Specifications Standard Steel Wheel Sani-Trolley
Wheel design Available for standard 3”, 4” and 6” I-Beam. Both retainer type and full ball complement style wheels (see next page more for more information). Available for standard 3” I-Beam.
Design - Double row, free rolling full-ball complement bearing design with stainless steel inner raceways and balls and stainless steel outer raceway inserts for increased load capacity and bearing life. Plastic wheels eliminate rail flaking, wear problems and noise.
Contamination Frost meat processing trolley wheels are available in plated steel. Stainless Steel trolleys are available for high corrosion environments. High levels of dry or liquid contamination can be tolerated by using Frost Splashproof® seals. Plastic wheel and ball bearing wheel construction is designed to resist corrosion in normal environments of food processing, resist attack from cleaning solutions, and have easy access for lubrication and cleaning.
Lubrication Wheels are factory sealed with U.S.D.A. approved lubricant to your specification. Wheels are designed to operate with minimum of required lubrication. Daily spray cleaning with high pressure water and application of U.S.D.A. approved light oil will greatly increase bearing life.

Features Full Ball Complement(FBC) Retainer Type                                                                    
Energy Consideration

Moderate Horsepower Required

Frost standard FBC type trolley wheels
are designed without a ball separator.
Because of the ball-to-ball sliding contact
and the demand for more chain pull,
horsepower requirements are increased.

Low Horsepower Required

Frost retainer type trolley wheel construction is of the Conrad type (single row bearing with balls spaced apart by a coined, two-piece steel ball separator). This wheel design (with balls separated) causes low friction and requires the least amount of conveyor drive horsepower.                                                                                                        
Raceway Design

Split Inner Raceway

Hardened and Fully Contoured Frost standard FBC wheels have an extremely deep-groove, fully contoured inner raceway and can operate continuously under heavy (two-directional) radial and thrust loads. The construction advantages are: 1) High raceway shoulders for maximum thrust load capacity; 2) Split inner raceway allows for deeper ball path and more balls for maximum load-carrying capability; 3) The raceway rings have a double lock feature. This provides a positive, dual direction lock assuring that the split inner rings will not spread apart.

Non-Split Raceway

Hardened and Fully Contoured Frost retainer type wheels have a one-piece inner raceway, fully contoured on both sides of the ball for light, continuous thrust and radial load carrying capability.
Internal Fit-Up

Greater Clearance

Frost standard FBC wheels have greater internal raceway clearance for misalignment tolerance and to prevent bearing freezeup due to dirt contamination and/or heat expansion. For higher temperatures and contamination, Frost can provide one less ball, special materials or extra clearance upon request.

Normal Clearance

Frost retainer type wheels have normal internal radial fit-up and a ball separator to ensure smooth rolling operation, yet ample clearance for misalignment tolerance.
Heat Capability

500°F (260°C)

Frost standard FBC wheels were designed for temperatures up to 500°F (260°C). For temperature applications above 500°F, Frost should be informed so that extra internal clearances can be provided.

325°F (162°C)

Frost retainer type wheels can be safely used up to 325°F (162°C). This limitation is due to less internal clearance for heat expansion of bearing components.
Contamination Tolerance

Heavy Contamination

Frost standard FBC wheels can withstand heavy contamination levels (dry or liquid) and operate best with triple labyrinth seals. Added contamination tolerance can be obtained by using contact lip seals.

Moderate Contamination

Frost retainer type wheels can withstand moderate contamination levels. Added contamination tolerance can be obtained by using contact lip seals.
Load Capacity

High Load Capacity

Frost standard FBC wheels have greater load capacity than retainer type wheels due to the increased number of balls. Specifically designed for maximum load situations, standard FBC wheels can handle peak and continuous radial and thrust loads acting from any direction. They are the best choice for shock and impact loading. Note: In system design, I-Beam is the limiting load factor.

Moderate Load Capacity

Frost retainer type wheels have the highest load capacity of any available retainer type wheels. Although this capacity is exceeded by full ball complement wheels, Frost retainer type wheels have ample load capacity for most conveyor systems. Note: In system design, I-Beam is the limiting load factor.

Trolley and Wheel Load Ratings

Maximum trolley load rating is not determined by the load rating of the wheel (bearing), but is equivalent to the load before peening (indenting) the I-Beam or C-Channel. Based on standard medium carbon I-Beam or C-Channel, the figures most often used are 200 lbs. maximum capacity per pair of 3 inch trolleys, 400 lbs. per pair of 4 inch trolleys and 1200 lbs. per pair of 6 inch trolleys. Please consult with Frost engineers for special applications or multiple wheel load ratings. The chart below provides load ratings for your reference.
*Dynamic load rating based on pure radial running conditions at 50 RPM. B-10 Life 5,000 hours according to AFBMA standards. This load rating is based on conditions of moderate shock, proper lubrication and maintenance, and normal temperature, (250°F (121°C) and under).
