Linear Thrusters Specifications

Help with Linear Thrusters specifications:

Device Type



	Your choices are...
	Electric Thruster		Electric linear thrusters are electrically-actuated devices.
	Pneumatic Thruster		Pneumatic linear thrusters use double acting air cylinders mated to plates and shafts to provide cyclical linear motion.
	Hydraulic/Electrohydraulic Thruster		Hydraulic linear thrusters use double-acting hydraulic cylinders that are mated to plates and shafts to provide cyclical linear motion. Electrohydraulic linear thrusters are electrically-actuated devices, typically with double-acting hydraulic cylinders that are mated to plates and shafts to provide cyclical linear motion.

	Rated Force		Note: This is not the maximum static load.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Number of Shafts


	One		The thruster has one guide shaft.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Two		The thruster has two guide shafts.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Three		The thruster has three guide shafts.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Four		The thruster has four guide shafts.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	>Four		The thruster has more than four guide shafts.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Material



	Your choices are...
	Aluminum		A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Steel		A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
	Plastic		Any of numerous organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments.
	Other		Other unlisted material.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features



	Your choices are...
	Adjustable Stroke		End points or total stroke length can be adjusted.
	Brake / Clutch Combination		A combination brake / clutch assembly for slowing or stopping the linear motion (brake) and connection or disconnection of the drive mechanism (clutch).
	Bumpers / Cushions		Cushions or bumpers for softening impact at ends of stroke.
	Way Covers / Bellows		Way covers, which are sometimes referred to simply as bellows, cover the rails / guides for protection from dust and dirt.
	Protective Boot		Cover that protect moving parts against environmental damage.
	Cleanroom Rated		The unit is certified for use in cleanroom environments. Cleanroom requirements are typically specified in orders of magnitude of 1, 10, 100, 1000, 10,000, relating the particles per million and defining the particle size.
	Closed Loop Control		This is sometimes called servo control. The cylinder has external devices that feedback a signal to the pump control giving it position information. One configuration option is to use a servo / proportional valve on the cylinder.
	Double Carriage		The slide or stage is equipped with two sliding carriages.
	Double End Rod		Rod extends out of both ends of cylinder with attachment features such as threads on both ends.
	Integral Flow Control		Integral flow control incorporates a flow control valve or device that limits the amount of air or fluid.
	Ground Screw		Ground screws are made on a grinding wheel. Typically, this produces a screw with 0.0005 inch per foot lead accuracy.
	Holding Brake		Works in conjunction with the self-locking feature to increase holding force.
	Integral Sensor		Integral sensor to monitor position and/or proximity comes equipped.
	Intrinsically Safe		The device can be used in hazardous environments.
	Magnetic Switch		Magnetic switch (Hall effect sensor, reed switch) indicates whether thruster position is in retracted or extended position.
	Multi-position		Endplate can be actuated to different positions along its stroke, not just the endpoints.
	Non-rotating		Multiple rods or key feature to prevent the plunger from rotating.
	Rotary Axis		A multi axis stage where the last axis (Y or Z) is capable of rotary motion.
	Self-locking		When there is a loss of signal, the device will lock to its current position.
	Shock Absorbers		Pneumatic or hydraulic fluid absorption of shock.
	Integrated Overload Slip Clutch / Torque Limiter		A device used to allow for slip when torque exceeds overload limits.
	Stackable		The slide or stage can be stacked (one on top of another) to provide linear motion in more than one axis.
	Side Motor / Mount		A side motor or side motor mount is offered to fit in smaller spaces. This may be accomplished with a right angle gear box.
	Thermal Overload Protection		Motor has a thermal switch which trips when a preset temperature is exceeded.
	Vacuum Rated		The unit is vacuum qualified for use inside chambers.
	Water Resistant (Sealed)		Rated to resist moisture which could cause corrosion.
	Wipers / Scrapers		The unit is equipped with wipers or scrapers for cleaning the surface of the rails / guides.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
