2 <strong>Linear</strong> guides Precision rail guides LWR .. / LWRB .. LWR rail guides are well-proven, limitedtravel linear guides used in numerous applications. They consist of two identical rails where cross roller cages or ball cages are inserted, depending on the application and size. LWR rail guides with cross roller cages are robust linear bearings with high load-carrying capacity. Their special characteristics make them suitable for a large proportion of linear bearing arrangements with limited travel. LWRB rail guides with ball cage can be used to advantage where loads are light and easy running is required. They are available for sizes 1 and 2. Because of the large number of possible combinations, all components of LWR/LWRB rail guides must be ordered separately, for example: 4 rails LWR 2 cross roller cages LWAL 8 end stops LWERA. LWR ..
