Steel Trolley Wheels
3" Stud Type Wheel
Frost 3″ stud type trolley wheels have an integral threaded stud that bolts into the trolley bracket.
Of the 10 part numbers, 8 are retainer and 2 are full ball complement. Seals: Splashproof® (6), triple labyrinth (2) and contact lip seal (2). Studs are 7/16-20NF on most wheels, with 1/2-20NF (5702000) and 5/8-18NF (3286000) versions.
Flat tread wheels are marked * in the table: 3280000, 3281000 and 3286000.
A 3″ retainer wheel runs 7 balls in a steel separator for the lowest friction, rated to 325°F. A 3″ full ball complement wheel runs 11 balls with no separator for heavy load and contamination, rated to 500°F. Our wheel configuration guide shows how to tell them apart.
