PM frictionless slides, are ready-to-install 1-axis components for precise limited linear movements. The crossed roller slides, use PM linear bearings, are factory pre-loaded, to assure high accuracy, extremly low uniform coefficient of friction (<0.003) and a long operation lifetime.

Each type comes with mounting holes drilled to a standard configuration to permit quick assembly in the application. The mounting surfaces of the slides are precision ground, to achieve the best possible operating results.

Aluminum, clear anodized finishing.

Features and Specifications

• Incorporates pre-loaded linear bearings type RSD and double-sided track-rail, including roller cages.
• Slide-top and -base have equal lengths.
• 2 standard strokelengths (N- and L-stroke). Linear strokes are limited by internal mounted endstops, two in the slide-top and one or two in the baseplate, depending on RTLA or RTNA version. N-stroke: for normal stroke/travel, with normal loads. L-stroke: for longer stroke/travel, with reduced loads.
• Size Ø1.5 and Ø2 mm: use in each direction (with brass roller cage type CC). Size Ø3, Ø4, Ø6 (pitch t=9 mm) and Ø9mm (pitch t=14mm), horizontal fitting model (with steel roller cage type AA). Vertical fitting model (with brass roller cage type DD).
• All mounting surfaces are precision ground.
• One flank of the slide ( the side opposite to the adjustment screws) is ground parallel to the linear bearings to serve as a Reference Face.
• The slide-top is provided with tapped attachment holes, drilled to a standard configuration. The slide-base is equipped with countersunk-bored holes, which accept sockethead screws.

Options

• Cages can be replaced by plastic crossed roller cages
• type KZR or type KKLK fitted with balls.
• Higher accuracy grade slides.
• Stainless steel version.
• SF-Class technology for maximum performance.
• High vacuum modification.

PM-Bearings is the precision leader in mechanical linear bearings. The ACC (anti-creep cage) option now allows designers to take advantage of the special qualities of non-re circulating bearings, completely eliminating past concerns of cage creep. In addition, PM produces a complete line of slides, positioning tables, and stages for linear and rotary motion using ball screw, lead screw, and linear motor drives. The fastest growing part of the PM product line is the special systems designed to meet specific customer specifications. These products allow the customer to consolidate the responsibility of purchasing, machining, and assembling various components into a tested unit, reducing the number of suppliers, and dramatically reducing their internal costs.
