Custom Bearings for Material Handling System: Cam Followers KR35PP | KRE35PP
Bearings for Material Handling System
Bearings for Material Handling System Track roller bearings can
withdraw heavy load rating and shock load rating by their thick
outer race. They are ready-to-fit units and are intended for all
types of cam drives, tracks, conveyors, material handling systems
and so on.
According to customer's application, the OD surface can be designed
to be flat , crowned and other special ones. Cam rollers with
crowned runner surfaces should always be used where angular
misalignments with respect to the track expected and edge stresses
kept to a minimum.
Track roller bearings are based on ball bearings, needle roller
bearings as well as cylindrical roller bearings. Because of the
wide variety of designs they are suitable for the most diverse
operating conditions.
Tolerances:
WD track roller bearings are produced according to Normal tolerance
P0 standard, except for the tolerance of the crowned runner surface
diameter.The values for tolerances tally with ISO 492.
Clearance?
C2, C0, C3, C4, C5 radial internal clearance are available and also
special radial internal clearance is available as customer's
application providing the clearance limits are as specified in ISO
5753.
Load rating?
Dynamic load rating conform to ISO281/1 and static load rating
conform to ISO76.
Lubrication ?
The track roller bearings, filled with lithium grease, have a good
anti-rust capability and can work among the temperature range
from-30?to+120?. Generally speaking, they are greased for life and
are maintenance-free under normal working condition. However, if
they are subjected to moisture or solid contaminants, or if they
keep runing for a long periods under temperatures above 70?, they
should be relubricated with same grease by the oil hole in the
inner race or other lubrication method. High and low temperature
grease are also available according to customer's request.
The WD track roller bearings consist of:
? Combined bearings
? Cam followers
? Mast rollers and chain pulleys
? Cam roller bearings
? Supporting rollers
? Other non-standard rollers
WD Cam Followers are essentially needles or cylindrical rollers or ball bearings,
which are with a thick-walled outer race. The outside (runner)
surface of the outer ring is crowned which serves to preventing
edge stress if the cam follower runs in a titled or inclined
position. Cam followers are ready-to-mount units which are filled
with grease. They are suitable for all types of cam drives, tracks,
conveyor system and etc.
Instead of an inner race, cam followers have a solid stud which is
threaded, so they can be quickly and easily attached to appropriate
machine components by means of a hexagonal nut. Axial guidance for
the outer race is provided by an integral flange at the head of the
stud and a side washer pressed on to the stud, or by the roller
complement.
WD cam followers are available in different designs which have the
same dimensions and differ only in their internal designs.
Generally, the cam followers have a concentric seating on the stud,
but some are also available with an eccentric collar which is
shrunk on to the stud. Cam followers with eccentric collar enable
an optimum interaction with the cam to be obtained and also allow
less stringent manufacturing tolerance to be used for the
associated components.
Application of WD cam followers:
1) Escalator;
2) Moving sidewalk;
3) Elevator;
4) Conveyor system;
5) Lifting machinery;
6) Automotive line machinery;
7) Material handling equipments;
8) Linear motion guidance equipments;
9) Cam drives;
10) Screw drives;
Advantages of WD Cam followers:
1) Optimized structure and reliable quality;
2) Modifying the contacting surface logarithmically to reduce the
contact stress;
3) Full ranges of precision standards for different working
conditions;
4) saving the mounting and maintaining costs with ready-to-fit
units;
5) prolonging the working lifespan by filling grease for life;
