required to deflect the belt should compare with the deflection forces noted in the chart below. Also notice for V-belts that deflection forces vary from 

Adjustable for 10" to 170" belt span and up to 35 pounds of tension. Proper tensioning is recommended to avoid premature V-belt wear.

More Information. Tensioning Standard 2-Pulley V-Belt Drives With a compression Tension Gauge: 1. Measure the span length P. (diagram within the images) 2. Divide span length P in inches by 64, then set the large o-ring on this calculation, i.e. if P measures 16" then set the o-ring at 16/64" (or 1/4") of deflection. 3.

Belt Tension for Optibelt V-Belts and Kraftbands . Table 8. V-grooved pulleys optibelt SUPER X-POWER M=S are used with pulleys according to DIN 2211, 

3. Over tensioning shortens belt and bearing life. 4. Keep belts free of foreign material which may cause slip. 5. Make v-drive inspection on a periodic basis. Under-tensioned belt drives

First two digits indicate belt top width. 67 = 3/8",68 = 1/2", 69 = 21/32" Last two digits indicate length in inches. Example:6823 Belt has a 1/2" top width and a 23" O.C.69_ 5LK 68_ 4LK 67_ 3LK 3/8" 7/32' 1/2" 5/16" 21/32" 3/8" PowerBand®Joined Belts Made by joining two or more single V-Belts with a permanent, high strength tie-band.

TENSION GAUGES. FOR OPTIBELT V-BELTS AND. RIBBED BELTS. This simplified method for static tension measuring should be used for installation and maintenance 

Tensioning V-Belt Drives with a PowerDrive Tension Checker should be maintained at the minimum value as indicated in the chart. “Used Belt”.

Force – Deflection Method of belt tensioning: · Measure the belt span length and calculate the desired deflection distance (1/64” per inch of span length) · Using 

V-Belt Tension Ranges for Manual Tensioners. Always use a belt tension gauge that indicates static tension, tension from the Installation Chart.

T c = add-on tension allowance for centrifugal force, from T able 31 on page 7. Note: The value of T s is for an individual V -belt. If a banded V -belt is used, refer to ÒElongation Method.Ó Step 4. Calculate the recommended minimum and maximum deflection forces (P), in pounds: T s + Y (1.5 x T s) + Y P min = 16

V-Belt & Multi-Rib Series V-belt tensioning adjustment can be made using a tension gauge or other type spring scale, using the following pro-cedure. After seating the belts in the groove and adjusting chart below. Also notice for V-belts the deflection forces vary from the initial "run-in" values which are greater

Proper belt tension ensures optimum performance of a vehicle's accessory belt drive system. Select from the dropdown options below to find the appropriate belt tension for your belt.

6. V-belts permit a wide range of driven speeds, using standard electric motors. 7. V-belts dampen vibration between driving and driven machines. 8. V-belts are quiet. 9. V-belts act as a “safety fuse” in the powertrain. 10. V-belts and sheaves wear gradually

V-Belt Tension Gauge Proper tension is the key to long, efficient, trouble-free belt operation. When you install a new set of belts, use the gauge to establish correct tension. Then, to maintain performance, re-check belt tension after 24-48 hours. The payoff is maximum belt life, reduced downtime and uninterrupted equipment service. Plunger with

For a given belt length, the distance between the pulley axles can be calculated using the above formula if the diameters of both pulleys are known. For example, consider calculating the

Proper belt tension is a critical step when installing a belt. V-belts operate on friction; the friction is multiplied by the mechanical advantage of the
