 ROLLON
Corporation’s Compact Rail is totally different from all the other
linear bearing systems available in the marketplace. Most linear
bearings are descendents of heavy machine tool bearings and
therefore, by their very nature nature, tend to be slow,
recirculating-ball carriages mounted on simple round or profiled
shafts. In designing the Compact Rail, ROLLON started from scratch
and designed a linear bearing system based on the needs of modern
design engineers.
ROLLON realized that while most
linear bearings are used in applications requiring a degree linear
precision, few require machine tool-like, ultra-high precision. High
precision grade rails (most popular round or profiled shafting fall
into this category) are difficult, time consuming, and expensive
systems that require machining of the mounting surfaces (a cost
which often cannot be passed on to the customer).
ROLLON’s Compact Rail is a simple,
precision, linear bearing system that is easy and inexpensive to
mount to all - even non-machined- surfaces. In addition, Compact
Rail will self-align to another rail even if mounting surfaces are
not perfectly parallel.
Many linear bearing applications
operate in dirty or contaminated environments and engineers are
often forced to specify external bellows or other costly protective
devices. ROLLON has specially designed the Compact Rail to ensure it
is a well-protected system. The sliders run inside the hardened
steel rails where they are protected and they have spring-loaded
wipers that protect the shielded or sealed bearings from debris and
damage.
Feedback from engineers in the field
told us that recirculating ball sliders were slow and noisy and this
affected the quality of their machines. Compact Rail is a fast (up
to 9 m/s) and silent system (much quieter than recirculating ball
systems). To help ensure new machinery is as maintenance free as
possible, Compact Rail has “lubed for life” bearings with
patented wiper technology that lubricates the system as it runs.
The Compact Rail Advantage:
The original design of ROLLON’s Compact products allows them
to offer many unique advantages:
Internal Raceways Provide A
Compact And Well Protected Solution
 Compactness
is an important advantage in those applications where compact linear
bearings would be of clear benefit to the ease of construction and
of benefit to the design itself.
ROLLON’s unique design places the
raceways on the inside of the rails where they are protected from
bumps or shocks. The sliders, which are protected from debris and
impurities with their incorporated spring-loaded wipers run inside
of the rails. The COMPACT RAIL system fits into an extremely limited
space and offers the best-protected solution available for even the
most for critical environments.
Maintenance Free
The self-lubricating wipers available for the NT series sliders
continually apply a thin layer of lubrication to the system. This
constant lubrication assures 2 millions cycles before additional
maintenance or substitution is required. The cost savings of this
system when compared to other systems are incredible. The kits can
also be refilled by using the grease nipples on the heads. This
advance in lubrication technology does not add any length to the
sliders as it fits into the same dimensions as the standard heads.
High Speed = High Productivity
For a wide range of applications and especially in the
automation field, the most important bearing feature is often speed,
as the speed determines the productivity. Higher working-speed
results in higher output. The Compact Rail family of products offers
solutions that can be run at nearly 9m/s; an incredibly high speed
compared to common systems.
Silent Operation Level
With today’s restrictive regulations for admissible working
noise levels, it’s become more and more important to keep a
machine’s operation noise level as low as possible. The Compact
Rail system offers very low operation noise level, even when working
with high loads and high speed. This is the opposite of
recirculating ball sliders that become much noisier as the speed and
load increases.
 Quick
And Easy Assembling
The cost of assembly time is often neglected during the
designing stage as many engineers assume that the time for assembly
is a fixed factor, equal for all linear bearings. The Compact Rail
system has been developed to offer high cost savings on assembly
time. In addition, substantial cost savings is also gained due to
low requirement of the accuracy of the mounting surface finish.
The self-aligning rail combinations
T/U and K/U, the self-aligning rails with C’sunk fixing holes, and
the small number of fixing screws due to the large pitch of the
rails, all offer the most efficient time saving characteristics.
Optimum Preload Setting
For applications where the stiffness or low friction is of
critical importance, the Compact Rail system offers the unique
possibility of allowing the preload on standard sliders to be set
according to the exact needs of the application.
All sliders are interchangeable, by just simply resetting the
preload.
