscribed circle diameter of the cage
П16ʙП40
by pressing the outer ring in radial Inscribed circle
diameter
direction from the housing and to thereby
adjust radial clearance from shaft. Type code
Thus, this type also ensures precise and
smooth infinite linear motion.

KLMʝP
This type is composed of an outer ring,
steel balls and a cage. And the outer ring
and the cage are of arc sectional shape,
from which one row of balls (equivalent to KLM 30 P LL
50˚ to 60˚ degree spacing) is removed.
Thus, the arc cross-sectional ring and Tail code
cage with 50˚ to 60˚ degree opening
allows the bearing assy to pass through П16ʙП40 Tail code
a shaft support truss or a shaft support
stand on midway of the shaft stroke. Inscribed circle

This type also ensures precise and
smooth infinite linear motion, similarly to Type code
other types.
The bearing radial clearance can be also
adjusted.
KH

This type is composed of an outer ring,
KH 20 30 LL
steel balls and a cage and the outer ring
is cylindrical similarly to that of Type KLM
and drawn from a steel plate by precision П6ʙП50 Tail code
deep drawing, then enabling to design a Width
compact bearing construction of low With seal
section and lightweight. This type also П10ʙП50 Inscribed circle

ensures precise and smooth infinite linear
motion similarly to other types. Type code
