PROFILE RAIL LINEAR GUIDE RUNNER BLOCK TYPES |
|
Intechangeable with other manufacturers NOOK
Precision Profile Rail Linear Guide Systems provide stable and efficient
linear motion guidance under variable speeds and high load
conditions.
NOOK Precision Profile Rail runner blocks are available
in two designs. One runner block design utilizes steel return tubes for
ball recirculation and the other utilizes a plastic end cap
for ball recirculation. The tube type recirculation system
enables the runner block to be used for higher speed applications.
The plastic end cap runner block is narrower in width than
the return tube style block. Eight different models are available
to meet the requirements of height, loads, mounting holes,
etc.

PRECISION PROFILE RAIL SYSTEM FEATURES |
Precise
Linear Motion
- Reference face and four grooves are ground simultaneously by
special grinding machines
- Simple construction of the runner block
- The rail’s high degree of straightness enhances final installation
accuracy
Equal Load Carrying Capacity
in Four Directions
- Steel balls recirculate between the rail and the runner block
and contact both surfaces at a 45° angle. Equal load can be applied
bi-directionally in both horizontal and vertical axes.
- The NOOK system is also capable of withstanding moment loads.
High Rigidity and High Moment
Rigidity
- The benefits of full radius ball raceways are well established
in the manufacture of precision ball screws. The circular shape
provides ideal ball to ball raceway contact giving great rigidity
and that is why NOOK has incorporated this design into their Profile
Rail Systems.
- The precise geometry and the square configuration of the ball
raceway is ideal for preloading and system rigidity.
- A range of preloads are available depending upon the requirements
for rigidity and load capacity. Preload is achieved by the selection
of precisely graded ball diameter.

Smooth
Operation at Both High and Low Speeds
- Precision ground full radius ball tracks provide smooth ball
circulation and reduced friction.
- The unique ball recirculation design permits stable, high speed
travel.
Reliability
- High quality materials are hardened by an advanced heat treatment
system resulting in increased durability and performance.
- Direct lubrication to ball grooves through a grease fitting
ensures adequate lubrication. The one-piece seal design retains
lubricant and effectively protects against contamination.
- Full radius ball raceways self-align to help absorb small mounting
errors and distributes related stresses evenly.
- The NOOK Profile Rail design has been extensively tested to
ensure long reliable life.
Versatile Installation
The compact design of NOOK runner blocks
offers greater design flexibility and several methods of mounting
compared to other linear guidance systems. Special retainers and
recirculation tubes prevent balls from escaping when the runner
block is removed from the rail. (remove slowly with no-load)
The combined effect of the features
listed above results in the following advantages:
- Improved working accuracy
- Greater performance control at low speed
- Low temperature operation at high speed
- Low friction
- Reduced machining and assembly costs
- Easy maintenance
