Precision rail guides with balls - LWRB series
Space saving design
Smooth and accurate running behavior
Effective cage-creeping prevention
Available in very small sizes
Low friction and no recirculation elements
Anti-creeping system ACSM possible, even in such small dimension
LWRB precision rail guides with ball assemblies can be used where loads are light and/or low friction is required. This series contains the smallest dimensions within our product range. LWJK ball assemblies, which are used together with LWRB rails, are provided with a ball-retaining plastic cage. Additionally, Ewellix offers the precision rail guide LWRB with anti-creeping system ACSM that helps to keep the ball assembly in the intended position.
As standard, precision rails are manufactured from tool steel 90MnCrV8 (1.2842) with a hardness between 58 and 62 HRC. However, if required by the application, the rails can also be supplied in stainless steel, e.g. X90CrMoV18 (1.4112). All rails from the LWRE ACSM series are made of stainless steel X46Cr13 (1.4034) or X65Cr13 (1.4037). The hardness of stainless steel rails is between 54 and 58 HRC.
Standard rolling elements are made from carbon chromium steel 100Cr6 (1.3505) with a hardness between 58 and 65 HRC. Stainless steel rolling elements are available on request.
The cages of Ewellix rolling element assemblies are manufactured from hard plastic or aluminum. The material of LWAKE crossed roller units is POM, and for all other rolling element assemblies, PA 12 or equivalent, sometimes reinforced with glass fibers. Aluminum cages are made of AlMgSi0,5 (EN AW-6060)
