VALUED-ADDED PULLEYS FOR ANY APPLICATION
Carl Stahl Sava Industries is a pulley manufacturer proud to offer large, and small cable pulleys for virtually any wire rope and custom, miniature cable assembly application. Take a look below and see for yourself why the world over counts on Sava to keep your mechanical assembly needs moving at peak efficiency with our wire pulleys.
APPLICATIONS SUPPORTING CONTROL MECHANISMS, DRIVE SYSTEMS, RECORDERS, INDICATORS, WIRE ROPE DRIVE PULLEYS, POWER TRANSMISSIONS, AND METERING EQUIPMENT.
We are the right nylon pulley supplier if your application requires superior mechanical efficiency, our bearing-mounted, small nylon pulleys for wire rope are a cost-effective option. You’ll find our UP Series miniature pulleys from 0.50” to 1.75” diameter are ideal for moderate load and speed applications that don’t require more precise ground bearings. Alternately, we offer the SP Series Pulleys for devices that do require more precision.Browse UP series PULLEYS
APPLICATIONS INVOLVING HEAVY LOADS AND HARSHER WORKING ENVIRONMENTS ARE ACCOMMODATED BY OUR PULLEYS FOR HEAVY CABLES.
Because Sava is a steel pulley supplier that works with a number of industries, many of our customers design applications that will operate in corrosive environments or bear heavy loads. To meet even the most demanding environmental conditions, Sava offers our MP Series pulleys with bronze bushing, ranging from 0.75” to 2.00”.Browse MP series PULLEYS
APPLICATIONS REQUIRING LARGER CABLE FOR HEAVIER LOADS ARE ACCOMMODATED BY OUR LARGE CABLE PULLEYS.
For devices involving loads up to 410 lbs., Sava suggests our CP Series pulleys, which provide precision steel balls, case-hardened steel races, light lubrication, machined raceways and a zinc-plated surface. We offer the option of internal lubrication and plastic seals.Browse CP series PULLEYS
APPLICATIONS USING LARGER CABLES.
Sava also manufactures pulleys for larger cables. Our OP Series pulleys accommodate cables up to 3/8” with a 7x19 construction. You can choose an optional bronze bushing or roller bearing for your application.Browse OP series PULLEYS
APPLICATIONS USING SMALL CABLES OR CORD.
Sava’s bearing-mounted, LP Series nylon pulleys are principally engineered and designed for use with small cables and cords. Our small wire rope LP pulleys offer significantly increased mechanical efficiency, as compared with plastic pulleys, and are substantially less expensive than the bearing-mounted alternatives currently on the market.Browse LP series PULLEYS
CHOOSING THE CORRECT PULLEY
Our team understands that choosing the right cable assembly manufacturer, and pulleys for your cable assemblies requires thoughtful consideration, from bearing life, to minimum pulley diameter. Let Sava's engineering expertise guide you toward the best selection of wire rope pulley wheels.
When cable is used over pulleys, the cable life can be significantly prolonged by proper pulley groove design. Laboratory tests on wire rope pulleys prove that improper groove design reduces cable bending life up to 90%. These same tests show that doubling a pulley diameter can increase cable bending life up to thirteen times what is otherwise typical. Also, pulley diameters less than sixteen rope diameters fall into a range in which cable life is relatively low.
The life of steel cable pulleys is reduced as the groove radius changes from the contour of the cable to a flat surface. For maximum cable life, the groove should make contact with the cable on at least 1/3 of the cable circumference.
MINIMUM PULLEY DIAMETER
Recommended Minimum Pulley Diameters to Maximize Life.
|Cable Construction||Pulley Diameters (Root)|
|3X7||50 times rope uncoated dia|
|7X7||40 times rope uncoated dia|
|7X19||25 times rope uncoated dia|
|7X49||15 times rope uncoated dia|
MINIMUM PULLEY DIAMETER
The radius of bend has an effect on the strength of the cable. In order to take this into account in selecting the size pulley to be used with a given diameter cable, the following table can be used as a guide:
|Ratio "A" = Pulley DIA/ Cable DIA||Strength Efficiency compared to catalog strength in %|
