Reliable support for machine tool industry
Linear motion system is one of the most important elements of mechanisms and machines, which allows rectilinear movement of their units. Usually, all linear motion systems (hereinafter for simplicity referred to as "linear guides" for simplicity) are covered with dirt protection covers, and therefore they are rarely in usual circumstances.
However, these systems are used in almost all industries, such as electronics, production of medical equipment, construction, automotive, military, chemical, etc. Thus, linear guides have become an essential and necessary component of many modern devices and mechanisms.
It is believed that for the first time, people used rolling to move heavy loads instead of sliding back during the heyday of Egypt – in the construction of the pyramids. Round logs were placed under huge stones, thus facilitating the transportation task. However, despite such an early recognition of the advantages of rolling friction over sliding friction, linear bearings began to be widely used only in the middle of the 20th century.

LINEAR ROLLER BEARINGS
Linear roller bearings (LRB) are one of the most compact components of linear motion systems, which at the same time have the best load ratings.
The rollers move along a precision machined race located on the base plate. During operation, the linear roller bearing housing is stationary, while the load bearing rollers move.
The use of linear roller bearings allows obtaining stable and smooth linear motion, which ensures their application in the latest design developments of the largest manufacturers of machine-tool and other processing equipment.
For precision assembly of equipment, bearings are divided according to the mounting size into groups with a tolerance interval of standard mounting size: for the first group – 0-2.5 μm; for the second – 2.5 -5 μm; for the third -5 -7.5 μm, etc. The tolerance of the mounting size of a set of bearings installed in the same plane should not exceed 3 μm.

Linear Roller Bearing
ROLLER BEARING RS
Linear Roller Bearing is designed for use in rolling guides of metal cutting machines, robotic systems, instrumentation, laser and X-ray scanning systems, etc.
Supports perceive high loads acting perpendicular to the plane of movement of the actuators, and allow them to move with an unlimited stroke.
The working position of the supports is not limited (vertical, horizontal or inclined in the longitudinal plane).

MAIN PARAMETERS AND CHARACTERISTICS
ROLLING SUPPORT BEARINGS
SUPPORT BEARING RSB
Roller Support Bearings are designed for guides of rectilinear movement with a large stroke length of the moving units at speeds of up to 10 m/min. Guides with roller bearings have high stiness, low resistance to movement (demonstrated friction coe cient 0.002-0.004), high positioning accuracy in the absence of jumps at low feeds, high durability with intensive work at high speeds. The support structure is a rigid thin guide around which rolling bodies (rollers) are run around in a closed path. Rollers are kept from falling out by clips and springs.


The supports are mounted on the machine assembly with screws and ground. The cleanliness class of the working surfaces of the guides along which the support rollers move is not lower than ν8, hardness HRC 56-62.

ROLLER SUPPORT BEARINGS
SUPPORT BEARINGS R88
Roller support bearings of the R88, R88U, R88Sh models are intended for use in rolling guides. They allow smooth movements of the machine parts with a large stroke (almost unlimited) with speeds from 1 to 10 m/min. with small friction losses (demonstrated coefficients of friction .002. . . . .0.004) and perceive significant loads acting in the direction perpendicular to the plane of movement of the component of the machine. Roller bearings are intended for use in machines of normal and high accuracy.
