USED THK RSR 12W  LINEAR BEARING ASSEMBLY Your purchase is for 1 assembly, unless you increase the order quantity obviously. These linear rails have the following specs: Recirculating Ball Bearing Technology Mechanical Stroke:  19.5mm  (0.80") Overall Rail Length: 70mm (2.74") Rail length from inside stop pins: 60.5mm (2.38") Rail Width: 24mm (0.944") Carriage OAL: 41.2mm (1.622") Carriage Width: 40mm ( 1.575") Carriage Screw Thread (4x): M3 Rail Mounting Screw Thread (2x): M6 Please refer to the documentation from THK for the specific details on load ratings and other dimensions. https://tech.thk.com/en/products/pdf/en_a01_250.pdf These have been cleaned and fully lubricated. They move very smoothly and are tight with no perceptible play in the 2 primary directions of bearing support.  With my inventory, I have assemblies that are marked  RSR 12W  and RSR 12WV. They are mechanically and dimensionally the same. If you order one piece, you may get either a 12W or 12WV. If you order many assemblies, I will attempt to provide all the same part number for consistency, inventory allowing. All have metal/rubber shields on underside of the carriage to protect against contamination. Refer to the photos of the underside. Some of them also appear to have metal/rubber shields on the ends others do not. I cannot guarantee the unit you get will have end shields. Please be aware, if you attempt to remove the stop pins and slide the carriage off the rail, 1000's of tiny ball bearings will fall out of the carriage and will render the rail/carriage useless (unless you painstakingly re-install every one of them into the carriage). There are safe ways to transfer the carriage to another rail without ball loss. I cannot offer refunds for assemblies which have been damaged due to the buyer's failed attempts at disassembling these intricate assemblies. Please check out my other auctions.
