Heavy section conveyor rollers fall into two basic categories – drive and gravity rollers. Unlike thedriven light duty rollers in the 1.5", 1.9" and 2.5" diameters which are driven by "O" sectionbelts, heavy duty conveyor rollers are typically chain driven and are known in the tradeas Chain Driven Live Roller or CDLR’s.

TubingThe most common diameters used in Heavy DutyRollers are 2.5", 3", 3.5", 4" and 5". Carbonsteel is used most frequently. We alsooffer roller tubes in stainless,heavier sections of PVCand aluminum. Themost commonwall thicknessis 11 gauge -.120 wall.

BearingsThe variety bearing systems for conveyor rolls is near infinite. For Heavy Duty Rollers we use prima-rily one of the three following systems:

Precision Bearing Assembly consists ofa Precision grade 6205 bearing withhardened and ground chrome-steelraces and seals. For optimum strengthand concentricity when mounted in theroller assembly, the bearing OD ispressed into a CNC machined precisionadapter, which is then press fit into thebore of the roller tube. A CNC adapterwith a machined 11/16 or 5/8 hex boreis then press fit into the bore of thebearing. This combination of precisionmachined OD and Bore adapters with aground bearing offer the highest speedcapacity, lowest noise, and greateststatic and dynamic load capacities.

For lower loads and speeds we offer a Swage Fit ConveyorRoll Bearing. Available in a 5/8 or 11/16 hex bore thesebearings press fit directly into 2.5" tubes. These bearingsfeature a polymer seal to protect the bearing from particu-late contamination. They are the most cost effective way toproduce 2.5" diameter Heavy Duty Rolls.

Press Fit Un-ground Bearings are used over the full rangeof heavy-duty roller diameters. These bearings are availablewith a 5/8" or 11/16" hex. When used in rollers exceedingØ2.50" OD, the bearings are press fit into either a .125"thick washer that is welded into the tube, or a CNC preci-sion bearing to tube adapter as used with PrecisionBearings. This adapter is machined to a width that equalsthe face width of the bearing, and therefore, offers moresurface engagement than a washer. This design offersgreater resistance to impact and moment loads, andgreater static capacity than a washer type adapter. Like the swage fit bearing, the press fit bear-ings offer a cost effective way to produce heavy-duty rollers for average speed and load applica-tions. They are fitted with a polymer seal to offer protection against particulate contaminants.

AxlesAxles are available in round or hex stock. Materials used are carbon steel, stainless steel and alu-minum. The most common hex sizes used for HD Rollers are 5/8" and 11/16" with 11/16" the fardominant size. For many palate-handling conveyors, the end of the hex is cross-drilled to allow acotter pin to secure the hex laterally in the conveyor frame.

Round axles are also available. Most round axle rollers have some feature to lock them in place inthe frame to insure that the roller turns about the axle while preventing axles rotation in the frame.This can be most frequently accomplished by end drilling and tapping the axle and securing it to theframe with bolts on each end.
