Iron shielded deep groove ball bearing is one type of ball
bearings. shields are non-contact metallic (carbon or stainless
steel) devices which allow high-speed operation but offer limited
protection against the ingress of moisture and dirt. but do not
protect against liquids. They add no friction during operation and
therefore do not generate heat build-up. Iron shielded deep groove
ball bearings often have steel shields installed on one or both
sides and are pre-lubricated with grease. While many different
retainers are available, pressed steel cages are most commonly
With one shield (-Z) on one side or two shields (-2Z/ZZ) on both
sides; Due to the manufacturing processes used, open bearings can
have turned recesses in the outer ring for shields.
XKTE - Ball Bearings and Rolling Bearings in Conveyor Technology
XKTE is the specialist in rolling bearing technology for the
mechanical application of continuous conveyors.
Feature of Rubber Sealed deep groove ball bearing:
Shielded bearing for conveyor idler usually need large clearance
such as C3/C4, while can not use standard Bearing, they will cause big running
resistance, brake and reduce lifetime of bearing. Bearing must be
provided to ensure concentricity of the inner and outer race.
Super Finished Surface Technology
Dimensions such as the outer and inner diameters and the width are
ground to micrometer (one-thousandth of a millimeter) precision, as
is the groove, a key internal structure formed between the inner
and outer rings in which balls run.
Thicker Inner & Outer Ring
The ring is the main part and the important part of the idler
roller bearing. Best idler roller bearing has deep groove ball, and
large clearance. But deep groove doesn`t mean to dig the channel
with a simple way of enlarge the steel ball. The thickness of the
bearing is certain, so to get the ball big and the groove deep will
shorten service life. Our XKTE bearing uses way of thickening ring
to get the standard of deep groove and large clearance, improves
the anti-stuck performance, and effectively increases the service
Grease selection of roller bearing
Many customers ignore this most critical point. The
thirty-thousands-hours operation is a very long term. This has to
be guaranteed by enough quality and quantity grease. And this
should also be taken into account of working in different seasons.
