All-Flex Series: Specifications

ENCLOSED TRACK:

The track is a rolled tubular section of SAE 1035 high carbon manganese steel, stocked in 10′-0″ & 20′-0″ lengths. Available in #316 Stainless Steel on special order.

CHAIN PULL:

The maximum recommended chain pull should be limited to 600 pounds using a single drive unit, providing a safety factor of 8.25:1 to obtain maximum chain life. Ultimate tensile strength is 4,950 pounds.

GUIDE WHEEL LINK:

1-1/2″ diameter machined steel wheel heat treated to Rockwell 58 – 62 on the “C” scale C/W 14 Grade 500 balls .187″ dia. riveted to double chain side bars of C-1045 high carbon steel hardened to Rockwell 37 – 41 “C” scale.

 

LOAD LINK:

Load Link to consist of two 1-3/8″ dia. wheels heat treated to Rockwell 58 – 62 on the “C” scale. Each wheel C/W 14 Grade 500 balls .187″ dia. riveted to a single chain link .188″ thick C-1045 high carbon steel hardened to Rockwell 37 – 41 “C” scale.

CHAIN ASSEMBLY:

6″ Nominal Pitch 50 lb. Loading Per Trolley Weight 1.6 lb/ft.

8 TOOTH 180°
SPROCKET DRIVE:

The sprocket drive is the simplest, most economical drive available, consisting of the minimum number of components, resulting in a lower maintenance cost.

AF-60033
8 TOOTH 90°
SPROCKET DRIVE:

All-Flex offers a 90 & 180 degree sprocket drive & an in-line sprocket drive to suit most system layout requirements. A conventional caterpillar drive is available to suit any unusual requirements. All drive units have overload protection as required by the safety regulator.

8 TOOTH INLINE
SPROCKET DRIVE:

Safety guards on the drive units comply with applicable OSHA & ANSI B20.1 Standards.

CATERPILLAR DRIVE:

• Max. chain pull capacity: 600 lbs.
• Combination right angle (helical worm) gear motor.
• Forged heat-treated caterpillar driving dogs.
• Chain guard supplied with each drive.
• Multiple drives are required when chain pull exceeds 600 lbs.
• Variable frequency drive controller available on request.
• Maximum conveyor speed should not exceed 60 F.P.M. with standard drive sprockets.

CATERPILLAR DRIVE
OVERLOAD PROTECTION:

Overload protection supplied by SRS torque limiter used with limit switch to cut off power.

SPROCKET DRIVE
OVERLOAD PROTECTION:

Each sprocket drive has a friction type torque limiter built into the sprocket hub.

TAKE-UP:

ake-ups are required on every system to compensate for chain wear and expansion of system if operating in dry-off and bake ovens. The two most common operating styles are air cylinder and automatic spring.
Standard 12″ radius x 6 1/2″ travel units are stocked.
Available in other radii & travel on special order.

SPROCKET TAKE-UPS:

8 tooth & 6 tooth idler sprocket take-ups are available in air & spring styles.

HORIZONTAL SPROCKET TURNS:

When the conveyor layout requires track horizontal turns less than 12″ radius (24″ diameter) sprocket turns should be considered to reduce the resultant chain pull and wear on the track radius and the side guide rollers on the chain.

Sprocket hubs can be supplied using conventional needle bearing or carbon bushing for oven applications of up to 500° F.

HORIZONTAL TRACK TURNS:

This top view illustration shows how the chain passes around the curve. The lateral wheels ride on the side of the track, which guides the chain smoothly around a horizontal turn without the use of special guides, traction wheels or roller turns. All horizontal curves are heat treated to rockwell 35 to 40 “C” scale for long life.

VERTICAL TRACK TURNS:

This vertical curve side view illustrates how the chain passes around the curve. The vertical chain wheels contact the top of the lower curve and the bottom of the upper curve. All vertical curves are heat treated to rockwell 35 to 40 “C” scale for a long life.
