Edgerton Gear makes moulder feed rollers in all diameters, widths, and bores. Send us your drawings and specifications, or send us your worn and broken parts for reverse engineering. We'll harden the roller teeth, which can be resharpened several times, saving you about one-third the cost of a new roller with each reuse.
140 mm x 0.625 in x 30 mm-TH-LH-SB-BS
It's economical to resharpen old parts.
140 mm x 2.00 in x 35 mm-TH-LH-ST-K-W
When quoting a feed roller, we use the following format:
"o.d. x width x bore" followed by abbreviations for other features.
Here's an example:
140 mm x 1.75 in x 35 mm -TH-RH-ST-K-H-W
Key to Abbreviations
TH or KN = teeth or knurled outside diameter
LH or RH = left-hand or right-hand helix angle
ST = set screw through teeth
GT = grooved teeth
TS = teeth straight
K = keyway
H = hub
SH = set screw in hub
W = webbed out (to remove weight)
SF = set screw at an angle in face
IL = interlocking w/each other
SB = special bolt pattern
BS = bolt-on style
CB = counter bore
WN = window
SW = set screw through window
TOD = tapered outside diameter
HB = herringbone style (set)
SP = other special machining
Note: All feed rollers have their teeth (or knurl) hardened
to 53 - 58 Rockwell Scale C.
