Guide
Three caliper readings match a roller turn roller to a Frost part number: Overall Length (A), OD (B) and Bore Diameter (C). Overall Length tells you which conveyor the roller fits and which table to use. OD and Bore Diameter find the part number.
Before you start
You need calipers. Lock out and tag out the conveyor before you measure.
Step 01
Three numbers find your roller.
Measure with calipers, not a tape. Read each one to 0.01 in.
Fig. 1 · Standard roller shown. Every roller type is measured the same way.
| A | Overall LengthEnd to end, across the inner race at both ends. Take this one first. |
| B | OD (outer diameter)Across the outer race. A worn race can read small. |
| C | Bore DiameterInside jaws in the bore the bolt passes through. |
Step 02
Know your roller type.
Each type is a column in the part number tables. Not sure which one you have? Email us a photo.

StandardStyle 1, Style 2, Triple Lab.Full ball bearing with a nitrile contact seal. To 250°F (121°C) intermittent with Frost standard grease. 2,400 lb. |
 |
Special HD5/8 in bearingThe standard bearing with larger 5/8 in rolling elements for more load. 3,200 lb. Some come with Teflon-felt wipers. |
 |
Super HDTapered rollerTapered roller bearings for heavy loads, shock and thrust. To 250°F (121°C). 5,000 lb. |
 |
High Temp.Style 3A journal bearing with no rolling elements, for ovens. Up to 800°F (427°C) continuous. 2,200 lb. |
Step 03
Find your table.
Your Overall Length (A) tells you which conveyor the roller fits and where its part numbers are.

How to read the tables
OD (B) picks the band. Bore Diameter (C), .50, .58, .63 or .75, picks the row. Your roller type picks the column. Example: 2.75 Overall Length, 2.75 OD and .75 Bore Diameter is a Standard Style 1, part number 0407000.

Questions we hear a lot.
How do you measure a roller turn roller?
Use calipers and read three numbers to 0.01 in: Overall Length end to end across the inner race, OD across the outer race, and Bore Diameter inside the bore the bolt passes through.
Which measurement do I take first?
Overall Length. 1.52 in fits X-228 conveyors, 1.87 or 2.13 in fits 3″ conveyors, and 2.75 or 2.81 in fits 4″ and 6″ conveyors.
What is the difference between Special HD and Super HD roller turn rollers?
Special HD uses the standard bearing with larger 5/8 in rolling elements and is rated 3,200 lb. Super HD uses tapered roller bearings for heavy loads, shock and thrust and is rated 5,000 lb.
