LL RE-CIRCULATING BALL BEARING (SERIES LL) Patented re-circulating ball bearing guide system. Excellent price / performance ratio. Several T-nut mounting options. Optional mounting accessory kits are available. Available in any length up to 6000mm. More than one carrier per rail can be mounted. T-nut slots for mounting Carrier with re-circulating ball bearing guide system Hardened steel bars T-nut slots for mounting Aluminum extruded profile, cut to the desired size The carrier is made from an extruded aluminum profile that houses the re-circulating ball bearing guide system. Thanks to its special profile, the carrier backlash is zero and (4) screws allow adjusting the pre-load on the bearings. Upon request, two or more carriers can be mounted on the same rail to increase the overall load capacity or to have two or more independently controlled slides. Backlash adjustment screw T-nut slot Re-circulating ball bearing guide system Hardened pins 684
