Each of Tusk's product types include a subminiature member useful in today's increasingly small mechanical mechanisms in modern industrial machinery and instrumentation

Miniature And Subminiature Slides:
Small in size, lightweight miniature linear bearings and components feature the same high quality materials and construction as used in the larger versions

ECONOMICAL LINEAR SLIDES
For guiding, supporting and reducing friction in reciprocating mechanisms. Tusk ball and crossed roller slides utilize a straight line design which allows for low friction characteristics and inexpensive production methods resulting in an economical alternative in linear bearing design.

Linear Ball Bearing Slide assemblies:
High precision subminiature, easy to install and use, ball slides reduce friction between moving parts in all types of automated equipment. Sizes range from: 0.23 high, 0.38 wide, 0.75 long, load capacity 1.5 lbs. up to 1" high, 2.62" wide, 15" long, load capacity 205 lbs.

Linear Crossed Roller Slides:
Overall dimensions and characteristics are the same as ball slides, however, crossed roller slides feature high capacity rollers and flat raceways to allow extremely smooth movement and 6-8 times the capacity of a similarly sized ball slide. Features include positive stops and travel range of 0.5" through 12".

UNLIMITED TRAVEL SLIDES
Unlimited travel design allows a relatively small carriage to travel the entire length of the mating rail or shaft. The rolling elements, (balls) recirculate along on oval path entering and leaving the load zone as the slide moves. The linear ball bearing and shaft type is available as separate components or complete assemblies. the square rail slide guide type can be purchased with more than one carriage on the common rail to add versatility and stability.

Recirculating Slide Guides:
Differing base and lengths allow fully supported travel of the recirculating member along the entire length of the base rail. The SG series is interchangeable with those of other manufacturers and available in stainless steel, sealed, and in a wide cross section type for increased stability and greater overhung load capacity. Travel up to 30 and high load capacities are available in this all steel series of high performance slide guides.

Recirculating Ball Bearings: A wide range of linear bearings are offered: self-aligning, integrally sealed, resin retainers, open and adjustable. With diameters ranging from 1/4" to 1", the new "Ultimate Series" adds the advantage of being completely self aligning (1.0 degrees in all directions) allowing the designer to allow for misalignment without the extra expense of precision machining of the mounting rails and supports. Recirculating Linear Ball Bearing Pillow Blocks: Linear bearings are mounted in easily installed aluminum pillow block housings. The bearings range from 3/16" to 1" inner diameter and are offered in closed, open and adjustable styles in either high precision or the new "Ultimate Series" self-aligning bearing. Linear Bearing Shafts: AISI C- 1060 case hardened and ground shafts are available in steel and stainless 1/4" through 2" diameter cut to length. These linear bearing grade shafts are ideal for use with Tusk linear bushing bearings and pillow blocks. Straight, rigid and smooth, these shafts offer low friction linear travel and high wear resistance for long life and high precision. Shafts are available plain or predrilled for mounting to supports. Linear Shaft Supports And Hangers: Aluminum shaft hangers offer predrilled mounting holes and locking fastener to assure precise support and location of linear bearing shafting. Continuous 24" or 48" aluminum shaft supports are ideal for use over long spans where continuous support of open linear bearings is desired. Plain or predrilled models are offered. A low profile series of predrilled continuous supports is available in steel for high rigidity and straightness. Linear Ball Bearing Assemblies: LBA assemblies provide a stable linear bearing platform suitable for mating with a lead screw and motor drive or air cylinder system.

Actuated Stages
Tusk actuated stages are multi-axis positioners available with manual micrometer head actuators for accurate measurement of stage location and settings. The AutoSlide lead screw actuated positioners are motor ready with coupling and nema motor frame bracket.

Auto Slide:
Motor ready, lead screw drive, zero backlash coupling, one, two, or three axis, standard mounting hole pattern carriage and base.

Multi-Axis Positioning Slides (Ball or Crossed Roller):
Micrometer driven and spring loaded; stages are available in one, two, or three axis configurations with either ball or roller internal bearings for precise intermittent positioning of probes, sensors, mirrors, cameras, focusing lenses and anything which needs to be located in space precisely and accurately. Subminiature model BPS-X features 0.25" travel and a 0.75" work surface.

EXTENDED TRAVEL SLIDES
Short carriages move over the precision twin rail system. Adjustable preload allows manipulation of play in the carriage. Patented alignment design assures consistent rail spacing. An extremely low cost approach to precise linear motion

Econo-Rail Slides:
Twin rail with interchangeable carriages. Up to 9 feet of travel. Recirculating or precision roller configuration

HIGHEST CAPACITY SLIDES
Ideal for impact and overhanging loads, Tusk heavy duty slides utilize dovetail plain bearing design
with tapered gibs or crossed roller slide design.

	Heavy Duty Crossed Roller Tables: Aluminum base and carriage and precision hardened and ground V-grooved rails give the RT series of crossed roller tables the greatest load capacity in the Tusk line. Straight line accuracy of 0.0001" per inch of travel and a maximum capacity of 723lbs. allows the designer to accurately guide loads and forces. Sizes range from 0.590" high, 1.181" wide, 1.969" long to 1.7" high, 3.9" wide and 14" long.
	DoveTail Slides Tusk DoveTail Slides are made of continuous cast G2 40,000 PSI pearlitic grey iron. This material may be milled, drilled, tapped, etc. for altering or mounting purposes. Short carriages with long travel, up to 12 inches, or long carriages with short base, all in one "Precision DoveTail Slide", that may be mounted in any position.
HIGHEST ACCURACY LINEAR SLIDES Parallelism of 80 millions of an inch is achievable with the CR series The EA and LT series offer precise runout and straightline accuracy.
	Crossed Roller Rail Sets: Crossed roller rail sets allow custom installation of precise smooth linear motion in your assembly. Each set consists of four v-grooved rails which are tapped and counter-bored, two sets of rollers in retainers and four end stops. The rollers are alternately opposed at 45 degrees to allow loads from any direction.
	Extreme Accuracy Ball / Roller Slides: The extreme accuracy series is available in ball or crossed roller design with repeatability of 0.00002 inches and straight line accuracy of 0.00004 inch/per inch of travel. The flanged base type provides additional stability.
	Low Profile Crossed Roller Tables: An aluminum carriage and flangeless base distinguishes this low profile series. The base rail consists of one double V-grooved rail which interfaces with the two outer rails attached to the carriage. Extremely smooth low friction travel makes this series ideal for high rate reciprocating mechanisms. Interchangeable with those of other manufacturers. Three low profile heights are offered: 0.315", 0.472", and 0.630" with travel up to 5".

LINEAR BEARING LUBRICANTS
Ideal for reciprocating mechanisms improves the life and performance of all types of linear bearings and moving parts.
Lubricants:
Linear lubricant is a colorless and odorless Teflon/mineral oil liquid available in one ounce tubes. Slidicone is a silicone based spray lube.

MISCELLANEOUS COMPONENTS
Linear actuation components allow precise measurable movement.
TLS Series Anti-Backlash Lead Screw Assemblies:
Assemblies offer high accuracy, long life and smooth quiet operation. The anti-backlash nuts are self lubricating and wear compensating.

Micrometer Heads:

Tusk micrometer heads offer easy to read distinct figures for precise settings. Select our micrometer heads for machine tools, fixtures, special gages and all applications requiring micrometer accuracy in settings and adjustment.
