2THE TOOLS NEEDEDChocksThread GaugeAnglesCalipersOmni Metalcraft Corp.Tape MeasureChain SamplesMagnetCoating SamplesAbout This GuideThis guide introduces the tools needed to measure a roller and will walk you through the process.If at any time through the measurement process you are unsure of a dimension or specification please contact anOmni Metalcraft Corp. Customer Service Representative at (989) 358-7000 to ensure the accuracy of your order.

GUIDELINESUsing the Roller ChocksSet the roller chocks under the roller tube, close to the ends. Allow the ends of the roller to overhang the chocks.If the roller has sprockets, allow the sprockets to overhang the chocks as well.n Additional spacers may be needed under the chocks if the sprockets are too large to allow the roller to sit level.n Short rollers may only require a single chock for support.- Rollers less than 6" in length can be measured using only the calipers and do not necessarily require beingsupported by the chocks.Using the Anglesn The Angles are used to provide a straight vertical edge to measure from.- They are placed on either side of the roller like book ends.- The vertical edge is placed against the desired surface to be measured.- When both angles are in place the tape measure can be used to measure between them.- This method provides a very simple yet accurate measurement between hard to reach surfaces.3

4GUIDELINESUsing the Calipersn The dial calipers measure items shorter than 6".n There are three types of measurements that can be taken by using different parts of the calipers:external, internal, and depth.InternalExternalDepthn The calipers are read by first looking at the ruler along the neck.- The ruler is marked in increments of 1/10" or 0.1".- Read the ruler measure to the 0.1". Example: 1.3"n Next, read the dial.- The dial is marked in increments of 1/1000" or .001".- Read the dial number. Example: Dial reads 75, it is .075".n Add these two readings together for the measurement.Example:The ruler reads 1.3".The dial reads .075".The measurement is then:1.3" .075" 1.375"*Hold the calipers snug, but not too tight.DialRulerA Note on AccuracyThe tape measure is capable of taking measurements that are accurate to the nearest 1/32". To ensure the consistencybetween your measurements and ours, measure to the nearest 1/32".The calipers can provide measurements that are accurate to the nearest 1/1000". At this level of accuracy, tolerances inthe components can be a factor. For instance, a hex axle may measure as being .4370". The axle is actually a 7/16" hexaxle but, due to the manufacturing tolerances of the material, the measurement may not be exactly .4375".Metric MeasurementsBoth the tape measure and calipers use English standard units (inches). It is important to keep in mind that a rollermay be built with metric components. If your measurements are coming out with strange numbers then remember tocompare them to metric units. 1.00" 25.4 mm

GETTING STARTED5To BeginUse the quote sheet attached at the end of the manual to identify the roller style and guide you through themeasurement process.n Do not limit the specifications to the quote sheets only; these sheets are only a guide for some of our most basicrollers and components.n For specials that do not fit one of the quote sheets, draw out the roller in detail with dimensions.Identifying Roller Stylen Gravity Rollers are rollers without a drive option.n Grooved Rollers have one or more grooves formed into the tubeand are driven with urethane bands.n Sprocketed Rollers have one or more sprockets weldedto the tube and are driven with chain.Identifying Roller Assemblyn Crimped- A crimped roller has a tube which is crimped down over the bearing to hold it in place. Bearings installed in thismanner are non-replaceable.- Edges of tube are bent towards the center.n Press Fit- A press fit roller has a tube which is counter bored to the correct inside diameter for the bearing to be press fit intoplace or slip fit for large diameter rollers.

6GETTING STARTEDIdentifying Axle RetentionSpring Retainedn Determine the axle retention by pressing one end of the axle in; if the axle pushes in, it is spring retained on theopposite end.n Repeat this process on the other end of the axle, if the axle reacts the same it is dual spring retained.n If the roller has sprockets or grooves it is important to identify which end the spring is on.Pin Retainedn Pin retained axles will have holes in the ends of the axles to insert the pins. When the pins are removed the axlecan be removed.- Measure the location and the diameter of the pin hole with the calipers.- Identify the type of pin. Our standard options include:Cotter PinHog RingNot RetainedA plain axle will not have any type of retention. No pins or springs will be holding the axle in place.Specialsn Fixed or staked axles can be identified when neither end pushes in, but axle cannot be removed.n Other special axles can be referred to in the axle machining section on page 10.

measurements7Between Frame (BF)n Between Frame (BF) is the distance between the side frames of a conveyor and it is the preferred dimension.- Sometimes referred to as between rail, inner rail or inner frame.n It is sometimes best to measure the conveyor equipment itself to get the BF.- Keep in mind there are some instances, such as a deep frame, or the way the rollers are set, where the OACis a better measurement. (explained below)n Use the tape measure to measure the distance between the two side frames to get the BF. Measure to thenearest 1/32".Between Frame Width (BF)OverAll Cone (OAC)n Overall Cone (OAC) is the distance between the two outermost bearing be made from mild steel, stainless steel, or polypropylene.n All bearings in this category are pressed into tubes and can be replaced.ABEC Precision Bearingsn Precision ground and polished raceways made from hardened chrome steel.n ABEC bearings have many styles, these are the most common that Omni uses:n Polypropylene Housed Bearings- Consist of a radial ABEC bearing inside a polypropylene housing assembly, typically black.- The housing must be crimped into the tube which means they are not replaceable.Flangen "All Metal" ABEC Bearings- Feature hex bores, extended inner races, and flanges.- Metal shields and rubber contact seals on both sidesof the bearing.ExtendedInner Racen Agricultural BearingsShield- Heavily sealed ABEC bearings designed for use in agricultural equipment.- Available with hex bores and square bores.- Available with both spherical and cylindrical body shapes.HexBore

BEARING TYPES19n Insert (Set screw) Bearings- Oversized round bores.- The inner race is extended and features set-screws, or some other mechanism, thatlocks the inner race to the axle.- Available with both spherical and cylindrical body shapes.Inner raceSet screwAssembliesCylindricalBodyShapen Adapter Bearings- Pressed into a stamped metal adapter.- Standard adapter assemblies must all be crimped into tubes.BearingAdaptern Sleeve Bearings- Large ABEC bearings, either Insert bearings or Agricultural bearings, with sphericalbody shapes that cannot be installed directly into a tube alone.- The sleeve is a machined piece of steel with a spherical inner diameter that thebearing can be installed into.Spherical Body ShapeSleeveAssembledPlastic Bearingsn The bodies are molded plastic, usually Acetal (Delrin).n The balls are 420 stainless steel.n Available in various colors.Bushings (Roll End Bearings)n Solid pieces of material with no rolling elements or moving parts.n Common tal (Delrin)UHMWLube-Filled HardwoodLube-FilledUHMW

20BEARING TYPESn FramesaverTapered Stub Axle- Framesaver Cartridges consist of two radial ABEC bearingsand a spring loaded stub axle in a polypropylene housing.- When installed in a roller they do not require a thru axle.- Use the picture to help identify framesavers, it can be difficult otherwiseto know for sure it is a framesaver unless the roller is cut to show no thru axle.- A
