PRG with needle roller assemblies
LWRM/LWRV series and LWM/LWV series

Precision rail guides with needle roller assemblies enable linear guiding systems to be designed for heavy loads and with maximum rigidity. The cages are available in two different materials. LWHV needle roller assemblies (fig. 1) consist of a plastic cage with retained needle rollers. LWHW needle roller assemblies (fig. 2) have aluminium cages with retained needle rollers. To meet all requirements regarding outer dimensions and interchangeability, SKF offers the LWRM/LWRV series, which belongs to the Modular Range, and the LWM/ LWV series. LWM/LWV rail guides are widely-used, especially in the machine tool industry. As the internal geometry is identical for both series and the same needle roller assemblies are used, the load ratings are identical.
