Description
The Stem Caster Model G15 is a robust, heavy-duty industrial stem caster engineered for superior load-bearing capacity, boasting the highest capacity ratings among all stem caster models (up to 1,500 lbs per caster under ideal manual conditions, with weight directly on the swivel bearing). It is available with two stem types: threaded stems in ¾” and 1” diameters, and plain round stems in ¾”, ⅞”, 1”, and 1-⅜” diameters. For threaded stem casters, the weight is designed to be supported by the top of the swivel bearing, not the threaded stem itself, meaning they are not suitable for use as leveling devices. To ensure stability and safety, it is strongly recommended to fully thread the caster into the application. Plain round stems, on the other hand, are secured inside tubing by drilling a hole through both the tubing and stem, then inserting a bolt through the cross hole for a secure fit. The Model G15 is intended exclusively for hand-powered, manually moved applications (up to 3 mph on smooth floors), making it ideal for carts or equipment that are not mechanically driven, with capacities rated for infrequent movement without abuse.
This heavy duty industrial stem caster offers extensive customization through wheel and bearing options to suit diverse industrial needs, such as warehouse handling, material carts, or factory equipment. All wheels are consistently 2 inches wide for optimal stability and load distribution. Available wheel diameters include 4″, 5″, 6″, and 8″, allowing selection based on floor conditions, maneuverability, and capacity requirements—larger diameters generally provide better rollability over obstacles and less effort required to initiate movement.
Wheel materials (treads) vary to match specific applications, including:
- Rubber (e.g., gray soft rubber with crown tread): Quiet, floor-protecting, and non-marking for smooth indoor surfaces.
- Polyurethane (e.g., all polyurethane, crown orange polyurethane on iron core, red crown polyurethane on cast iron core): Durable, non-marking, and resistant to chemicals/oils, ideal for institutional or factory floors.
- Polyolefin: Lightweight, affordable, and impact-resistant for general use.
- Nylon: High-strength and abrasion-resistant for rougher surfaces.
- Phenolic: Hard and heat-resistant for heavy loads in dry environments.
- Steel: Caster City offers Ductile Steel and Forged Steel wheels as options for this heavy duty industrial caster.
Bearing choices for the wheels further enhance performance and longevity, with options including:
- B (Ball Bearings): Smooth rolling for moderate loads. Lowest initial force needed to get moving.
- BRNZ (Bronze): High Temperature Bearing for High Heat Applications. Low-maintenance and corrosion-resistant.
- D (Delrin): Self-lubricating plastic for quiet, lightweight operation where frequent wash-downs occur.
- PS (Precision Sealed Ball Bearings): Maintenance-free, high-precision for smoother, longer-lasting performance (standard on many polyurethane wheels).
- P (Plain Bore): Simple and economical for basic applications.
- R (Roller Bearings): Cost Effective and a great choice for many industrial applications.
The swivel construction features precision-machined combination load and thrust bearings with heat-treated raceways for reduced vibration, easier swiveling, and extended durability— Kingpinless Caster Design has no center pin and avoids weakpoints and failures occurring.
Optional add-ons enhance functionality:
- TB (Top Lock Brake): A pedal on the side of the wheel locks only the wheel’s rotation.
- TL (Total Lock Brake): Simultaneously locks both the wheel and the swivel mechanism for maximum stability.
- UFCB (Bolt-On Universal Face Contact Brake): A versatile, bolt-on brake that engages the wheel’s face to prevent movement.
- FCB (Heavy Duty Weld-On Face Contact Brake): A robust, permanently welded brake for heavy-duty applications requiring secure wheel locking.
These features, combined with the flexible wheel and bearing selections, make the G15 a versatile choice for industrial settings where durability, high load capacity, and customization are critical, provided the application aligns with its hand-powered design.
